Overcoming KB5050009 Update Errors

January 17, 2025 Ed Tittel Leave a comment

I’ve seen it before. And I’m grimly resigned to seeing it again. Every now and then, a Windows PC has issues with some Windows Update (WU) item. Mostly, though, I’ve seen this with Cumulative Updates (CUs) rather than security, MSRT, or servicing stack items. Indeed, this very situation popped up on a brand-new review unit from Lenovo following Patch Tuesday this week which brought KB5050009 to Windows 11 24H2. On all four of my other production level 24H2 PCs, no problem. On the ThinkCentre M90a (see yesterday’s intake review) however, I spent some time overcoming KB5050009 update errors. Let me explain…

Escalating Steps When Overcoming KB5050009 Update Errors

I’ve been through this kind of thing often enough that I’ve got a series of steps I follow when a WU update fails and throws an error. Here it is:

1. Write down the error string ( 0X800F081F in this case)
2. Run the WU update again (helpfully, it offers a “Retry” button)
3. If it fails, note the error message. Record only if different from 1.
4. Download and run the batch file from Eleven Forums Reset Windows Update tutorial (Batch file named Reset_Reregister_ Windows_Update_Components_for_Windows11 .zip).
5. Try again. It it fails. note the error message if different from 1.
6. Download the self-installing update file (.msu) from the Microsoft Update Catalog, then install.
7. If it fails, note the error message. Record only if different from 1.
8. Visit UUPdump.net. Create an ISO file for the target Build (26100.2894, as per KB5050009 support note).
9. Perform an in-place upgrade repair install on the affected PC. This applies the already-integrated CU as part of that process.
10. If that fails, perform a clean Windows install using the UUPdump ISO.

I’ve only had to beyond step 5 in a small number of instances in the 30-plus years I’ve been using Windows. This was one of those cases. To my surprise the catalog download failed the the same error message as before. Next, it took an hour and half to download and build the 26100.2894 ISO, and another 50 minutes or so to install that image on the ThinkCentre. Ouch!

One Step Short of Clean Install Works

But when the PC rebooted, it came up with no errors. Interestingly, the Update History does not show KB5050009, even though it must be present for the build number to reach 26100.2894. You can see this in the lead-in graphic, which shows that very build number, but not the CU entry for KB5050009. That’s because it was part of the install image when the upgrade repair install occurred, not added separately via WU.

But it does go to show that here in Windows-World, when WU won’t work, there may sometimes be a way to work around its failings. This is such a tale…

PostScript: About the 0X800F081F Message

Here’s what Copilot says about this error message, thanks to info from answers.microsoft.com:

The error code 0x800F081F typically occurs when the Deployment Image Servicing and Management (DISM) tool is unable to find the necessary source files to repair the Windows image. This can happen during Windows updates or when running the DISM /Online /Cleanup-Image /RestoreHealth command.

To me that indicates there was some WU issue with the files included in the update package that got downloaded from the WU servers. Curiously it also seems to have affected the Catalog item. I’ve never had that happen to me before. Go figure!

Strange But Lovable Lenovo AIO

January 16, 2025 Ed Tittel Leave a comment

An AIO is an “all-in-one” — namely, a monitor with a mini-PC slung on its back, usually built from laptop parts. It’s got everything you need to compute except mouse and keyboard (and Lenovo sent those, too, along with the unit and power cord). I’ve owned and enjoyed numerous AIOs over the years. Thus, I was intrigued to learn more about what Lenovo might offer me in that line. They sent me the ThinkCentre M90a Gen 5 in December, but I’m only now writing about this strange but lovable Lenovo AIO .

Digging Into a Strange But Lovable Lenovo AlO

Let me tell you more about this beast: it combines numerous odd or even anachronistic features with a capable CPU, lots of ports, and a surprisingly vibrant and good-looking screen. Here’s a list of what was present on the review unit Lenovo sent me:

CPU: Core i7-14700 (8 P cores, 12 E cores, 28 threads total)
RAM: 2x DDR5-5600 16 GB (32 GB total)
Graphics: Integrated Intel UHD Graphics 770
Disk: 1x 1 TB SK Hynix HFS001TEJ9X164N NVMe SSD Gen4
Display: 23.8″ color calibrated touch display (1920×1080 HD)
Networking: Intel AX211 Wi-Fi 6E and RJ-45 for GbE
Ports: 3x 10 Gbps USB-A, 3x 5 Gbps USB-A, 1x 10 Gbps USB-C
Camera: 5 MP RGBIR (Windows Hello ready) [accessory]
OS: Windows 11 Pro 24H2
Mouse & Keyboard included (very basic house brand)

As configured, this unit goes for US$2,133.00 at the Lenovo Store. Prices go up and down there, and at resellers, so use this as a guidepost rather than a “must-pay” number. If you shop around you may find a better price.

Strange (Anachronistic) vs. Lovable

What makes the M90s strange — IMO anyway — is its inclusion of an optical (DVD only, not Blu-ray) drive, no add-in GPU support, and only USB 3.2 5 and 10 Gbps ports (no USB4 or TB4 ports at all). The unit refused to recognize a USB4 NVMe enclosure when I plugged it in (across all ports). That’s strange, and a bit frustrating, on a business-oriented (says Lenovo) AIO. The unit does support a second SSD slot (M.2 2080 module replaces the DVD drive). One could also insert a SATA SSD into the currently unoccupied hard disk slot inside the case.

What makes this unit lovable is its bitchin’ fast performance (the i7-14700 is wicked fast) and its eminently viewable display. I plugged an Acer 38″ monitor into DisplayPort on the back and easily drove the built-in 23.8″ (1920×1080) and the external 38″ (3840×2160) for an enormous desktop. Great fun!

There are plenty of ports available (albeit slower ones) and I was able to accommodate SSDs (mSATA and NVMe) and various hard disks in their respective enclosures. The internal SSD topped out at ~5 GiB read and 4+GiB write speeds (via CrystalDiskMark 8.0.6 x64 version). Because of port speed limits, 500 Mbps is about as fast as external media will run (on par with a SATA SSD, in fact).

Intended and Possible Uses for M90a Gen 5

Personally, I see this kind of PC as an ideal choice for a dorm room PC, or for office workers in typical productivity jobs (not developers or creatives, but most everybody else). It offers good value for the money if you let Lenovo emplace the parts. That value jumps if you buy minimally configured units and upgrade them yourself (e.g. RAM and storage, including a 2nd internal SSD and a SATA SSD in the HD slot). It’s a pretty solid workhorse if somewhat long in the tooth…

Dead CMOS Mungs Boot Behavior

January 15, 2025 Ed Tittel Leave a comment

It’s one thing to know something in the abstract. It’s entirely another to have it hit you in the face. Today, I went to log in to my son’s PC to update the BIOS to wake on LAN (WoL). No dice. I couldn’t get anything to get me into UEFI, not System > Recovery > Advanced Startup; not the Asrock Restart to UEFI utility, not even shutdown /r /fw /t 00. Then it hit me: could the CMOS battery be dead? Sure enough, a new CR2032 lithium coin battery fixed the problem. And I was forcibly reminded that a dead CMOS mungs boot behavior.

New Battery Fixes Dead CMOS Mungs Boot Behavior

I happened to have 7 of the 10 (now 6) CR2032s I bought via Amazon in 2023 still on hand. With an expiration date in the 2nd half of 2027, I felt comfortable swapping in this newer battery in place of the dead one. As soon as I’d done that, then recabled everything — alas I had to unseat the GPU to reach the battery receptacle — the system resumed proper, normal boot behavior.

Take this lesson from me: if you ever find yourself unable to get to UEFI, WinRE, or other boot menus and displays, check the CMOS battery. If you’re as lucky as I was today, replacing same will fix your issue(s) as it did mine. Cheers!

And ain’t that just the way things go sometimes, here in Windows-World? You betcha… There is an upside though: with the BIOS/UEFI change I was finally able to make, I can now remote into the upstairs Ryzen PC thanks to Wake on LAN (WoL). All’s well that ends the same way.

OhMyPosh Auto Update Hangover Fixed

January 14, 2025 Ed Tittel Leave a comment

Here’s an interesting one. Indeed one can configure or enable the excellent OhMyPosh prompt tweaking tool (aka OMP) to update itself. But there’s a trick involved in getting WinGet to recognize an update has occurred. I call it an “update hangover.” Apparently the local copy of the WinGet source list itself needs a reset before it catches up with what’s happened. (That list provides the basis from which it decides what’s fresh and what needs updating.) Let me explain — and show — how I got this OhMyPosh auto update hangover fixed.

Getting OhMyPosh Auto Update Hangover Fixed

Take a look at the screencap in the lead-in graphic. Before this sequence occurred, OMP told me as the PowerShell session started up that it was updating itself to version 24.18.1. You’ll notice that selfsame “Available” version according to WinGet upgrade output right at the head of that PowerShell command sequence.

Keep reading. Note that the output for oh-my-posh –version also reads 24.18.1. Thus, OMP is already upgraded and already current. But after I complete the valid remaining upgrade manually (for Microsoft.WindowsADK), another simple upgrade check shows that WinGet thinks OMP still needs that upgrade.

What to do? I try basic winget source reset — which attempts a reset for the winget and msstore sources — but the command output tells me the directive requires the –force option to work. So that’s what I try next:

winget source reset –name winget –force

As you can see when I do the next upgrade check after that, WinGet now reports “No installed package found matching input criteria.” That means it no longer sees OMP as a legit update target. Fixed!

Now, I wonder if Jan DeDobbeleer can figure out a way to reset the local list of packages for comparison to the WinGet source as part of his auto-update function. Probably not: knowing his thorough and deliberate approach to this package, he’d have done it already were that possible.

Copilot+ PCs Lack Fast I/O

January 13, 2025 Ed Tittel Leave a comment

So I’ve been doing some homework. I’ve checked on the MS Copilot+ PC hardware requirements. I’ve also looked at related announcements from Qualcomm, Intel and AMD regarding reference designs for such PCs. So far, nobody’s talking about Thunderbolt 5/USB 5 (aka USB4 v2) support on such PCs. That’s kind of a shame, because supporting gear is becoming available for purchase right now (see last week’s post First TB5 NVMe Enclosures Drop for more info). Be that as it may, so far Copilot+ PCs lack fast I/O support via USB-C attached devices. That’s a shame!

If Copilot+ PCs Lack Fast I/O, Then What?

To be fair, USB4 with some degree of TB4 support is baked into the existing specfiications and reference architectures. And, FWIW, the Qualcomm SoC implementation is pretty darn good — not quite as fast as Intel’s but entirely acceptable. That tells me support for TB5/USB5 is probably coming “real soon now” (to resurrect Jerry Pournelle’s famous phrase from his Chaos Manor column).

My best guess is we’ll see a revision to Copilot+ PC specifications some time later this year (the original set emerged in May 2024). I’m thinking sometime around or shortly after the first anniversary seems pretty likely.

In the meantime, Copilot+ PC users will have to live with 3-3,500 Mbps read/write speeds typical of USB4/TB4 device chains for NVMe storage devices. The new spec should double those numbers, and make those who use external NVMe storage for videos, backups and other high-volume, high-traffic I/O applications happy.

You’ll Pay for That Pleasure, Though

If what I’m seeing for NVMe enclosure costs is any indication — namely US$200 and up — users who buy into faster I/O sooner rather than later will pay a premium for those speeds. The Acasis 40 Gbps enclosures run US$90 (fanless) or US$110 (with fan). The same vendor’s TB5 model has an MSRP of US$299 (and is available on sale at Newegg right now for US$239). Yikes!

Note, Intel unveiled its specs and controllers for Barlow Ridge TB5 on January 9 (last Thursday) so it’s no wonder that PCs with such circuitry built in are hard to find right now. Go figure! Hopefully, licensees will ante up soon. I’m curious to see if once again Qualcomm will reverse engineer this stuff… The comparison slide vis-a-vis TB4, USB4 and USB3/DP from Intel’s Jan 9 announcement serves as the lead-in graphic for this very blog post, in fact.

Final thoughts: ThinkBook Plus 5G Android Connection

January 8, 2025 Ed Tittel Leave a comment

Now that I’ve had — and used — the hybrid ThinkBook Plus 5G (TB5G) for 8 weeks or so, I’m ready to close out my eval and send it back to Lenovo. That said, my final thoughts are: the ThinkBook Plus 5G Android connection is what makes (or breaks) a buying decision. Those with Android phones they’d like to integrate will find that link-up much more convivial and useful than those with iPhone devices. Alas, I’m a member of the latter club, so I’m coming down on the “won’t buy” side of the equation. I like the PC, but not enough to buy this particular dream.

The ThinkBook Plus 5G Android Connection Is Vital

As is often true for hybrid devices, I also found the TB5G configuration somewhat brittle. I ran into initial difficulties upgrading the device from 23H2 (as shipped) to 24H2 (once WU started offering that version). It did succeed on a later try, so MS obviously took steps to accommodate its hybrid storage. It creates a shared “exchange zone” between the Android tablet/display and the Wintel Core Ultra 7 155H-based keyboard deck. Obviously, it also requires special handling during Windows install and upgrade.

This also went by the wayside when, as an experiment, I let Snappy SDIO loose on the device’s drivers with a doomed across-the-board upgrade. That experiment goes in the “major fail” column, as it left the PC without working cursor, keyboard or touch display upon completion. That fail was severe enough, in fact, that I had to use the “reboot three times” method to get into WinRE and reset the PC from the cloud to restore it to working condition. After that, in fact, it took an upgrade to “Hybrid Center” to bring the Hybrid Folder (A:) back to the desktop…

A Large But Likable Beast

Overall, the unit behaved well, and did what I asked it to do during the eval process. It’s heavier than most ThinkPads, though, and I found it harder to lug than most other Lenovos I’ve tried out in the past 4-5 years (3.9lbs/1.77kg: 2.14lbs/0.97kg base; 1.73lbs/.80kb tablet-display). If I have the price right (my 32 GB, 1 TB SSD, 155H configuration appears to cost around US$2K) it’s a bit pricey, but offers good performance and interesting capabilities.

In the end, it comes down to whether or not you’ve bought into Android or iPhone telephony. It integrated well with my aging Motorola Razr Android phone. With my iPhone 12, not much differentiated it from other Windows laptops. That’s why I’m making the Android call on “who’s most interested” where this device is concerned.

For my money, the lack of Copilot+ PC capability outweighs the “ooh” factor in a laptop with a detachable, independently usable display. I’m ordinarily a sucker for such devices — and have owned models from Dell, Fujitsu, Microsoft, and Lenovo in this category. But lacking the right NPU configuration, this device doesn’t make that grade. Back it goes…

New OhMyPosh Version Highlights Auto-Update

January 7, 2025 Ed Tittel Leave a comment

As the world returned to a more normal work rhythm yesterday, I found myself fielding various new software updates. Among them, a bump to OhMyPosh version 24.18.0. It wouldn’t work via WinGet because — as you can see in the lead-in graphic — it introduces a “newer version” for its “install technology.” Thus, this new OhMyPosh version highlights auto-update gotcha. I’d already used the oh-my-posh enable upgrade command to automate that process. A new install wipes out that directive.

If New OhMyPosh Version Highlights Auto-Update, Then What?

This got me looking at ways to embed the same information in the omp.json file that drives OhMyPosh configurations. Turns out when a reinstall happens, default configurations are rewritten from scratch. Thus, adding commands to

“auto_upgrade”: true,
“disable_notice”: true,

likewise got wiped from my chosen JanDeDobbelleer.omp.json config file as well. (Add them to the end of that file and you’ll need to drop the second comma, in fact.) What to do?

Turns out a custom config file is left alone when you have to shift from an older install technology to a newer one. Renaming the default config file, adding customizations, and referencing that new name in the invocation for OMP will do the trick. Way to learn, I guess!

Best Gets Better, After Sussing Out the Wrinkles

My fervent thanks to Jan DeDobbelleer, the OMP developer and chief steward. There’s seldom anything that goes off with OMP that isn’t addressed in his copious documentation and online interactions with other users. It sometimes takes a little while — about half an hour for this set-to, for example — but I have always been able to figure out and fix whatever gets hinky with OMP. That’s quite a testament to the tool and its builder. Thanks again for everything, Jan!

2025 Is PC Refresh Year

January 6, 2025 Ed Tittel 2 Comments

I’m not sure what to make of Microsoft’s blog post for CES 2024, entitled “The Year of the Windows 11 PC Refresh.” According to StatCounter, as of December 2024, Windows 11 holds a 34.11% market share, as compared to Windows 10 at 62.7%. That puts 11 at around 55% of 10 by those numbers. If indeed 2024 is PC refresh year for Windows 11, as MS says, it’s got a lot of ground to make up.

Why Say: 2025 Is PC Refresh Year?

Indeed, MS concludes the afore-cited blog post with these concluding words:

…we believe that one of the most important pieces of technology people will look to refresh in 2025 isn’t the refrigerator, the television or their mobile phone. It will be their Windows 10 PC, and they will move forward with Windows 11.

The impetus, of course, from the MS POV is that Windows 11 running on a Copilot+ PC provides significant new capabilities in the areas of security and AI-driven content creation, bolstered by faster, more powerful hardware with longer battery life. Given such a compelling combination of features and functions, the case for refresh is too strong for any other outcome to be likely.

Impending End of Service for Windows 10

October 14, 2025 remains the end of the officially supported road for Windows 10, with subsequent yearly payments for extended service after the cut-off date. MS will bump costs annually for up to three years after that time, to allow laggards to pay for the privilege of postponing refreshes instead.

Does this all translate into 2025 as a notable refresh year? It could, provided that consumers and businesses buy into the notion that what Windows 11 24H2 brings to the party is worth the time, cost and effort to push a refresh through sooner rather than later.

IMO, what’s more compelling to consumers and businesses is the age of their PC fleets, and how long it might be until a refresh occurs as per normal 3-5 year cycles. Looking at my modest collection of a dozen units or so, 3 of them date from 2018, and another three pre-date 2022. That would argue for a 60% refresh rate here at Chez Tittel. I suspect many small to mid-size businesses, and even enterprises, are in a similar boat.

Could 2025 be a big year for PC refreshes? Possibly. Will that actually happen? It depends on how appetites for new technology match up with the will and the wherewithal to acquire Copilot+ PCs. I suspect 2025 will see more refresh activity that 2024 did. But I’ll be surprised if Window 10 and 11 marketshare flip-flops — that is, 30-40% Windows 10 versus 50-60% for Windows 11 by the end of the year. That said, stranger things have happened.

My own best guess is that Windows 10 and 11 might reach parity — which currently calculates to ~48% each — by 12/31/2025. But I see that as a stretch target based on current numbers and prior version histories. Of course, only time will tell… Stay tuned!

Avoid Mystery Pop-up Windows

January 3, 2025 Ed Tittel Leave a comment

It’s now a truism that one should NEVER click links in email from unknown or untrusted sources. This morning, I was reminded the same is true inside a browser. There, one should avoid mystery pop-up windows with equal attention and suspicion. Indeed, this happened as I visited one of my daily Windows-related news and info sites, much to my alarm and dismay.

Why Avoid Mystery Pop-Up Windows?

Any time you’re presented with a link you don’t recognize, didn’t ask for — and probably also, don’t want — leave it alone. In my case, I clicked CTRL-Shift-ESC to launch Task Manager. Then, I killed all related browser processes. After that, I restarted Firefox anew. It’s never smart to take any such bait, nor to let it linger on your desktop.

Indeed, Task Manager might have refused to kill one or more Firefox processes. Then, my next step would be: restart my PC, then run an immediate virus scan. As it was, an immediate follow-up scan showed Defender still on the job. It revealed neither lurking threats nor suspicious files. Good-oh!

You’ve Been Pwned!

Right here at edtittel.com, I fought off a series of WordPress-induced injection attacks last year. I ended up having to buy into a security service that prevented hijackers from altering URLs published into social media sites (e.g. X, Facebook and LinkedIn). These redirected would-be blog post visitors to certain potentially unsavory stop-offs en route to my daily posts. It now costs me $300 a year to protect website visitors from such stuff and nonsense.

I say this to explain that such things can happen to almost any website, at any time, as unpatched vulnerabilities get exploited. Knowing that this is always a possibility, savvy users recognize that mystery pop-ups hide much more malice and potential for harm than sources for wonder and beauty. Avoid them at all costs, is received security wisdom — and my best advice as well. That goes double if they come bearing offers that seem too good to be true…

DSA Update Succeeds Where Lenovo Vantage Fails

January 2, 2025 Ed Tittel Leave a comment

Go figure! When Lenovo Vantage reported this morning that the ThinkStation P3 Ultra needed a new Intel Wi-Fi driver, I thought nothing of it. I elected the install, fired it off, and waited for the results. Oops: “Failed to install.” Tried again, and got the same result. So I checked Intel’s Driver and Support Assistant (DSA). Sure enough it reported the same outdated driver (23.60.0.10) and the same incoming new replacement (23.100.0.4). But that DSA update succeeds where Lenovo Vantage fails. As you can see in the lead-in graphic, a subsequent Vantage update check post-DSA reports no updates available (and shows a failed attempt below).

Guessing Why DSA Update Succeeds Where Lenovo Vantage Fails

I’m a great believer in the old principle that “if one tool fails, try a different one.” What’s trickier is figuring out why Vantage falls over while DSA does the job correctly. Copilot speculates it could have to do with compatibility, permissions, or software conflicts. Turns out one must enable a registry setting to get Vantage to log and report on failures — absent on the P3 Ultra, alas — so I can’t really tell what went south when Commercial Vantage did its thing.

If it were really important (and I hadn’t found an immediate and easy workaround) that’s what I’d be doing next. The key string involved is:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Lenovo\
SystemUpdateAddin\Logs

The REG-SZ (registry string) value named “EnableLogs” needs to be changed from its default value of “False” to “True” for subsequent logging to occur. I’ve made that change, and will check out if and when future Vantage install or other update errors occur. Good stuff!

Prepped for the next gotcha: logging enabled.

Hopefully next time I won’t have to guess what happened. The log should tell me something. Whether I can parse its meaning is a whole ‘nother challenge!
