Whoa! Things are getting pretty esoteric. Via Reliability Monitor, I just got caught in a File Explorer AppHangB1 AppHang81 gotcha. But first, let me explain that following last Fall’s cataract surgery, I can’t see the fine print without my reading glasses anymore. I cheerfully confess I can’t see the difference between the “B1” and the “81” parts of those Problem Event Names in ReliMon unless I put my glasses on. So I have to laugh.

Overcoming Explorer AppHangB1 AppHang81 Gotcha

I looked up the error code — which I initially read with the “81” suffix — using Copilot. I immediately wondered why it had two paragraphs about the same topic (see below). Then it hit me: I needed better visual acuity to see and understand what Relimon and Copilot were trying to tell me.

Upon closer examination “8” and “B” are close, but NOT the same!

Once IDed, It’s Neither Scary nor Well-Lit

Further research into these AppHangB1 and AppHang81 errors isn’t terribly helpful. From what I can tell, this happens sometimes and may or may not be fixable using standard troubleshooting techniques:

• Apply pending updates
• Run System File Checker (sfc/scannow)
• Disable Third-Party extensions (NirSoft ShellExView is a common culprit)
• Try a clean boot
• Check Event Viewer for more details

If the error kept recurring, I might be inclined to go to such lengths. But over the entire ReliMon window (30 days) it’s happened exactly once, 10 days ago. I’ll keep an eye out. If it happens again, or starts to repeat, I work my way through that standard sequence. Right now, I’ll treat it as a one-off and scratch my head.

Looks like I need to remember to don the old reading glasses when trying to decode fine-print info like ReliMon’s error details. I’ve got the screen jacked up to 125% magnification but sometimes, that’s not enough. Is this the OS’s way of telling me that Windows 10/11 is “no country for old men?” I hope not…
