Ugh, so mad. Trying to upgrade to Win 11 for ages. My PC runs fine! It’s got thi

Same here. Yeah, that CPU is just barely outside the cutoff. A small tip: you can still do a clean install with an ISO, but it's not officially supported.

This. Yeah, that workaround can be messy though—have you double-checked if TPM 2.0 is actually enabled in your BIOS?

Agreed. Yeah, and that specific Pentium model is unfortunately on Microsoft's official unsupported CPU list, so even with TPM 2.0 it'll likely still block you.

Yeah, it's a real bummer. A small tip: you can still do a clean install with an ISO, but you'll lose official updates and security support.

Same here. Have you double-checked if TPM 2.0 and Secure Boot are enabled in your BIOS?

I had the same problem. That exact CPU isn't on the supported list, so no amount of BIOS tweaks will get the official upgrade to work.

Yeah, it's a real bummer—have you looked into the registry bypass workaround, or are you sticking with Windows 10?

This. That bypass is a bit risky, so if you go that route, just be sure you're okay with no future updates.

Yeah, Agreed, and one more thing—if you do bypass it, make a full backup first just in case.

Yeah, and honestly, if you're still on Windows 10, it's still getting security updates until late 2025, so there's no huge rush. Hope that helps.
