Windows Upgrade Help and more

This. I had the same problem after the last update. It felt like starting from scratch with all those app permissions. Hope that helps.

Not 100% sure, but I had this issue on an older laptop. Even though 4GB is technically the minimum, the upgrade tool can be picky about available free RAM during the check. Try closing every single app and background program, then run the check again. Let me know if that works.

Yeah, Have you checked if your PC actually meets all the Windows 11 system requirements, like TPM 2.0 and Secure Boot?

Can confirm. Another option is to run the Windows Security troubleshooter, which might automatically fix whatever is triggering the alert.

I had the same problem. I found a BIOS update that finally enabled the TPM setting my PC needed.

Yeah, and once you're done, double-check Secure Boot is enabled in the BIOS too—it sometimes gets overlooked.
