Windows Upgrade Help and more

Thanks! I found some RAM, but now I'm getting an error about "TPM 2.0" when I try the upgrade. What does that mean?

Perfect solution, thanks!

I’m trying to upgrade from Windows 10 to 11, but the PC Health Check app says my PC doesn’t meet the RAM requirements. I have 4GB installed, which runs Windows 10 fine. The error code I get is “This PC doesn't meet the minimum system requirements.” Is 4GB really not enough, or is there a workaround ...
