Windows Upgrade Help and more

Can confirm. Yeah, that's a common snag with the 7th-gen Intel chips. You can try the Windows 11 Installation Assistant directly from Microsoft's site—it sometimes bypasses that block.

Yeah, and if you're still stuck, try clearing the TPM from within Windows security settings before running the check again.

Yeah, that's a known thing. The 7700K is actually just below the cutoff—Microsoft requires 8th Gen Intel or newer for the official upgrade path. There are unofficial workarounds, but they aren't supported and can be a bit risky.

Same here. I had the same problem. I had to go into my BIOS and manually enable both TPM and Secure Boot, even though the checker said I was ready. Hope that helps.

+1 You could also check if there's a BIOS update for your motherboard, as that sometimes adds TPM support for older chips.
