Has anyone else hit a constant "This PC can't run Windows 11" message during the upgrade check? My laptop meets all the official requirements (TPM 2.0, secure boot, etc.), but it keeps failing. I also got a vague error code 0xC1900101 a couple times before it reverted to Windows 10. I've run the update troubleshooter with no luck. Any ideas on what I'm missing or how to fix this?
I ran into this a while back. That error code often points to a driver conflict. I'd try doing a clean boot and then running the upgrade again to see if that isolates the problem.
Can confirm. You could also try temporarily disconnecting any non-essential peripherals, like external drives or docks, before starting the upgrade again.
+1 Agreed, that driver fix worked for me too. A quick tip: also try temporarily disconnecting any non-essential USB devices before running the upgrade again.
