Windows Upgrade Help and more

That error code often points to a driver conflict. I'd check for any pending BIOS updates from your motherboard manufacturer and make sure all your chipset drivers are current.

Did you check if there's a pending BIOS update for your motherboard?

Has anyone else had the "This PC can't run Windows 11" error, even though my PC meets all the requirements? The Health Check app says my TPM 2.0 is enabled and Secure Boot is on, but the upgrade assistant still fails with error code 0xC1900101. I've tried the installation three times now and it always rolls back. Are there any recovery options to try, or do I just wait for a future update? Really hoping to avoid a clean install.

Can confirm. You could also try using the official Media Creation Tool to do a clean install instead of the upgrade path. Another option is to check if any specific drivers, especially for storage or chipset, need updating before the attempt.

Yeah, sometimes a specific driver is the culprit—have you checked for any optional updates in Windows Update, especially for your chipset or storage? Let me know if that works.

Thanks! I found a BIOS update, but I'm nervous about installing it. Is there anything I should do first to avoid messing up my computer?

Same here. I had the same problem. Updating my BIOS is what finally fixed the 0xC1900101 error for me. Good luck!

+1 Yeah, a BIOS update is a common fix for that—did you also check if your drivers, especially chipset and storage, are all up to date?

You could also try temporarily disconnecting any non-essential peripherals, like extra monitors or USB devices, during the upgrade. Good luck!

Same here. I had the same problem—it turned out a BIOS update I hadn't installed was the final hurdle.
