Windows 11 on Unsported Harware Not Getting Updates
Hi, I trust someone can help. I have unsupported hardware, no TPM or secure boot. I used the Rufus method to update Windows 10 Pro to Win11 (24H2) in January 2025. All worked well until fairly recently updates failed to install i.e. "Windows 11, version 24H2 (repair version) Failed to install on 14/01/2026 - 0xc1900200".
When I try to fix this I get the message that I have unsupported hardware.
I have just used the enablement package (KB5054156) and successfully updated from 24H2 to 25H2. However when I check for latest updates this still fails and get the same message that my hardware is unsupported.
Can anyone suggest how I can solve this to successfully get updates. Would doing an "in place" install using the Rufus method sort this problem i.e. reinstalling 25H2 over the existing 25H2?
All help gratefully received.

Your system's hardware isn't officially supported for Windows 11, which causes update failures. While you've managed to upgrade using special packages, Windows Update still refuses to provide updates because it recognizes the hardware as unsupported. Doing an "in-place" reinstall with Rufus or similar tools might help, as it can sometimes reset hardware checks and allow updates to proceed smoothly.
