Install error - 0x800f081f for Windows 11, version 25H2 via Windows Update
As per title. Tried Windows Update numerous times to no avail.
Tried a few YouTube recommended fixes with no success.
Downloaded the so-called ISO file that seems to contain no ISO file, just a 'setup' file that I can click, but since the first option to 'Keep personal files and apps' is for some reason greyed out, I can't use that...
Also the Windows Update Diagnostic fails to run.
What a product.

The 'Keep personal files and apps' option is greyed out, when there is language mis-match between installed language for Windows 11 installation and ISO file language. You need to use same language ISO file, then only you can keep your data while upgrade.
Let Windows try to fix the problem automatically first.
Open Settings (Windows + I).
Go to System > Troubleshoot > Other troubleshooters.
Click the Run button next to Windows Update and follow the prompts
Always back up your data before performing major repairs or clean installs.
Use the Windows 11 Installation Assistant or the Media Creation Tool to select “Upgrade this PC while keeping your personal files and apps” to bypass Windows Update installation errors.
