Hi Guys, I have a failed update KB5066835 tried a couple of times and got the message 'reinstall windows' as per the shot below....
My question is will clicking the reinstall do it all automatically or am out of my depth as a 'complete novice' in this area. Would it be better to click the version 25H2 install button?

Edition Windows 11 Home
Version 24H2
Installed on ‎14/‎02/‎2025
OS build 26100.4652
Experience Windows Feature Experience Pack 1000.26100.128.0

I have this problem too few days ago, so I try use 'Fix problem using Windows Update'
It fixed my Windows issues and no issues after using 'Fix problem using Windows Update'
Can you try 'Fix problem using Windows Update'

Thanks I'll give it a go, can you tell how long it took please?

Hopefully I'll be back and say it worked!

Using the Windows Update fix downloads the entire OS image, not just the CU.
Depending on your internet & system performances, it can take up to 2 hours.
