Whilst repaving my Lenovo W520 I had some issues with video cards. During the initial setup of Windows the PC hung. I rebooted, re-enabled in the BIOS the problematic video card and I thought all was OK. The installation appeared to pickup where it left off. However, I started to get some very strange problems.
- My LiveID settings did not sync from my other Windows 8.1 devices
- I could not change my profile picture
- I could not change my desktop background
- I could not change my screen saver
- And most importantly Windows Update would not run
I found a few posts that said all of these problems could be seen when Windows was activated, but that was not the issue for me. It showed as being activated, changing the product key had no effect.
In the end I re-paved my PC again, making sure my video cards were correctly enabled so there was no hanging, and this time I seem to have a good Windows installation
