Ah thanks. I thought this build number still counted as 20H2, because the table at Find Windows 10 Version Number | Tutorials (tenforums.com) shows that the next build, 21H1, starts from 19043.928.

Windows update shows the following update is available:

2022-01 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB5009543)

but every time I try it, it gets to 100%...

I can't even install PSQlite!

I broke the Apps by messing with the folder permissions to see the game files I'd installed on a secondary SSD because I wanted to see how much space was...

I can't type it in on the new PC to activate it though can I?

Those tutorials seem to apply to deactivating and reactivating a retail product key on a new PC, which isn't applicable here as my Mum has a digital licence. I imagine if I deactivate the licence on...

Hi, thanks for the tip. The screenshot is attached and says Retail so it looks like it should be transferable.

To answer your other questions:
I'm signed in on both PC's using the same...

It doesn't say reactivation is limited to replacing the hard drive. It says replacing your motherboard, which is basically the entire PC, and she won't be using the old PC once I transfer her SSD and...

The new PC is secondhand with a clean install of Windows 10 but as her Windows 10 licence is linked to her MS Account I understood that this allowed her to reactivate if she changed hardware. I'm...

I got my Mum a new PC to replace her current one as it's been having some hardware issues. I changed her from a local account login to using her outlook.com account and that's fine but it doesn't...

Thanks. Yeah, I'll make sure he's got up to date system images and a recent System Restore point and a backup of the BCD.

Thanks jdc1, I've got TeamViewer access to his PC. Normally I'd be able to go over there to fix stuff as he lives nearby but obviously I can't do that at the moment.

I use grub4dos myself and...

My Dad runs a dual-boot Win 8 / Win 10 system. He uses Win 8 most of the time and Win10 is just for his flight sim, which he doesn't have a lot of time for so he doesn't boot into that very often.

Also a few weeks ago there was only 181MB free on the C: partition, which probably explains a lot of those errors in the logs. There's around 20GB free now but I'll try and clear some more to allow...

Thanks, here's the first set of results. I'll post the remaining SSD tests when they're done.

Thanks. I think I'd already disabled Fast Startup but I've done it again to make sure.

System Restore is already disabled, Storage Sense is enabled and I have installed Macrium Free.

I've...

My Mum's sent me a video of her Windows 10 PC booting and what appears to happen is the first time it loads the blue recovery screen which says "It looks like Windows didn't load correctly" and then...

Thanks dalchina

EDIT: OK. The script just finished as I was typing this, so I guess it just takes a while to update the group policies. I'll try the Update again now. /EDIT

I've run that script...

Windows update prompted me to "Download and install" the 1903 update. The first few tries it kept failing at 5% but I read that battleye could cause it to fail and although I didn't have that...

Thanks for the suggestion but I prefer ThrashZone's solution as there may be some other non-Microsoft drivers that it would be good to receive updates for.

Thanks, that did the trick.

Every time I check for updates (I've disabled automatic updates in Group Policy) it downloads and installs this driver "Conexant - MEDIA 7/3/2018" which seems to be for the laptop's soundcard.

How...

Yep, that seems to have done the trick. Now right-clicking on the taskbar icons works, as does clicking on the search bar, the Windows Defender Security Centre window opens now, as does the Add new...

Thanks but that didn't help. Literally nothing happens still when I right-click on tasbar icons.

I see a lot of errors in Event Viewer for the Windows logs - Applications relating to various...

Thanks but the slow boot problem was fixed by a scan/repair.

I just ran InSpectre and it shows Yes, Yes, Yes, Good (not sure how my system is protected as I haven't updated the BIOS recently....

I run a dual boot Win 8.1 and Win 10, with the latter just for gaming which I haven't had much time for recently, so I haven't booted into it that often. So when I did a month or two ago there were a...
