Windows 10: How can I sign into windows pro 11 with my work email when I keep getting an error it's not...

I've purchased a windows 11 pro OS and installed it on the machine. During the windows out of box experience, it wouldn't recognize my email. The email is my work email as I'm a small business. The user name and password work on both Azure and Microsoft 365. I used my personal email to set up a profile and tried to add an account through settings. When I go to the add an account in settings, it doesn't provide me the option to join an Azure ID or sign into Microsoft 365. I'm trying to avoid keeping any personal profiles off this computer and have this be fully synched with Azure and 365. What

How to troubleshoot an error that appears only at Restart or Sign out?

I get an error pop-up error message not every, but almost every time I Restart or Sign out. It's the screen with blue background and on top of Restart or Sign out text an error window says:

Explorer.exe - Application error. The instruction at 0x000… referenced memory at 0x000... The memory could not be written.

Sometimes the error code is just zeros, sometimes random numbers. I have tried so much already to troubleshoot this. For example these did not help in any way:

• MemTest86+ (no problems)
• Disabling any Services, Autoruns/ShellExView entries
• Low resolution mode
• BIOS settings are fine, no overclocking etc.
• DISM.exe and sfc
• etc.

However, these do make the error go away:

• End process for explorer.exe before Restart or Sign out
• Safe Mode
• Creating a new user profile (almost the same as clean installing Windows, many full days of work)
• Uninstalling NVIDIA graphics driver (then the card is unusable, of course)
• Disabling Device Manager / Display Adapters / NVIDIA GeForce GTX 1080

I already contacted NVIDIA and the graphics driver is not the culprit. Something has gone wrong with the user profile as the same driver works just fine in a new profile (and there's nothing wrong with the driver anyway, it's just the Restart or Sign out process that has a problem).

What can I do to fix this? One useful thing would be to have a step-by-step procedure for the Sign out. So that it'd ask before continuing to the next step and list what it's doing. Or if I could just disable whatever it does when the error appears.

 

Windows 11 Work account Sign in

I got a new PC at work and needed to sign in with my work account but realised it was running windows 11 home, so I signed in with my personal account and purchased the windows 11 pro upgrade through the Microsoft store.

Since this is a work PC I don't want to be signed in with my personal account and linking my work one, but I can't see how I would sign in to my work account besides resetting the PC and doing it there.

Is there is a way to change the primary sign in account to my work one and remove my personal account. If not would resetting the PC remove the windows 11 pro licence and leave me back at step 1?

 

Windows 11 Home to Pro upgrade

Want to upgrade 11 Home to 11 Pro. Tried download, but apparently files transferred were for 11 Enterprise. This will not activate; error is "invalid digital license or product key". This is on a new Surface. How to proceed?

Can withdraw/delete this. The suggestion to downgrade - listed below - with a 'fake' windows 10 key works.
