Windows 10: Scaling changes to 100% after restart or sign out

I have an Alienware X17 R2 running on Windows 11. I set a custom scaling to 115% as 100% is too small and 120% is too big for me. So I set a custom scaling which is 115%. However, this issue happens and it is the first for me. Whenever I restart or sign in into my PC, the scaling stays at 115% and shortly it reverts back to the fixed scaling which is 100% Notice how the desktop becomes messy as it reverts back to 100% and I am really frustrated over this. I installed latest graphics driver, still it doesn't work. I'm wondering if this happens on the Alienware software's end. Attached below

When un-docking laptop, Windows scaling changes to 125% but still shows 100% in settings

I have a 1920x1080 laptop display, and 2 extnernal 1920x1080 displays. When I dock, I do not use my laptop display. Scaling is set to 100% for all monitors when in use.

When I un-dock, and open my laptop display, scaling changes automatically, and visually appears 125%. I go to my display settings, and it says 100%. But when I change to 125% (which is the "recommended" setting) then back to 100%, my display then looks as it
should.

This is quite repeatable.

• I would prefer scaling does not change when I un-dock
• Why does does he actual scaling not match what the setting is set to?

 

Windows 10 Creator's update - Every time I undock, scaling goes to 150%

We appreciate that you have checked your drivers and followed the suggested troubleshooting steps. Since the issue is still the same, this can be related to the new customer scaling settings that came with the Creator's Update. Can you follow the steps below
so we can check it for you:

• Click on Start then Settings.
• Choose System then Display.
• Under Display, select Custom scaling and set it to 100%.

Update us on how it goes as we are eager to get this resolved for you.

 

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.
