I got a 2in1 Dell Laptop. I did a clean install of a Dell issued copy of Windows 10 Pro after a SSD change. After an immediate subsequent upgrade to Windows 11 Pro I had the same issue.
I coudn't disable the checkboxes. I couldn't switch to compact view. I checked the registry keys - they all were set correctly. But as it is a tablet mode issue I circumvented the problem.
For everyone who uses a 2in1 and uses it as laptop try the following:
- Open Registry Editor
- Go to Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ImmersiveShell
- Set DeviceConvertible to 0
- Sign out and back in to your account
Voila, no more checkboxes and compact view also works. This cost me 3 hours of my day. By now I can send Microsoft an invoice for 100s of hours of unpaid work due to their bugs...
