Right, but I can't see if the lock screen image is mine or the default Windows image until I restart.
Because that would close all running programs including the Macrium Reflect full backup which is currently running.

EXITNot a fix, but I was able to find a workaround. I just take over ownership of the C:\ProgramData\Microsoft\Windows\SystemData folder and go in the user ID folder there and copy the name of the stupid blue windows lock screen in LockScreen_Z and paste int onto a copy of the picture I use for my current lock screen, then copy and paste that image file over the windows one. It works but it's a pain, you have to take over ownership after each log on or restart, and you have to change the image file every time you want to change your lock screen (so it matches the one in account personalization). And do not delete any of the LockScreen folders in there. I made that mistake and it completely refused to see any of those images ever again, even through user personalization. I recovered them from the recycle bin and restored them. Windows 11 has looong tiny little fingers in literally everything.
Makes sense. I actually did not have this issue until I enabled Secure Boot in my BIOS. I saw some windows error logs saying it couldn't communicate or write rules to the BIOS because secure boot was off. It wrote and spoke to the BIOS just fine after that- a little too much LOL
I assume I have to run this in Powershell? Windows gives me a warning that pasting this code could execute actions with negative consequences. If something bad does happen, can I restore the system by rolling back to my latest Macrium Reflect backup? Also, should I do a registry backup prior to executing the code?
