Admin but not.
Navigate to: C:\Windows\System32\Taskmgr.exe. Right-click the file, select "Properties," then click on the "Security" tab. Verify the following settings are enabled: ALL APPLICATION PACKAGES -> Read & Execute + Read ALL RESTRICTED APPLICATION PACKAGES -> Read & Execute + Read SYSTEM -> Read & Execute + Read Administrators -> Read & Execute + Read Users -> Read & Execute + Read TrustedInstaller. Ensure Full Control is selected and Modify is enabled. If correct, type "netplwiz" in the Windows search bar, press Enter. A window will appear where you can adjust settings and then log back in or restart your PC. If you're using Windows 10 Pro, please let me know.
It is Pro, and I plan to test it today. Also, sfc detects corrupt files, but it can't repair them.
ok very good. What I wanted to add for you to check: Under netplwiz panel, go to the "Advanced" tab, and then inside, hit the "Advanced" button A panel will open, with 2 folders "Users" and "Groups". First, double click on "Users" then double click on your account, to get another panel to show up. Go to the "Member Of" tab, and make sure that "Administrators" (with an 's' at the end) is there. If it looks good, you can close this panel, and now navigate to "Groups" on the previous panel. Then double click on 'Administrators' to get a panel to show up, and make sure that you have "Administrator", and your account name showing in the box in the middle of that panel. If all good, close it, and then pick "System Managed Accounts", and see if you have "DefaultAccount" only listed. If yes, good! Don't touch, and close. Then lastly, double click on "Users", and make sure you have only 2 entries: "NT AUTHORITY\Authenticates Users (S-1-5-11)" and "NT AUTHORITY\INTERACTIVE (S-1-5-4)" Of course, like before, any changes, requires that you logoff and log back in, or restart your system to take affect.
I really wish the recommendations would resolve this for the user. What’s your perspective on how this could occur? Did they experiment with permissions, or is this a genuine issue? Also, the fact that the OP mentioned a virus scan performed a long time ago raises concerns for me—it definitely feels like a potential sign of malware activity. While it’s possible a virus could cause such behavior, it seems more likely something malicious was involved, especially if admin access was compromised. I hope adjustments to permission settings can address this, but I’m curious about the real reasons behind it.
