TCC  26.02.42 x64   Windows 10 [Version 10.0.18363.1082]

I wanted to delete an ISO file that I no longer needed, so I did the following;

e:\documents\win98>del "Win98 SE.iso"
Deleting E:\Documents\win98\Win98 SE.iso
TCC: (Sys) The requested lookup key was not found in any active activation context.
"E:\Documents\win98\Win98 SE.iso"
     0 files deleted       1 failed

I checked, and the ISO was mounted as drive G:, so I ejected drive G:, and tried again;

e:\documents\win98>del "Win98 SE.iso"
Deleting E:\Documents\win98\Win98 SE.iso
     1 file deleted

So, all is good now, however, what does the error message;

TCC: (Sys) The requested lookup key was not found in any active activation context.

mean when I could not delete the file?

Looks like something to do with Windows Side-by-Side. Maybe run Disk Cleanup?

Did you look in the event logs ... application and system?

It's a Windows error, not TCC. I believe that particular error is coming from your group policy.
