Hallo,
I’m using W10 version 21H1 Build 19043.2251 on standalone desktop. Recently I noticed that clicking on any of the Office 2016 pictograms does not open the program any more. Also double clicking directly on an Office file does not start the associated program any more. The only way to start an Office program is to start the program by “Opening it as Administrator”. Opening an Office file is only possible by first opening the associated program as an Administrator and then opening the program. Needles to say this is very inconvenient.

My personal local account is set to Administrator but it seems as if my administrator privileges are recently restricted somehow. Could have appended after an software update, but I’m not sure about that. Recently I also noticed that my desktop is offering a choice for starting up as The Administrator and my personal account.

On the Internet I read some vague posts, that this could have to do with Windows Defender Application Guard sometimes restricting privileges. I also somehow managed to find something in Windows Powershell, showing that my privileges are indeed restricted. However stupid enough I lost track how I got there.

Does anyone have an idea how I could bring my desktop back to its normal behavior?

Regards,
Dave
