Windows Pop up - Do you want to allow the following program to make changes to your computer

One of the annoying pop-up in Windows

"Do you want to allow the following program to make changes to your computer"

This alert pop-up everytime I open a word document, whether the answer is yes or no, the pop up continue with another " There was a problem sending the command to the program".

Fix:

Firstly, verify that Word isn't being automatically started within Admin Mode
Right Click on the word exe file ->Properties->Compatibility Tab->Privilege Level. 

Check Run as Administrator is unchecked.

If it already is, or this doesn't rectify the issue, check Microsoft Office Compatibility.

1. Open Microsoft Office Properties
2. On Compatibility Tab, check the Compatibility mode is set to your operating system. Mine by default is set to Windows (SP3). Change to Windows 7
