Application compatibility soft blocks refer to the warning dialog you see when attempting to run or install applications with known issues. The Citrix ICA client is a great example, the dialog looks like this:
If you have tested the application and found that it works for your scenario, you may wish to hide this dialog. It’s potentially confusing for users and therefore a help desk call generator. There is a group policy setting they may use to disable all soft blocks – but it’s preferred to remove the warning for specific apps known to work. To do this:
Take a before snapshot of HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags
Open the application
Select Don’t show this message again
Click Run program
A new value has been added to HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags
(for Citrix 9 it’s "{d3869258-b773-4101-8abc-30928314c3b2}"=dword:00000004)
That value can be deployed in the image (or other method) to this location:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags
The soft block is now effectively disabled for this application.
