Sure why not here is the steps:
Install Acrobat and don't make any changes.
Export the Registry settings from HKCU\Software\Adob\Adobe Acrobat\11.0 call the file beforechanges
Make changes in Acrobat
Export the Registry settings again from the same location call the fall after changes
Then run this in powershell
Compare-Object $(Get-Content c:\beforechanges.reg) $(Get-Content c:\afterchanges.reg)
Then the output will look like this:
Input Object SideIndicator
iFormat=0001 =>
iFormat=0002 <=
Side indicator is which file it's in => is the right one in the compare object and <= is the left one.
So we can see that the iFormat key was changed from 2 to 1 after we made some changes.
Yes I know that's not the right regkey for the iFormat just an example.
