Problem/Question
On a Windows 10 computer, I have changed my PDF tool to something other than Adobe Pro, but after rebooting, it changes back to Adobe Pro
Overview
In an attempt to standardize the tools ADS uses, this setting has been configured on the local group policy level.
Solution
Open gpedit.msc - Computer config > Admin templates > Windows comp > File Explorer > "Set a default associations configuration file"
The configuration setting is Enabled, you will want to set to Disabled.
