Default Applications won't stay set
In some image versions, users were not permitted to change the default browser from IE to Chrome, this is because CYSIS didn't support Chrome years ago.
If the user complains or the user encounters an error opening links from Outlook, do the following:
Run MMC.exe as administrator
Add Group Policy Extension for Local Computer
Under Computer Configuration
> Administrative Templates
> All Settings
> Sort by "State"
> Set "Set a default associations configuration file" to Disabled
Close MMC
Delete C:\Windows\System32\Appassoc.xml
Reboot
Set Google Chrome as default
Links in Outlook will work.
