Windows 10 - This app can't open

Recently, I've had a spate of requests revolving around Windows 10, and Outlook attachments with Windows Apps. Photos, Edge, etc.

When a user tries to click on a web link, or open an attachment from Outlook when a Windows App is the default application, it throws the following error.

To resolve this, type UAC in  Cortana and click on Change User Account Control Settings
Change this setting to something other than Never Notify

 Once you've made that change, open Local Security Policy and browse to Local Policies > Security Options.

Change User Account Control: Allow UIAccess applications to prompt for elevation without using the secure desktop to Enabled

Restart the computer, and everything should be working fine again.

Event ID 1058 - The processing of Group Policy failed

After a Windows Server 2003 Standard R2 to 2012 Standard R2 migration, I ran into some Group Policy issues.

This site only one one policy, which was a Group Policy Preference for mapped network drives.
Windows 7 machines worked fine. The 2012 R2 servers and Windows 10 workstations on the domain were not working.

Performing gpupdate /force on the affected workstations returned the following.














Similarily, the error returning in the System Event log was identical.

It turns out there was a few non-confirming changes made to the default domain policy, when the 2003 was the PDC. I had to reset the default domain policy to default, with the following tool dcgpofix on the new PDC. After a reboot of the workstations, everything was functioning well.
