How to stop Windows 10 Continuous Prompts to associate a Viewer for PDF Files

If Windows 10 keeps prompting you to associate an application to view PDF files when you double click to open them, try deleting the following registry keys and rebooting. This worked for me.

1. Open regedit as an administrator
2. Navigate to Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.pdf and delete the .pdf key
3. Navigate to Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\FileAssociations\ProgIds and delete the REG_DWORD called _.pdf
4. Reboot

This reset the default to Microsoft Edge and then allowed me to change the default to Adobe Reader.

Intel Graphics 5th Gen Windows 10 Driver Disabled Fix

Windows 10 will disable the Intel(R) HD Graphics 5500 or similar GPU drivers if Hypervisor Code Integrity (HVCI) is enabled. HVCI appears to be enabled as part of Hyper-V. This affects laptops from all vendors as far as I can tell.

To disable HVCI,the registry entries outlined by Microsoft do not appear to work.

Microsoft does however provide a PowerShell script which does work.

1. Download the script from the link above
2. Extract the script
