Hi Mo,

I ended up getting a response from MS.

Log on one Windows 1703 client.
Run regedit.exe, locate key HKLM\Software\Microsoft\Windows\CurrentVersion\FileAssociations\UpgradeChoice (if the key does not exist, create one with the name.)
Create a DWORD value named AppUpgradeVersion, set it to 2.
Migrate a user to this client.

I still had issues with associating PDFs with Adobe Reader, but MS came back and said that it was an adobe issue.

Hi Dale

Thank you for the tip it worked!!

BTW Im doing all this on the 1709 version.

I applied the reg key in the re-image task sequence, and user data is restored during the task sequence. When the user logs in file associations are all OK.

I did notice if a re-image is done on the same PC again, and if user data is captured then restored, the file associations break again.

If the key you mentioned exists on the PC before a user logs in, then the same key then gets created under

HKCU\Software\Microsoft\Windows\CurrentVersion\FileAssociations\UpgradeChoice

This causes the file associations to break on a capture and restore.

If i delete HKCU\Software\Microsoft\Windows\CurrentVersion\FileAssociations\UpgradeChoice before the capture then its works again.

Did Microsoft explain why this is required? As you mentioned before trying this the ApplyOnUpgrade and OverwriteIfProgIdIs didnt help either.

I also noticed on a 1709 Pro version, non Domain joined PC the HKLM and HKCU keys already exist.

Thanks again for all your help

Mo
