Hi Michael, Setting them using an xml file is one solution, and it is useful including the process. Thank you.
However, as it’s an option available during manual install, I’d have thought it would be an easy option to configure during the silent install. I’m not sure how the manual installer does it (whether it mimics the manual key and mouse clicks or uses a more efficient method). While it seems to have been an option in the older installers, those solutions don’t seem to work anymore. I’d hoped I was missing something, but it seems from the responses there isn’t an easy way of doing it.

You also cannot simply set a default application and then copy the RegKeys to another machine, it does not even work for other users on the same machine. The checksum includes the machine name, user name and the application. Microsoft wants to prevent malware to change those settings, I assume. And they do want that the users change defaults on their own, which is bad for administrators. But Windows 10 has a new GPO for setting default file associations. You set them on one machine, export it to an xml file, edit it manually if needed (you may remove the lines for applications that you do not want to change as those are already default) and then give the path to the xml file in the GPO. The xml file may be on a network share (e.g. NETLOGON), or copied by SCCM during install to the machine (local C: path). You need cumulative Windows update from December in order to correctly work at the very first logon of a new user (before it only worked on second logon and later, or restart of explorer.exe process). This is tested with Windows 10 1607 LTSB. This way, I set old Windows Picture Viewer as default app for several picture file types, change the default browser from Edge to IE and set our pdf application as default for pdf. I do not know what some programs do that offer to register themselve as default application. Do they send key/mouse commands to simulate manual user interactions (so fast that you do not realize it), or is there another way (I did no way by my own internet research)? Regards, Michael
