How to find out if an MSI I just installed requested a Windows reboot?

I've built a setup.exe in C# that runs several chained MSI's (with the /QUIET /NORESTART). At the end I'd like to check if a reboot is needed in the machine (that is, if one of the MSI's requested a reboot).

How can I detect so?

Solution

  • The following registry location has the information:

    Key HKLM\System\CurrentControlSet\Control\Session Manager, value PendingFileRenameOperations
