Any best practices to follow here? Thank u in advance. If the person is an admin it can be very useful This run once line ran gpupdate, displayed the user info, restarted the machine in 5 min, ran a program and a batch file in one line. A 'runonce' script is a file that is run from the 'runonce' section of the Windows registry. The format is a.bat file that has lines of code to run a program only once. For instance, you may want to load a program the next time a user logs into the computer. The file runonce.exe is located in the C: Windows System32 folder. Known file sizes on Windows 10/8/7/XP are 50,688 bytes (63% of all occurrences), 48,640 bytes, 34,816 bytes or 36,864 bytes. The runonce.exe file is a Windows system file.

After many hours of doing my own research, I stumbled across the solution that worked for me.
The first answer was sort of correct. Prior to 10, Windows would run the RnOnceEx commands synchronously. This has now been changed to asynchronously which means the Explorer shell can run when it wants to, instead of after the RunOnceEx commands/keys have completed, as confirmed in this article, which is also where the answer lies -

Therefore, you need to add the following reg key - reg add HKLMSoftwareMicrosoftWindowsCurrentVersionExplorer /v AsyncRunOnce /t REG_DWORD /d 0 /f
While the article states to add a line to your Unattend.xml file, I like to do this old school. My Setupcomplete.cmd file calls up my reg tweaks in a separate file using the following -
[HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorer]
'AsyncRunOnce'=dword:00000000
I also run the disable animation tweak as that really bugs me too!!!
