winreg.SetValueEx can create the value. We just need to add a case to test_case in Lib/test/test_winreg.py, such as the following:
("Multi-nul", ["", "", "", ""], REG_MULTI_SZ)

Do you mean a variation of MOVEFILE_DELAY_UNTIL_REBOOT that doesn't require administrator access? That would be useful if it existed. I suppose a MOVEFILE_DELAY_UNTIL_LOGOFF flag could be added to have the logon process (winlogon.exe, instead of smss.exe) perform the delete/rename operation under impersonation at the end of the session, or (given a system crash or power failure) the next time the user logs on.
