FAQ

Question:
Can I modify this script to add a pop-up for a user to schedule their own reboot?
Answer:
No, User-Prompt Show and prompter are written for PowerShell v5 or above.

Question:
Is there anything the end user will experience due to running this script?
Answer:
Yes, if a user is logged on to the computer while this script is running, they will see an alert pop up in the bottom right-hand corner of the screen informing them that there is an important update that requires a reboot to complete. A yellow-bordered pop-up may appear requesting a reboot, which can be granted or postponed.

Question:
The script keeps failing on this machine, why?
Answer:
You should be able to see the reasons why the script failed in the script logs for that machine. You can expect script failures if any of the following conditions are true, and the log will reflect this.

This script will not update if any of the following conditions are true:

1. Target OS is Windows XP, 2003, or Vista/2008, because PowerShell V5 is not available for these operating systems.
2. Target OS is Windows 10 or Server 2016, because PowerShell V5 is installed by default on these systems.
3. Target OS is Windows 7 or Server 2008R2 but not SP2, because SP2 must be installed to install PowerShell V5.
4. Target OS is Windows 8, because PowerShell V5 is not applicable to this operating system.
5. Target OS is Windows 7 or Server 2008R2 SP2 but missing .NET Framework 4.5.2 or greater, because .NET 4.5.2 is required.
