Although winget exists on your system, but when you try to run the winget with system account (or using the scheduled task with the system account) and you see this error.

winget : The term ‘winget’ is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Most Common WSUS Errors Codes

If you encounter Windows update error codes, you can check the System log in the Event Viewer, typically under the event source “WindowsUpdateClient” (though it doesn’t provide much info as always 😂). Another place to look is in the “C:\Windows\Logs\WindowsUpdate.log” file for Server 2012R2 / Windows 8.1 and below. For the later Windows version, you will need to use Event Tracing for Windows (ETW) to generate diagnostic logs.

Powershell Script for Day-to-Day Active Directory Operations

Hi fellow scripters, I’m pretty sure this handy script will help system admins to make a day-to-day AD operation super easy. You can quickly jump into the screenshots to get an overview idea. Note that Powershell module for AD is required for this script.

Things to note:

By running this script, all users/groups in the text file or all child users/groups under the defined OU will be affected. So, make sure you are completely aware of the explanation of parameters you want to do with the script. The suggestion is to test on your non-production systems first.

Set Any Attribute of AD users by using PowerShell Script

Updated Post: Now, instead of the SamAccountName you need to use Identity in the csv header to identify users (which is the existing SamAccountName of users).
