To add a user to the Hyper-V Administrators group, you must already have administrative privileges on the host machine. This process allows standard users to manage virtual machines without giving them full system administrator access.
(Replace “UserName” with the actual account name or “Domain\UserName” for domain accounts).
Option 2: Use Command Prompt
Run Command Prompt as an Administrator and use this syntax:
cmd
net localgroup “Hyper-V Administrators” “UserName” /add
Note: Group names are localized; if your Windows installation is not in English, use net localgroup to find the exact name of the Hyper-V group on your system.
Option 3: Use Computer Management (Graphical)
This is the most common method for Windows 10, 11, and Windows Server users.
If you paste this into admin powershell, it disables copilot inside of MS365 installed apps. Doesn’t change apps online, or the ability to use other AI’s, even copilot website, BUT it does block the copilot add on items in all installed office apps (Being used for PCA here shortly)

Hide a Local User Account from the Sign-In Screen in Windows 11 by GUI or by Powershell Admin/Script
Overview
This guide explains how to create or use a local Windows 11 user account while hiding it from the login screen, so that the account remains active and accessible (by name/password), but does not appear among visible users at sign-in. The script near the end after the GUI steps will make this faster.
NOTE: The script is untested as of 6-20-25 because I don’t have time but from the looks of it seems pretty good. Definitely test on a throwaway vm before deploying the script please. – Andrae
This will be good for hiding the Scanning user especially, attention raised from Tavros #3583 where staff was concerned about having this extra user installed for no clear reason. We can use this to hide service accounts as needed so it doesn’t become a concern for anyone that might be a little more tech-fearful or just wants more cleanliness.
🔒 Who This Is For
Administrators creating service, support, or maintenance accounts.
Users who want to keep an account functional but discreet (not visible to regular users).
✅ Requirements
You must be logged in with an administrator account.
Be comfortable using the Registry Editor (regedit.exe).
👇 (Optional) Backup your registry or create a System Restore point.
The specified user will no longer appear on the Windows 11 login screen, although the account is still active with its password intactwintips.org+1umatechnology.org+1.
🔄 Unhide or Re-enable an Account
To undo, open the same registry location and either:
Account remains usable: Users can still log on if they manually type the account name and password (e.g. via `Ctrl+Alt+Del ➜ “Other User”)superuser.com+20xjamesli.com+2wintips.org+2.
Does not increase security: This is an obscurity measure, not real protection—admins with registry or local privileges can still see and modify hidden accounts.
Let me know if you’d like screenshots, automation scripts, or batch commands to make this process even easier!

A powershell script to do this even quicker would be awesome if you’ve got it.

Here’s a PowerShell script that automates hiding (or unhiding) a local user account from the Windows 11 login screen by updating the registry:
powershellCopyEdit<#
.SYNOPSIS
Hide or show a local user account on the login screen (Windows 10/11).
.PARAMETER Username
Name of the local user account to toggle.
.PARAMETER Hide
Specify $true to hide the account, $false to show (or remove) it.
.EXAMPLE
.\HideLocalUser.ps1 -Username "ServiceAccount" -Hide $true
#>
param(
[Parameter(Mandatory)][string]$Username,
[Parameter()][bool]$Hide = $true
)
$regPath = "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList"
# Ensure the key path exists
if (-not (Test-Path $regPath)) {
New-Item -Path $regPath -Force | Out-Null
}
# Set DWORD to 0 to hide, 1 (or delete) to show
if ($Hide) {
New-ItemProperty -Path $regPath -Name $Username -PropertyType DWORD -Value 0 -Force | Out-Null
Write-Output "✅ '$Username' is now hidden from the login screen."
} else {
# Option A: Set value to 1
if (Get-ItemProperty -Path $regPath -Name $Username -ErrorAction SilentlyContinue) {
Remove-ItemProperty -Path $regPath -Name $Username -ErrorAction SilentlyContinue
}
Write-Output "✅ '$Username' is now visible on the login screen."
}
📌 How to Use
Save the above script as HideLocalUser.ps1.
Open PowerShell as Administrator.
Run to hide:powershellCopyEdit.\HideLocalUser.ps1 -Username "YourUserName" -Hide $true
Or run to unhide:powershellCopyEdit.\HideLocalUser.ps1 -Username "YourUserName" -Hide $false
