Hello, do you want to change just the lock screen or also the wallpaper?
I have a script that works on Windows 11 for changing the lock screen and the wallpaper.

Just to clarify, the video is unlisted, not public; only those with the link can view it, just in case a mod.... :)
After this, it will be modified if you only need the lock screen.

A hello, an answer, a thank you are always appreciated.
It's the same thing: not sure we saved time compared to the graphical manipulation, especially since the line
"C:\Users\tech\Downloads\330.png"
is infected: the user is not the same on each workstation, and even if it were, the image file needs to be copied to that location on each PC.
The 2 issues can be resolved quite easily, but by modifying the script to:
%HOMEPATH%\Downloads\330.png
and by copying the image file to the USB drive before moving it, so that either this script can be launched from the USB drive after going to the drive letter and then using %~dp0, or by adding to the script one that identifies the drive letter upon connection.
Otherwise, we will have to copy this image manually and in any case perform the operation 10 times.
Hello,
Thank you for your many responses, but it’s not quite what I’m looking for.
As I said: 10 PCs and 6 sessions per PC (one per day of the week except Sunday).
I was thinking of a .BAT file to run on a USB drive.
- Copy the club logo to C: with the Copy command.
- Set it as wallpaper with: reg add "HKEY_CURRENT_USER\Control Panel\Desktop" /v Wallpaper /t REG_SZ /d C:\01.jpg
- Set it as the lock screen, but I don’t know the command for that???
Thanks if you have any ideas...

Your question is still not very clear.
The username, if it changes daily, is not relevant since it can simply be referred to as I mentioned by %HOMEPATH% for the wallpaper, and the lock screen is a system-wide setting independent of the user.
The first can be obtained as you noted by a REG ADD syntax; for the second, a somewhat convoluted PowerShell syntax was proposed because the result can also be achieved via a REG syntax as indicated here at the bottom of the thread.

Should we have a different image for each day of the week, and this every week of the year?
In this case, the situation will be a bit more complicated; it would be easier to copy once for all 6 images (of course in a folder independent of the user), but we would need to make a conditional statement in the batch on the day of the week to choose the image and overwrite the previous one using REG ADD /F.
Can you clarify what you want to do?
Hello,
what I want to do is put the club's logo on all sessions of all PCs.
For example: on Monday, when a member turns on the PC, they have the club's logo displayed on the login screen and then as the wallpaper. This for all sessions of all PCs.
Thank you.

Repetita iuvant:
Rather ask this question in this forum https://forums.commentcamarche.net/forum/programmation-3
It is generally resolved by a simple batch but launched as an administrator from the key if other screen conditions are not set on the PCs (Windows in the lead...), which is why the classic approach is more towards GPO or a Tweaker like Winaero Tweaker set up on each PC.
I'm not sure that the lock screen format must necessarily be jpg, in which case the image will need to be copied in 2 different formats.
@echo off IF NOT EXIST C:\mon_image.bmp COPY mon_image.bmp C:\mon_image.bmp reg add "HKCU\Control Panel\Desktop" /v Wallpaper /d "C:\mon_image.bmp" /F RUNDLL32.EXE USER32.DLL,UpdatePerUserSystemParameters ,1 ,True reg add HKLM\Software\Policies\Microsoft\Windows\Personalization /v LockScreenImage /t REG_SZ /d "C:\mon_image.bmp" /f :EOF
here is only for lock screen a code to save as powershell extension .ps1:
You just need to modify line 3 with the path of the file.
#Path of the images ex: "https://mysite.core.windows.net/w" $LockScreenSource = "C:\Users\tech\Downloads\330.png" ################################################################ if (-not [string]::IsNullOrWhiteSpace($LogPath)) { Start-Transcript -Path "$($LogPath)\$($env:COMPUTERNAME).log" | Out-Null } $ErrorActionPreference = "Stop" $RegKeyPath = "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\PersonalizationCSP" $LockScreenPath = "LockScreenImagePath" $LockScreenStatus = "LockScreenImageStatus" $LockScreenUrl = "LockScreenImageUrl" $StatusValue = "1" $LockScreenImageValue = "C:\Windows\System32\oobe\LockScreen.jpg" if (!$LockScreenSource -and !$BackgroundSource) { Write-Host "Lock screen and background must have a value." } else { if(!(Test-Path $RegKeyPath)) { Write-Host "Creating a registry path $($RegKeyPath)."
