Recently I tweeted a picture of the custom Windows 10-style splash screen I’m using in an implementation of Windows as a Service with SCCM (aka in-place upgrade), and a couple of people asked for the code, so here it is!
A while ago a blogged about a custom splash screen I created to use during the Windows 10 upgrade process. Since then, I’ve seen some modifications of it out there, including that of Gary Blok, where he added the Windows Setup percent complete which I quite liked. So I made a few changes to the original code as follows:
- Added a progress bar and percentage for the Windows Setup percent complete
- Added a timer so the user knows how long the upgrade has been running
- Prevent the monitors from going to sleep while the splash screen is displayed
- Added a simple way to close the splash screen in a failure scenario by setting a task sequence variable
- Re-wrote the WPF part into XAML code
Another change is that I call the script with ServiceUI.exe from the MDT toolkit instead of via the Invoke-PSScriptasUser.ps1 as this version needs to read task sequence variables so must run in the same context as the task sequence.
I haven’t added things like looping the text, or adding TS step names as I prefer not to do that, but check out Gary’s blog if you want to know how.
To use this version, download the files from my Github repo. Make sure you download the v2 edition. Grab the ServiceUI.exe from an MDT installation and add it at top-level (use the x64 version of ServiceUI.exe if you are deploying 64-bit OS). Package these files in a package in SCCM – no program needed.
To call the splash screen, add a Run Command Line step to your upgrade task sequence and call the main script via Service UI, referencing the package:
ServiceUI.exe -process:Explorer.exe %SYSTEMROOT%\System32\WindowsPowershell\v1.0\powershell.exe -NoProfile -WindowStyle Hidden -ExecutionPolicy Bypass -File "Show-OSUpgradeBackground.ps1"
To close the screen in a failure scenario, I add 3 steps as follows:
The first step kills the splash screen simply by setting the task sequence variable QuitSplashing to True. The splash screen code will check for this variable and initiate closure of the window when set to True.
The second step just runs a PowerShell script to wait 5 seconds for the splash screen to close
The last step restores the taskbar to the screen
For that step, run the following PowerShell code:

Hi, I have been unable to get this to run without crashing on Win 10 1903. The screen runs for about 7 seconds then crashes out. This happens regardless of running the scripts directly or if I run it from a task sequence.
This is fixed now: https://smsagent.blog/2020/03/12/windows-10-splash-screen-issue-fixed-for-w10-1909-configmgr-task-sequence/
Can this run after a reboot on the lock screen or does it still require to be run in User context (only when user in logged in) Thanks
Only when user is logged in
Hello
Such a nice script, but when upgrading from W10 1903 to 1909 the Splash Screen only shows up in 10 seconds then close againg?
This is now fixed: https://smsagent.blog/2020/03/12/windows-10-splash-screen-issue-fixed-for-w10-1909-configmgr-task-sequence/
does this still work with 1909 upgrade ? script seems to run for a few seconds then just closes. TS keeps running
Just fixed this today: https://smsagent.blog/2020/03/12/windows-10-splash-screen-issue-fixed-for-w10-1909-configmgr-task-sequence/
Hi
Im not quite sure what has happened, but now when I run this in my IPU TS, the TS progress window put itself over the Splashscreen. I can click the background and it will hide the progresswindow, However, each update will bring it to the front again.
Im sure when I tested this a month ago, this wasnt the case. Any idea what might be wrong here?
Same for me!
Did anyone figure out a fix for this? I still keep getting the TS Progress Box on top of the splash screen.
this is pretty cool, and i have developed my own front end similar to this one. i have been looking for some info on how to get the 2nd bar action info either from powershell or WMI to be able to display that info in a custom GUI. onevinn osbackground actually does this, but have not been able to find any info on how to accomplish this to use in my custom GUI. the sub action info is info that is provided and not assigned to a variable like the 1st line is. does anyone have any info or can point me in the right direction to be able to get that info?
any way for this to “regain focus” – On Windows 11 the start menu opens automatically after OOBE, and thus covers up the splash screen ( using part of your splash screen code for a similar project around autopilot)
