Question Changing background of UEFI boot/shutdown screen

[onespeedbiker]

While one can easily change the Windows 10 login screen, I can't find any way to change the background of boot/shutdown screen; the screen with the twirling circle. This can be done easily with Windows 7 with a program called Windows 7 Boot Updater, but I can't find anything for Windows 10

well, this looked interesting until i saw its for windows phone - https://docs.microsoft.com/en-us/windows-hardware/customize/mobile/mcsf/custom-shutdown-screen

most of the answers talk about changing the colour, which isn't the right answer. Or wrap around to the login screen changer.

@gardenman might have some ideas.

this isn't the 1st time I have looked into this - https://forums.tomshardware.com/threads/disable-login-and-shutdown-screens.3390595/

Good chance you can't do it easily or all big oem would have custom shutdown screens.

Edit: Please read this entire post, and the entire pages of the link before even thinking about it. I just worry that if you try it, things could go wrong.

I have not tried this, so do so at your own risk:

HackBGRT: Windows 10 UEFI Boot Logo Changer

Windows 10 allows you to change the login screen (sign-in screen) and lock screen background image to a custom picture. However, before this, there was no

Such tools have been known to bring down a Windows install.

Quote from that page:

It’s important to note that HackBGRT must be run computers that support UEFI (check if your PC supports UEFI) and use it only if you are booting with UEFI enabled. The developer of the tool also recommends disabling the Secure Boot.

Another quote:

Your Windows 10 PC might become unbootable if anything goes wrong while changing the boot logo.

Thanks all, I've decided to leave it alone until someone comes up with a better method.

Good idea (in my opinion). I think these programs edit/modify executables or DLLs where the pictures are stored. That's fine if Windows never updates or changes things. But Windows does update and change.

If you still want to try it, do it safely.

• Make a full system backup (with good trusted backup software)
• Run the program and test your system for a few days.
• Be prepared if things go wrong to restore the backup

... and keep in mind that Windows Update may restore the image back to default. Or running SFC may restore the image back to default.

I decided to get the paid version of Hasleo WinToUSB, so I now have several bootable USBs that run Windows 10, so I can experiment with such things and if it goes wrong I just wipe the USB and load Windows 10 again. But as you said,

... and keep in mind that Windows Update may restore the image back to default. Or running SFC may restore the image back to default.

So what's the point..

That's an educated guess that it will reset after an update. Maybe only after major version updates (such as 1903, 1909, etc). Such updates usually replace the basic files that run Windows (which is where things like startup backgrounds would be).

Anyway, if it works in your tests, then maybe it's worth using. Just don't forget that backup 1st, even if it works without issues on the test systems.
