My Windows is in Test Signing mode and I want to keep it that way as I'm a developer.

However, is there a way that I can get rid of the

Test Mode
Windows 7
Build 7600

in the bottom right corner of the wallpaper on my desktop?

This in not a duplicate of How to remove the test mode watermark on wallpaper? as they disable it there.

Is there a way to automate this so that it remains or is applied again after updates that roll back the edits?

You could run a program downloaded off the internet... Google "remove watermark test mode".

This post says that deleting these registry keys (or more likely renaming them) will work:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\CA\Certificates\FEE449EE0E3965A5246F000E87FDE2A065FD89D4]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\ROOT\Certificates\2BD63D28D7BCD0E251195AEB519243C13142EBC3]

You can also edit user32.dll.mui with a resource editor or even a simple hex editor to replace the strings with null values or spaces.

Thanks for your quick summary. Hmm, I'm wondering what other effects removing a root certificate would have. Perhaps I could set the program to run on each boot, or trigger it to run after updates. Maybe I should look into the ability to remove it from the live GUI (by obtaining the handle and removing the labels)... –  Tom Wijsman May 29 '11 at 16:36

@Tom: You could always just edit the user32.dll.mui... –  Hello71 May 29 '11 at 16:37
