I've recently uninstalled DisplayFusion Free, as they only reason I installed it was to have different desktop wallpapers on each monitor, but I have since found an alternative. However, I find that the logon background is somehow still being managed by DisplayFusion, as it's stock images are still being cycled through with each unlock/log-in. I do not want these images cycled through, and I want to change it using another method I've used for a few years.

(Personally, I believe a free version of an application should not change base functionality of a system and then force those changes onto the user, but rather should just keep the original base functionality.)

Hmm - my understanding of the free version was that it changed it, but locked it down to that change. My mistake then.

However, I don't have anything else that would change it away from what TweaksLogon changes it to. The only three other applications I installed (the first two of which I uninstalled nearly straight away) were Synergy, ShareMouse, and Mouse Without Borders - none of these have logon background changing utilities in them.

Hmm, I just realised that the images are built-in Win7 theme images...

My apologies for the trouble - I'd heard that the DisplayFusion service had persisted post-uninstall in a past version (albeit some time ago), so I wasn't ready to say "the program's uninstalled, so it's not the culprit".

Yeah, nothing related to DisplayFusion in any of those places - it must be something else doing it.

Cheers! I'll try that.

Got to say, I'm impressed by support who assist with likely-unrelated issues.

EDIT:
I'll be damned - it was Mouse Without Borders. Didn't expect Microsoft's app to do that unannounced.

Thanks for helping me tracking it down.

EDIT 2:
I had some inspiration to deny write access by SYSTEM to that folder, and it works to deny access to Mouse Without Borders (and probably other boot-time applications ) , but allow user-run applications like Tweaks Logon access.
