Windows 10: Spontaneous Theme Change

Over the last few months, Windows 10 has been creating a new unsaved theme and making it current, overriding my preferred theme. I can switch back to my preferred theme and delete the spontaneously-created one, but it's really annoying as it sometimes happens several times per day, sometimes even two or three times within an hour.



Any ideas on how I stop this?



I'm running the latest updated version of Windows 10 on a one-year-old MSI GT72 laptop with one external monitor... Nvidia GTX 970M... if any of that has any bearing on this problem.

I've had that with themes I've created, I just save the newly created theme (as it's exactly the same as my theme) & delete the original & usually that fixes it.

In my case, it doesn't. As stated in my original message, it keeps coming back. I delete it, switch to the theme I've created, and a while later (anywhere from a few minutes to a few days) another new unsaved theme is created and win10 switches to it. So, I go through it all again... and again... and again.

Yes, I wasn't sure whether you'd saved the theme before deleting the original.

I forgot to mention in my original post...

My preferred theme is different from the one spontaneously created by Windows 10, so just saving the new one and carrying on isn't something I want to do.

An update:

A few days ago, I realized my desktop wallpaper was far too big, area wise. I'll explain...

Originally, I had a three-display set-up, two external monitors and the laptop's screen. So, I was using a single wallpaper wide enough to cover all three. Now, there was an inherent problem with this right away because my external monitors were both 1920x1200 whereas the laptop screen is only 1920x1080. There was already some wallpaper "hanging off" the edge of the laptop screen.

Then one of my monitors died and I haven't replaced it. That meant my desktop wallpaper was now a full 1920 pixels too wide as well as being too tall for the laptop screen. So, I resized it, got rid of the extra width.

It took a couple of days for the mysterious theme-switch problem to happen again with the resized wallpaper, but oddly enough, there seems to be another wrinkle in all this. The problem cropped up again just before (or just after, or while) I was installing a demo version of CorelDraw X8 (not that I suspect it has anything to do directly with Corel's product, but it did bring back a vague memory of it happening around the time I was installing/uninstalling other software).

So, now I've removed the wallpaper altogether to see if that has any effect.

Okay, it's got nothing to do with wallpaper. The same thing happened yesterday with no wallpaper.



And it was right around the time I installed CrazyBump. So, I'm thinking now it has something to do with installers.
