Windows 7 - Cant change Theme

Hello all,

I have a problem with my Windows 7 Pro 64 bit.
I cant change any theme settings, nothing, here look:



Sorry for the language its Dutch but it says:

"Your administrator has disabled one or more functions on this page."

I was like wtf, I am the Administrator

Does anyone know how I can solve this ?
I dont have any virusses or other nasty stuff according to Eset Smart Security, Malwarebytes Anti Malware and Kasperski online scanner (yes all the latest updates/definitions)

Only thing I can still do is Right Click on image files and set them as background and thats it.

I don't know if it matters but I am the only account on my PC and yes I am the administrator.

Sorry if this doesn't belong in this forum

Hi Dylantog,

Were you able to change themse before, or has this problem always occurred for you on this PC?

Thanks for your quick reply, well I always could change the theme and I did every now and then, and I just wanted to do that again and it gave me this problem...

Mmm...OK. Can you recall any changes you may have made to your system, between the time you could make the changes to themes, and now?

You can also try the excellent tutorial to fix the issue Theme - Allow or Prevent Changing

Thanks for your reply, I was able to fix it with the Local Group Policy.
The option was not configured but I Disabled it and now it works
I still got a question though, what caused it to disable themes...

ps, I cant change the system back to earlier because I disabled System Restore.

Hi. Glad I was able to help you.

I'm not sure what may have disabled it...did you perhaps play with the Aero themes and select Basic by any chance? Lets see if others can answer that.

At least, its working now

Nope, as you can see on that screenshot Aero was working
I just wasnt able to change anything.
