There are possibilities that are might be because of virus, so just run a complete scan and then see if you are finding out any?? Just try out the same and then post back the result that you get.

Even I thought of the same and I have already used the following antivirus by now but then they have not helped:

• Spybot search and destroy
• Malwarebytes anti malware
• Avg 2012
• Eset

They were able to find something’s like cookies and all and nothing else, the issue is still there, is there any other solution that I can try out, any further help for the same will be appreciated.

As far as I am aware it is concerned to Desktop Windows Manager Service and if you are not getting The same aero style that you were getting before then

• Try out the below solution and see if it is helping:
• First go in to start and after that click on run and then type “services.msc” without the quotes and then hit enter.
• After that find out the Desktop Windows Manage and then restart the service.
• If that does not work then try out the below command in the command prompt and see if it is helping.
  sfc /scannow

I have tried out doing the same and it ended up with this:

What should I do now??

I think that you should reboot the machine here as sometimes after the DWM crashes it is a bit difficult to start it again but then it is not necessary. I just wanted to know that were you messing up with the modified Windows themes and all previously?? If yes then better switch back to the default Windows Aero theme and in order to do so just click on the aero.theme
File which will be in C:\Windows\Resources\Themes\aero.theme
Try out the same and then let me know if it is helping.

I just want you to open the command prompt as admin and in order to do that type cmd in the search and then run it as administrator and then enter the below command and then post the result that you are getting:
sc queryex sens> 0 & notepad 0
Just post it here so that I can have a better idea of the issue that you are facing.
