It was very sudden and without warning.
At the point of time of instance, i was surfing the Internet with Mozilla Firefox and playing an album of song in Windows Media Player 12.
Naturally, i attempted to restart to see if the problem would go away by itself. However just as Windows Media Player 12 terminated Windows Aero returned and my theme was back to normal.
I navigated to the logs in Control Panel and i found this 2 suspicious entries which is related to the incident:
"A request to disable the Desktop Window Manager was made by process (Windows System Assessment Tool)"
Source: Desktop Window Manager
Event ID: 9010
"The Desktop Window Manager was unable to start because composition was disabled by a running application"
Souce: Desktop Window Manager
Event ID: 9013
However, i am very sure i did not initiate Windows System Assessment Tool at all. My WinSAT score was also in need of being refreshed but i ignored that.
WMP 12 had already played 52 songs with average 2 hours done.
Is there any conflict or issues between the any programs(esp WMP12) i was using that caused the WinSAT to act by itself?
Found a solution.
In the start bar search type "Task Scheduler"
This will bring up the Task Scheduler App.
On the left click the Task Scheduler library
next click microsoft
Right click on winSAT and go into properties and delete the trigger.
now it wont trigger the Performance test..
