Aero is not working and windows startup with error " windows cannot connect to the sens server"

Original title: Aero issues and error message
Hi, i have windows 7 and its been running fine for over a year.
Recently Aero will not work and a "windows cannot connect to the sens server" message apears when it boots.
i created a guest account so i have been starting this account on boot up which has
aero disables and the error message.
Then i switch user accounts to mine and windows runs fine.
So whichever account boots first has the problems.

Hi,
Method 1:
Once you face this issue you can check in the Task Manager if there is a program running attached to it.

a.
Right click on Task bar and click on Task Manager.
b.
In the Windows Task Manager Window go to "Processes" and check if there is any program associated with those folders.

Method 2: 
You can also run the Microsoft Security scanner and check if any infections are causing the issue.

Note.
If any infections are detected then there is a chance that the infected data may be deleted.
Method 3:
Try performing SFC scan on the computer.
 
a.    Click “Start”, click All “Programs”, click “Accessories”, right-click “Command Prompt”, and then click “Run as administrator”.
If you are prompted for  an administrator password or for a confirmation, type the password,
or click  “Allow”
b.    Type the following command, and then press ENTER:  “sfc /scannow” (without the quotes)  

 [The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.]

Method 4:
If you are unable to resolve the issue, then I suggest you to check in a clean boot state and try renaming the folder.
Clean boot helps you determine if any third party application may be the cause of the issue.
If you are able to determine, if any third party application is causing the issue then you can uninstall the application.

Note: Do not forget to return the computer to normal after completing the troubleshooting by following the steps under step 7.

• Download the Microsoft Windows ISO (installation device) from the following website:
  
• http://www.microsoft.com/en-us/software-download/windows10
• Users must select the appropriate ISO, either 32 bit or 64 bit, depending upon their individual computer.
• Extract the ISO file to a separate USB device or burn the program to a compact disc.
• Run the Microsoft Windows 10 upgrade directly from the software that you have thus created.
