    Can anybody help me on this subject?

    I recently format my computer and I do not have such problem before format.

    After the format everything works fine but Aero.

    My score are good enough to work Aero and I try so many things from so many forums but none of them work.

    I try gpedit options, I try some other alternative solutions but none of them worked.

    My main problem is I cannot see any thumbnail in the task bar and for this purpose I learn that Aero should work properly.

    Here are some snapshots from my computer and I can provide more to solve this issue.

    Thanks for your help.

    UseMachineCheck, and set its value to 0.

    Blur, and set its value to 0.

    Animations, and set its value to 0.

     

    4) Close Regedit

     

    5) Click on Start and type CMD with administrative Priviliges

     

    6) Now type following command
