Note: Please make sure you understand the EULA before you perform this trick. Making any functional change in the operating system *might* be considered illegal by Microsoft.

Note: Editing the registry has the potential to cause serious (and unrecoverable) damage to your PC. If you are at all uncomfortable editing the registry, please do not attempt the following.
1. From the Start button, type REGEDIT into the Search box, then press Enter to launch the Registry Editor (regedit.exe).
2. Locate the following key in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM
3. Modify the following value (REG_DWORD):
Composition
Change the existing value to 1.
4. Modify the following value (REG_DWORD):
CompositionPolicy
Change the existing value to 2.
5. Close Registry Editor.
6. Open an elevated Command Prompt window. To open an elevated Command Prompt, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator. You can also type CMD in the search box of the Start menu, and when you see the Command Prompt icon click on it to select it, hold CTRL+SHIFT and press ENTER.
7. In the Command Prompt window, type
net stop uxsms
press Enter.
Wait for the Desktop Window Manager Session Manager service to stop, then type in
net start uxsms
press Enter.
Wait for the Desktop Window Manager Session Manager service to start.
8. You *might* need to restart your computer.
