If you find that you are unable to access the Games folder in Windows 7 or its link does not open or you cannot run a game from it, here are a few things you may want to try.
To open the Windows 7 Games folder, you’d normally click on the Games Explorer link in the Start Menu.
If you cannot see the Games link there, click Start > Right Click > Properties > Start Menu tab > Customize > Select Games > Display as a link or Display as a menu > OK > Apply > OK
You can also type Shell:Games in Windows start menu search bar and hit enter to open the Games folder.
But if the Games Explorer folder does not open in your Windows, then do this:

Type cmd in Windows 7 start menu search. When cmd appears as a result, right click on it and select Run as administrator.
In the elevated command prompt, type
regsvr32.exe gameux.dll
and hit Enter. This will re-register the gameux dll file.
Now if on running a game from the Games Explorer, you get an error message :
This file does not have a program associated with it for performing this action. Create an association in the set associations ControlPanel then, open regedit and navigate to following key:

HKEY_CLASSES_ROOT\lnkfile
If it doesnt exist, then in the RHS, create a new String value (REG_SZ) Call it IsShortcut . Click OK > Close Regedit > Reboot.
Trust it helps!
Go here if you find that your Games Explorer is slow to open in Windows 7.
