"Specs: Windows 21.02.2011"
Where did you get that from ?
It's useless information.
I'm assuming your operating system is XP since you started this subject in the XP forum..
How did that happen ? They're usually installed by default.
You may not need the Windows CD.
Go to Control Panel - Classic view - Add or Remove Programs.
On the left side choose Add/Remove Windows Components,
then Accessories and Utilities.
If Games has no check mark in the small blank box before it, try clicking on it to insert a check mark in it, click on OK at the bottom of the Accessories and Utilities window, then click on Next at the bottom of the Windows Components Wizard window,
- or do the same things if Games already has the check mark in the small box before it.
