Thanks for the vote,
this is a headache but i have hope thank you for your help.
I hope the headache part isn't that you don't understand my instructions.
When you click Start, then Run and paste or just type-in the part in red into the box and click Enter, the end-user license agreement will appear. Go to the last line, skipping all the words and paragraphs. The Last line is what you are looking for. It will match one of the lines I have listed. The version of Windows is right above the line you see in the list I made. For example:
If you see:
EULAID:XPSP2_RM.0_PRO_RTL_ENThis will mean you have
Windows XP SP 2 Professional Retail and an XP, SP2 Retail CD is what you would need.
It all depends of the last line in the End User License Agreement.
