If you need it update as good as fresh one you have to bring “WINDOWS GENUINE DISK "Same version product I.D. I am searching since from last 2 months I was not get Please help me installed.

As from Windows Vista, all Windows DVDs come with all versions of the Windows type they "advertise" (eg a Windows 7 Home Edition disk also has Windows 7 Professional). It is the product ky that you put in that determines which version of windows you get. The product key should be on a sticker on the PC somewhere.
There are some exceptions to this ... Windows Starter Pack (for tablets) and Windows Enterprise are not included in this way. Also, I believe that the same service pack version needs to be installed - eg a product key for a DVD with Windows 7 Home Edition AND Service Pack 1 will not work for a DVD for Windows 7 Home Edition WITHOUT ANY service packs.
So really you need to look for a Genuine DVD with the version of windows ans service pack on the Product Key sticker on the side of your machine.
