I bought my Dell XPS a couple of years ago, and it came with a preinstalled version of Windows 7 64-bit. I would now like to format and perform a fresh install of the same Windows version.
I already have a Windows 7 64-bit installation disk (tested on an old server machine, and it works), I've written down the Product ID (found in Computer->Properties->Windows activation), which looks like xxxxx-OEM-xxxxxxx-xxxxx, and also, using a few different 3rd party programs Magic Jelly Bean, ProduKey, Belarc), I've found my Product Key, which looks like xxxxx-xxxxx-xxxxx-xxxxx-xxxxx.
Will these two be sufficient to activate my Windows after I format my computer? Do I need to first deactivate it somewhere before formatting to free up the licence?
