During Repair of Dell XPS Laptop, I lost Windows 7's
Cover, which I got as Upgrade from Vista (so no
sticker on laptop). It includes Windows Serial No.
It lost this morning, and I installed Windows
without this key, but as need to activate within
30 days, I have to find some solution.
Two Software I found for this work (as I had already
installed Windows 7 on my old bad sector hard disk)
It has Free, Personal Use, working perfect
Free for Demo, not perfect and PAID:-)
Finally, I attach old harddisk, boot windows 7 (old installation),
install both software, Recover-keys find few things
Office, Call for Duty and 1 more, but now Windows key,
Then install Belarc Advisor and it create report and
show me in Web browser, yes it contains Windows keys
with IE serial key. So I got the key to Windows Activation.
It save money and something that Punjabi don't like to do...;-)
