You cannot backup your own files however the slp cert is identical for every single Dell system running factory settings with Windows 7 Home Premium or installed with a Dell Windows 7 Home Premium Reinstallation DVD. If you get a Reinstallation DVD from Dell you will use the same activation mechanism. I have backup up the cert for each Dell version of Vista and 7 so all you need to do is copy them to the extracted folder of the ABR program and run the activation restore.
my daughter's N5010 has a failed hard drive that i want to replace and load win 7 home premium (that was what was on it when she bought it new in 2010)i have downloaded an .iso from digital river and will burn to dvd for install.  however, the COA on bottom is quite warn and i can't read the product key, in addition, the bar code is also quite warn and may not scan.  the hard drive i took out is dead so there's no getting the key from it.  i have read several postings here and watched some videos that come up on google searches, but don't know if i'm getting good information.  how might i get the correct key to activate the os?  is doing this on a new hard drive different from the descriptions about reinstalling on the original hd?  i called dell support and was told by a guy difficult to understand that the downloaded .ios will not work with this laptop, but i suspect he wanted to sell me a software warranty and new discs.  perhaps he is correct?  what is my best option here?thanks for your consideration... ...<><
