  Thank you for answering.  Unfortunately, the new OS is already installed.  Unless, I misunderstood the instructions it is too late to create an ABR backup.   The files are identical for all Dell systems which run the same version of Windows 7 e.g. every Dell which came with Windows 7 Home Premium has the same SLP key. I have backed it up for all versions of Dell Windows Vista and 7 so theres no need to back up in advance. Just follow steps 1a and 2 here: [URL]  
I purchased a Dell Inspiron N7010 about 4 years ago. I have the Service Tag number and Dell express service code, and the receipt from Staples.  Dell  has information about my purchase in their system. What I do not have is the activation code because the label under the laptop has worn out.  The computer did not come with any software disks.  I created a repair disk, which no longer works.   I had software problems, so I formated my harddrive and reinstalled Windows 7  from Digital River, whose link I got from the microsoft website.  Knowing  my product activation code was unreadable, I copied the product ID from  the system page in control panel.  My computer works beautifully.  Unfortunately,the product ID I got from the System screen in the control panel, is not the number microsoft is looking for activation. Is there anything I can do?  Staples and microsoft said they cannot do anything.  Support at Dell wants $120 to reinstall Windows 7, which is more expensive than purchasing a new Windows 7 operating system.  I also feel Dell could give me a break because it was their label that worn out.   Will purchasing a Dell recovery disk solve my problem?  Any other ideas?
