My girl friend has a Windows 7 x64 Home Premium installation on a Easynote LJ61 I used Windows Loader 1.9.5 with Dell - Dell - Dell to activate Windows Now I myself, have a OEM Dell Windows 7 HOME PREMIUM installation disk. I wish to activate my serial key on her notebook. I tried slmgr which gave a error. I tried other things as well Will the only solution be that i install windows 7 from the oem disk and then register the serial? My Dell Studio 1558 is slic 2.0 as well i think I activated my serial key on a retail gigabyte motherboard as well using the disk.
