Yesterday ago some buyer came to my friends store n want to buy some lappy. After he see n compare all manufactured n version, he choose Compaq 510. Since it had no OS at all, he want to install Windows 7 x86 for his lappy n ask my friend to install the OS for him. So my friend ask me to install the lappy, well I accept his request n do immediately. Since I allready know Compaq 510 allready had slics 2.1 but hidden, I update with HP slp marker n then install windows 7 x86 after I download the file from this thread http://forums.mydigitallife.net/thr...nks-English-Spanish-German-French-X86-amp-X64 I had finished the job, but then since it's quitely new machine n it's for sale too I've had a question : IS IT LEGAL WHAT I'VE DONE? Note : If it's not legal, I will restore to the original factory default n told the buyer to buy Windows 7 retail.
