my pc is dell optiplex 745 bios modded slic 2.3 my os windows 7 sp1 ultimate up-to-date i had installed my os several times using oem slp key and last time i did that using another oem slp key"non-brand" my os had activated oflline with no problems but when checked the key i had writed in PID file i found another key previosuly activated from first time i installed and activated windows 7 i discovered that all os installation times i did was the same first oem slp key my questions: did that means the first oem slp key live in my bios and every time i do a clean installation of windows 7 it will be auto activating using it.....of course with the same cert? that lead me to think that matter is similar to windows 8 activated with oem dm key in pre-activated windows 8 pc...althougt there are important deffernts between both? if i want change my first oem slp key-as i did in PID file-to another one how can i do that? no relation between what i have aiming to with windows 10 at all best regards
1. How did you inserted the key (& the cert) previously - manually by hand/using autounattend.xml/using some scripts? 2. Using slmgr.vbs: Code: slmgr.vbs /ipk NEW_KEY
2. Using slmgr.vbs: wow worked like a charm many thanks but still wounder if a new os install needed does the new key will be embedded in my bios?
