Help! OEM Activation on top of installed TRIAL Win 7 Ultimae on SLIC 2.1 machine? So this is the scenario. A friend of mine has Dell M1330. There was a hard drive sector corruption and the hardware shop that worked on it - Backed up the data, - Installed a new hard drive - Installed TRIAL Window 7 Ultimate (as per the Hardware shop guy.. not confident about him) - Installed Office etc - Migrated her DATA to the new HDD .. C & D Drives Now this trial would expire in 30 days. I was thinking of doing the following: - Updating the BIOS to SLIC 2.1 (Available on forums) THEN - Use the OPAtool etc to change the Certificates & Keys and ACTIVATE the machine. - Is there some way to make the existing Win 7 become OEM? I am wondering if this would work on the TRIAL or not? It doesn't say trial version or anything? Not sure if he installed a retail or other version? If yes, great. If not, what is the EASIEST way around without Re-Installing everything. CAN I THEN.. Maybe install OEM version on top of existing Win 7 and activate it using OPATool. Then get the Hardware shop to do the stuff again. Thoughts, ideas to minimize effort & time.
