If a laptop comes with Windows 10 Home product key embedded in the UEFI BIOS, that means if one doesn't use the ei.cfg file, it would install Windows 10 Home by default now the question is, if that uses opts for an upgrade to Windows 10 Pro from within Windows, does that same key get upgraded or will Microsoft send a new key for Pro?
MSDM Table keys are fix and won't be changed by MS in any way. To upgrade you'll need an Pro key as usual.
You can simply upgrade to Pro by entering the generic Pro key (ending on 3V66T) at "change product key", but you have to establish a HWID for Pro first (to activate the upgrade by HWID) or use a KMS solution to activate it.
Hmm, to my knowledge it's not only the key in the MSDM table but also the specific machines hardware ID connected to that key at MS Servers. Can remember Yen posting about the new OA3.0 activation process when it appeared back in the days. If i remember correctly the process includes any key being registered at MS activation servers. No registration = no activation.
I have a Windows 10 PRO OEM system builders edition key that I was wondering if I can inject it into the BIOS to have it automatically picked up during installation even if I didn't use the eif.cg file not a big deal really but it would be nice to do this
As LatinMcG posted it is possible to integrate the key. Technically Win 8.1 and Win 10 OA3.0 are the same. I only tested with a VMware ROM file and it worked nicely, tricky part was to get a valid table. Question still remains whether the key will activate afterwards.
can you post a step by step instruction guide on how to integrate the key? It will activate as it's not some generic key from MSI but I bought it on my own
That would be LatinMcGs field, i'm a noob with this. No clue about the differences between VMware BIOS and an 'real' one. I did it with the help of a thread by Yen in the Virtualization sub-forums about adding own keys into a MSDM table.
flashing rom to insert a key is overkill. just use the oem method i guess as its safer than flashing a bios i do it with a spi programmer and make backup.bin then use hxd hexeditor to Ctrl F (search in hexmode) 01 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 then right bellow it is Key.. change it with same CAPS then file save as "newkeybios.bin and flash to chip.. to insert MSDM key i believe u need to use EFI Tool or phoenixmodtool (efi is always phoenixmod tool.. like ami and such) but if its there.. just change it with hexeditor
Thanks a lot. that's a bit too complicated for my knowledge. I'll just stick to the eif.cg then and install Pro that way
