So you did the the antimatter of what you asked. If it was to reset ad loose everything what was the point of your question?
I am also in a similar dilemma. Here is where I am stuck. I am on the laptop which came with Windows 10 Home SL version. I want to make it into Windows Pro. I can reset the Laptop to Factory reset. oem-dm key I checked as of now show license to Windows 10 Home SL version. My question is if I create a DVD with $oem$ folder with pro ei.cfg and install over the same machine using files from Multi OEM project, I get new Pro version in my oem-dm key? Will I be able to activate the Pro version? Can anyone help me to solve this puzzle?
No. 1. the oemm can't be changed like slic could on 7. 2. the ei.cfg is only for doing a clean install of Pro/Ent/Edu with a oemm bioskey for core/home. 3. and the ei.cfg doesn't need to be in the oem folder, just the \sources folder. 4. the Multi_OEM project is not for changing oemm but it "uses" the oem:em key. Search for one of T-S's VHD posts, changing the hdd would be to intrusive on a laptop.
Thanks for the reply, that clears the doubt. Now How shall I go about to alter the HWID to Pro? Any links will be helpful as I have 2 HDD. M2 SSD + 1 TB HDD on that laptop. So Removing the HDD will give me a new HWID?
Can we make the Windows 10 forget looking (or bypass) for oemm keys for activation so that I can activate through upgrade via Windows 8.1 and get new digital entitlement? Laptop which came with OEM home version needs to make PRO. I don't mind losing the OEM status. It ignores GenuineTicket.xml and goes to check oemm instead.
I'm forgetting the fact, to upgrade on a system with an oemm bioskey for home and you want to go from 8.1 pro/kms to 10 pro, you have to use a 10240 iso, that one can't readout the oemm bioskey
Thanks I did succeed by going via Win7 + daz + 1511 upgrade. Now Windows 10 Pro is activated. Thanks for guidance
