Windows 10 upgrade with Windows 7 MAK Key

Hello,

I have Windows 7 Pro 64 bits acquired through MSDNAA partnership with my previous university.

Problem : after formating and doing multiple fresh installs on my PC, I get "error 0xc004c020" when trying to activate my Windows 7 Pro, which activated fine before (MAK activation count seems to be at 0). Note: I never changed any hardware in my PC, and
my Win7 key was only used on this PC.

Microsoft Support told me to try activating it by phone.

Let's consider phone activation will be successful.

What will happen to my Windows 7 "expired" MAK key (activation count at 0) if I successfully upgrade to Windows 10 after activating my Windows 7 by phone. Will my expired MAK key turn into a retail Windows 10 key, allowing me to do fresh install on this
same PC in the future, OR, will it stay a expired MAK key (for Windows 10), preventing me from doing fresh installs after upgrading ?

Please help,

Thank you

 

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

Windows 10 upgrade with Windows 7 MAK Key

Alright,

I may try with Windows Update in the next few days then.

But, if I stay on Windows 7, I would like to know something about MAK keys.

Now that my MAK Key is "expired" (activation count reached 0), why does Microsoft Support ask me to try activating by phone ?

Is there also a limit on the number of phone activations ? Or is it unlimited with an "expired" MAK key ?

This MAK key stuff is really a pain for end users like me. I got my Windows 7 key from the MSNDAA partnership when I was a student at university,and it got expired for too many activation on the same PC... This is not something we should deal with. I'm not
an IT professional, and I used the same key on the same PC maybe... 4 or 5 times after formating. And now, I'm stuck with "error 0xc004c020" with a "bricked" Windows 7 key
