I have a Windows Server 2022 Standard edition license key I obtained from Azure for Students (therefore from Microsoft directly), and it has worked perfectly fine for quite some time. I used it for a virtual machine, but I lost that VM when the disk used to store it died.
Now I'm trying to make a replacement VM and use that key for activation (I know the key only allows for non-commercial use, I'm still a student). But, every time I try to activate Windows, it tells me that "the activation server determined that the key is invalid".
What can I do? I never shared my key with other people (the document where I store it is password protected, and I'm the only one who knows such password), so I'm the only one who has ever used that key. I can't get it to work, and the Azure for Students Software portal won't give me another key (at least for now). Any ideas on how to solve this, or at least contact Microsoft for help?
Thanks in advance.
