I attempted to upgrade my Windows 10 Pro machine to Windows 10 Enterprise as I believe it is included in our E3 subscription. I used the instructions here; specifically I applied the command cscript.exe c:\windows\system32\slmgr.vbs /ipk NPPR9-FWDCX-D2C8J-H872K-2YT43.
I am greeted with the following error:
My understanding is that I shouldn't need a KMS setup; the license is included with our E3 subscription and should authenticate since it is AzureAD joined. I went hunting for a location to enable/activate Windows 10 Enterprise but do not see that option.
After further looking at the instructions, I note that the script is useful only for instances with a KMS deployed. We only have AzureAD with the M365. My understanding is that after auth and joining the AzureAD, our PCs should automatically upgrade to the Enterprise edition. No such luck.
Some assistance, please? Thanks!
