[SOLVED] Activation lost when upgrading to Windows 11

[ThunderOne]

Hi, I was using Windows 10 Home activated with an OEM license, I no longer have the product key but it was automatically activated everytime I did a new install.

I did a fresh new install for Windows 11 Home and it didn't activate automatically so I went back to Windows 10 Home in order to keep my activated product and upgrade through system update to Windows 11 Home when it is available for everyone but now my Windows 10 Home didn't automatically activate either and I don't have the product key so I completely lost my activation. 😓

Anyone know what can I do?

Not really much you can do if you forgot the product key and the activation is lost. You can contact Microsoft.

Only people who can fix activation problems like that are MIcrosoft. they should have details of PC and or email address on their servers. Its not up to the user to remember the info anymore, most licence keys stored on win 10 PC are dumbie keys, the real ones are on MS servers.
