Hello Community,

I have a problem and need help:

My company bought 22 PCs with 22 Windows 11 Pro DSP OEI keys. My IT staff installed these keys on all PCs. Unfortunately, after one year, we lost the physical copies of these keys.

Everything was fine until one PC updated to the 22H2 version of Windows 11 Pro. After the update, this PC showed that the key is invalid, and Windows is now not activated.

I am worried that other PCs might face the same problem in the future. Has anyone had this issue after updating?How can I fix this and activate Windows again when I lost the physical keys?

Please help me.

    I had go back to previous backup before up date. Still don't know how to actually fix it though. But my windows is activated again. I will not install system update again until I know it's been resolved
