Special notes for Windows 10 Enterprise
windows 10 enterprise edition have two final releases. The 90 day evaluation release and Official final release. If you got the 90 day evaluation copy installed, we’re sorry that there is no way to activate it. Download Windows 10 Enterprise Official final release here : . And Follow the above steps and you are good to use a lifetime activated Windows 10 Enterprise OS :)
Why My Windows 10 copy says expiring after 180 days even after cracking ?
That’s how KMS Activation works. KMS gives activation upto 180 days. Once you reach 179 days, KMS tool will automatically re-apply a new key to extend for more 179 days (180 of total). So what you got is a lifetime activation ! If you used a portable activator you will have to run in 180 days most of the time. If you used KMSPico it will do the process itself
