Well , i have downloaded the Windows 8 Developer Preview and started using it and looks cool .

When i installed the Windows 8 Developer Preview , i did not provide any license key as such to activate it .

But i was wondering and was desperate to know how long the Windows 8 Developer Preview Activation is valid and below are the steps that i followed to find until when the Windows 8 Developer Build is active .

How to find the Expiry Date of Windows 8 Developer Preview ?

1. Press the Windows Key + R to open the Run window .

2. Type Winver and click enter

3. This will show a Dialog Window that shows the details of the Windows 8 along with the Expiry Date of the Evaluation Copy as March 12 , 2012 .

I hope we get a Beta Build by that time
