Key notes

The Microsoft InsiderProgramhas been available for quite some time and a lot of people are interested in it. It is a great way to determine what users would like to see in the final version ofWindows 10. But even the Technical Preview of the new system has issues, and one of them is not working CD key.Some participants ofWindows Insider Programshave reported that after they downloadedWindows 10Technical Preview, the system requires a CD key. After they type the key, an error occurs. The cause of this issue is a bug that is present in some copies ofWindows 10Enterprise Technical Preview.

Now you should be able to install your copy ofWindows 10Technical Preview without any problems and participate in Microsoft’s Insider Program in order to help Microsoft to create as good a system as possible. But remember, you should use Windows 10 Technical Preview just for testing purposes, and not as your everyday system because Microsoftis following every your step, and risking your privacy is probably something you wouldn’t like to do.

If the problem persists, here are some additional methods that you can use.

Solution 2: Disable VPN software

We noticed that manyWindows 10key issues occur on computers runningVPN software. In many cases, simply disabling the VPN tool fixed the problem. So, if you rely on a VPN to keep your online activity anonymous, temporarily turn off the tool and check if the problem persists.

Solution 3: Reset your license

Another quick solution to fixWindows 10key issues is to reset the license status.

Restart your PC and test if the key issue is still there.

Just as a reminder, Microsoft further improved Cortana and many other Windows components in the latestWindows 10Technical Preview. The new build also features different interface than the previous build, which convinced us once more thatWindows 10is not just Windows 8.2, but if you want to know the full story about this discussion, you should read our “Debate: Should Windows 10 be Called Windows 8.2?” article.
