This only works if you have a legitimate copy of windows ^_^

1. Go to the Download Windows 10 website. (LINK REMOVED)*

2. Under Create Windows 10 installation media, click Download tool now and Run.

3. Choose Upgrade this PC now, assuming this is the only PC you're upgrading. (If you're upgrading a different machine, choose Create installation media for another PC, and save the installation files.)

4. Follow the prompts.

5. When the upgrade is complete, go to Settings Update & Security > Activation, and you should see a digital license for Windows 10.

Due to the policy stated that "user's shall not advertise any Unauthorized Third Party Software in any form" you will need to go to the official Windows 10 Download Page, (can be found in the CNET article)

This has been a thing for years now ive done it to quite a few windows 7/8 keys in the past. Cool to see this is still a thing even tho it was suppose to end a while ago.
