Review:

You can download and install trial full versions of almost all Microsoft products from TechNet Evaluation Centre. I've just gotten both the latest Windows Technical Preview (Windows 10) and Windows Server Technical Preview (Windows Server 2015). If you are someone who wants to get hold of freebies or wants to get your hands on the latest Windows version, these is highly recommended. Or maybe for self/ work lab certification/ education usage purpose. It comes pretty useful.

Validity:

There's a trial period validity for each products. Ranging from 60 to 180 days. Whereas for the Technical Previews there is a fixed expiry period. For Windows Technical Preview it expires on 15th April 2015 (about 6 months free usage) and for Windows Server Technical Preview it expires on 15th February 2015 (about 4 months free usage).

Note:

This should be used for non commercial purpose only. You are not allowed to profit from using these free installers. Should you require this for long term usage, I would strongly recommend you purchase a valid license. Not all trial versions can be upgraded to complete full version too. You may need to reimage/ reformat PC for that.
