Hi Jack, rest assured, activating Windows 10 will have absolutely no effect on your data, it will remain intact, you have nothing to worry about . . .
Will I lose my files upon activating Windows 10?

Hey, I am currently running the Windows 10 trial edition (with the watermark in the bottom-right hand corner) and am going to activate Windows 10 once I receive my product key. My question is will I lose all of my files I downloaded when activating Windows 10. While it may seem obvious and a silly worry, I just want to be sure since I have over 150GB of games already installed and I would hate to download them all again.

There is no trial version, except for Enterprise which is a business version and can only be activated by large organizations using Volume Licensing.
Go to Settings > Update & Security > Activation and report back what it lists at the top under Status and Edition.
If it's retail Windows then you can buy a Product Key to insert it. I would buy only from a major retailer who backs their sales. Any discounted key is likely not genuine. Safest is to buy from Microsoft here: http://www.microsoftstore.com/store/msusa/en_US...
You won't lose anything by activating, unless you have a business version which must be reinstalled to activate as a consumer. Then back up and reinstall a consumer version.
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
