Will my data lose if i upgrade windows 10 64bit from 8.1 64 bit?

Solution
When you upgrade, you should be prompted with an option to 'Keep my files, programs and settings', select this and it won't. That said, i'd have to advise backing up your data anyway just in case you run into any issues with installation. Hope this helps! :)
