Mine was already upgraded to Windows 10 several months back. So far so good. No problem at all. Sometime it does reset by it self because the default Windows 10 setting will perform auto update and restart the laptop when it is not being used. Just need to disable that setting in Update and Security > Windows Update > Advanced Setting > Select Notify.

Another advice before performing the upgrade, make sure your important software is still being supported by the Windows 10. It was really bad for me when after the upgrade, turns out my Bitdefender Free is not supporting Windows 10. But there were no notification about it at all, or perhaps it did but it's gone when it automatically restart during the upgrade process. So my laptop was really naked without an antivirus for almost a month.
