I have done this process twice, once with my son' s laptop (Acer) and once with my own PC ( generic self build ASUS mboard). The laptop upgrade was a total disaster. On first reboot it failed to find a driver for broadcom modem and hAlted in dos. At this point you are screwed as you can only rollback when you get into the first Windows 10 screen i.e. when you decide you didn't like it after all. My son had done no backing up and didn't even have a restore disk to recover the original Acer version of Windows 7 from the hidden partition. The only way back was a complete format, create an Acer recovery disk and set back to factory default.
My own PC upgraded without a hitch. So its al down to the hardware and whether Windows 10 has appropriate drivers. If you have an off the self machine Google to see if there are known issues. Then backup everything you can onto external hard drive ( emails. pictures, videos, downloads, purchased software etc) and make sure you have a Windows 7/8) recovery disk you can boot from to get everything back in the event of disaster.
In years of upgrading from Windows 95-> Me -> XP -> Windows 2000 -> Windows 7 etc it is so common to get an issue with drivers that it is nearly always better to buy a new faster larger hard drive ( C drive) and install clean from scratch then set old drive to be D drive. That is my recommendation.
Best of luck.
