I'm currently using Toshiba Satellite C55-A5128 Windows 8.1. My OS is getting slowed down so I decided to upgrade to Windows 10. However I'm having plan B, which is to roll back to Windows 8.1 in case if Windows 10 is not for me. I'm worrying that I might lose Toshiba support utilities once I got into Windows 10.
Currently there is a partition for recovery (around 8.33GB) and I'm guessing that Toshiba's.

My question is whether Windows Recovery and Toshiba Factory Recovery is on separate drives so that when I install Windows 10 it's not overriding Toshiba Recovery Partition so I can have a backup options of rolling back to Windows 8.1 Utilities.
