Windows 10: Reinstall W10 on same PC

Hello All,
Am unsure whether I can do this.
A while back I was given a laptop with W 8.1 Home installed.
I took advantage of the MS upgrade option and installed W10. All activated with a new legit key assigned by MS.
Strange as it must seem, sometime later I 'cleaned' the PC and installed Ubuntu !
I have now seen the light and want to again install W10 using MCT.
Will I be able to activate using the legit key that was assigned previously given that I am installing on the same PC ?
Thanks,

:)

 

PC Build Steps

Ok just because I like steps i am going to create some steps. Please give me the stamp of approval/disapproval

• Install system in case
  • Remember to connect SSD and optical to same SATA ports on motherboard
• Turn on PC
• setup HDD
• run blend test in prime95 for 30-60 min
  • run realtemp at the same time

• While in Prime95 test
  • if CPU goes above 70c in RealTemp, I have a leaky CPU
  • if my system locks up or blue screens, there is an instability in the system somewhere
  • if my system does not lock up or blue screen, my CPU is not damaged and I am in the clear!

What do you guys think??

 

Reinstalling PC with upgraded free W10

My PC is running slowly... and so on, so I decided to reinstall it (back to the factory version). Problem is that now I have Windows 10 that I installed for free (in the time it was released), and the PC was bought with W8.1., so if I reinstall my PC i will
be left with 8.1

Am I going to completely lose my W10s, or can I somehow install it for free again? I did not change anything on the PC, it is still the same PC, it was just bought with 8.1 and the 10s was installed on it legally for free in the limited time

Hope you understand me

If not, how can I install w10s once again?
