"because Windows 8.1 is last OS that will not be able to penetrate personal
data as Windows 10 can(by license at least) ."
correct me if i am wrong but i think Micro$oft updated there privacy policy
for windows 8, 7 and 10 so they were all the same
remember reading this somewhere
micro$oft can spy on you with window$ 95 as they control the source code it
may be that only now they can do it legally though
if your concerned about giving away your private data i would not use window$
8 XD
out of interest why do you use win8?
"So far i had success to access OS but wifi wasnt visible and Setup was
extremely slow and always breaks."
i would guess this is due to a lack of free drivers
you may need to get a external wifi card for this laptop or replace the
internal one:
