Windows 10 is the biggest piece of shit ever.
The amount of services and shit that just keep reactivating even though you disable them is absurd.
On start-up it takes about 10minutes to calm down from 100% CPU usage.
Now this isn't down to my laptop, as there is literally thousands of cases on the internet.
that sums it up doesnt it
and then "or I want to learn how to install Windows 7 on the laptop."
just install win7 or 8.1, and what do you mean by "learn how to intstall win7" ?
