Windows kommer inte med bloatware, msi har lagt till det efter. Så ja du kan använda din nyckel.
There's nothing hard about it.It just may seem so if you never did it before.
Every owner should have a copy of a Windows 7 Installation disk.
Using a USB stick is the fastest way to install it.
Download any Windows 7 ISO(choose language and bit)
Unpack the ISO onto USB stick using MS Tool
Remove ei.cfg from Sources Folder = Finished
Clean installing Windows 7 x64:
Insert USB installation Disk
Start computer and choose boot from the USB stick
Pick your keybord layout
Agree to EULA
Choose Basic,HP,Pro or Ultimate
Custom Clean Installation(not upgrade)
Disk Options(Format all partitions then delete all until 1 left)
Add Driver(install Intel RTS from 2nd USB stick)
Let Installation expand and install files
Remove USB sticks during 1st reboot
Finish installation
Install Intel Chipset Software
Install netFramework 4
Install MSI S-Bar Utility
Install drivers for Graphics,Sound,Wireless,Lan,USB 3.0
Install other needed driver and software for your model
If you do a restore from a backup you will probally be installing old outdated drivers and software.
It's best to have the latest drivers on a USB stick ready to be installed before you wipe your drive.
The bios remains untouched by a clean installation.
