Transfer existing Windows to a new computer

Question

Hello. It would be nice that Windows will have option to uninstall all existing drivers and have ready to transfer it to another computer. Like I will buy a new computer, prepare Windows by some button and simply plug disk to the new motherboard. It will be nice to have an option for loading new drivers from USB, or it will find new ones automatically for RAID if it will be possible migrate raided disks from one motherboard to anotrher.

So if you can do it you will help many users on the world :-)

Thx.

Marek
