Hi, here is one more (very convenient) alternative:

For step 1) Search the internet for "KNOPPIX on USB". You can create a bootable USB-Stick (very easy) and you can run your computer without any restrictions.

step 2) remains

But ...

KNOPPIX is a Linux System.
It does the same as Windows but everything looks/works slightly different. Surfing the internet should be no problem.

Both ways are about equally complex.
