Purposely Interrupting Windows 8 Reset

I have a Toshiba Satellite Radius laptop. I wanted to reset it to default factory settings so its back to how I bought it.

After turning on the laptop, I pressed the 0 key, and it took me to Windows 8 recovery screen. I clicked on reset, and I said to erase all files.

The resetting process is taking a long long time. Only 24% completed in 1.5hrs.

Can I purposely interrupt the resetting process by holding the "power" button to turn the laptop off?

I am unsure if this resetting is occurring through Windows 8's recovery/reset feature, or it is a Toshiba software on the participation...

Don't do that, you may brick windows and computer.

I wouldn't do it. I did erase files on an Acer and it pretty well took all day to complete. I just let it do its thing. This one was infected with something I wanted totally gone.

There are to options available - Keep this computer and remove everything..

Keep this computer = quick format, rewrite

Remove everything = zero's out and wipe's hard drive - takes a very long time.. It appears this is the option you choose..

i think reset was wrong choice ,should have be a recovery option i think ,a an option to pick use recovery partition
