Refresh windows without a new install.

[Compact5]

Hello,

Is there a way I can re-install my windows 10 just from the PC, without the need for a new key or CD insertion etc.

My just has so much junk on and I just want it to be how it was from new, but I don't want all the hassle of having to get a new key etc.

Thanks.

If its activated now you dont need a key. You can reinstall and it'll activate after

If you dont want to use a dvd you can get the mediacreation tool get the ISO and use rufus instead.

And you can put the install on a flash drive

Don't need a new license.
You just need a USB stick. 8GB or so.

Create your own USB here:
