Reset This PC is a recovery feature available in Windows 11 and Windows 10 that lets you reinstall Windows from scratch with just a few taps or clicks—just like a factory reset or restoration—but no installation disc or flash drive is required. You even have the option to keep or delete your personal files in the process!

For more information about this "last resort solution" and when it's a good idea to use it, see Reset this PC: What it is and how to use it.

The easiest way to start the Reset this PC process is through the Advanced Boot Options menu, as shown in the screenshot above.

The great thing about the ASO menu is that you can open it in at least six ways. That’s very handy, because the tools you’ll find there, such as Reset this PC, can help you fix problems that are keeping you from using Windows normally.
