Does factory reset remove everything from PC on Windows 11?

Yeah, the Diskpart clean all command is actually one of the most thorough built-in methods if you really want to wipe everything. Unlike a standard factory reset that just deletes the file table, clean all writes zeros to every single sector on the drive, so the answer to "does factory reset remove everything PC" is technically no for the basic version, but this command absolutely does make sure nothing comes back.

Step 1: Boot from a Windows Installation USB

Step 2: Open Diskpart

In the Command Prompt window, type:

text

diskpart

Press Enter.

Step 3: List All Drives

Type:

text

list disk

Press Enter.

You'll see a table showing all your drives with their sizes. Identify which one is your main drive (usually Disk 0). Double-check the size to make sure you've got the right one!

Step 4 : Clean All (The Permanent Wipe)

Now for the big moment – type:

text

clean all

Press Enter.

This command writes zeros to every single sector on the drive. Every single bit of data gets overwritten. No recovery software will ever bring your files back.

Step 5: Close and Reinstall Windows

Once it finishes (you'll see "DiskPart succeeded in cleaning the disk"), type:

text

exit

Press Enter, then close the Command Prompt. You can now proceed with installing a fresh copy of Windows from your USB drive.

So to directly answer your original concern about "does factory reset remove everything PC" – no, not fully, but clean all does make your drive look like a brand new blank slate with no trace of your old files, which is about as permanent as it gets without physically destroying the drive.
