"Factory Reset Wipes Everything": What Actually Survives Reset This PC

What the reset actually does

"Reset this PC" — Settings > System > Recovery on Windows 11 — offers two modes and hides the important part on a second screen. "Keep my files" reinstalls Windows and removes applications, but your user profile survives intact: browser logins, app settings and every cache folder under %USERPROFILE% ride along to the new install. "Remove everything" wipes the Windows volume properly, and "Cloud download" versus "Local reinstall" changes only where the fresh image comes from — one fetches roughly 4 GB from Microsoft, the other reuses files already on disk. Neither mode, with default settings, is a data-destruction tool.

The toggles that matter live behind "Change settings" on that second screen, and both default to the fast, less thorough option. "Clean data" turns the reset from a quick format into a genuine wipe pass, at the cost of hours instead of minutes. "Delete files from all drives" extends the wipe beyond C:, which counts on any machine with a second partition or drive. The dialog is honest about the wording; the problem is that the fast path is the one people click through without reading.

What survives the default reset

Nothing on this list is exotic corner-case territory — it is the default behavior of the default flow. Someone who clicks through "Remove everything" with default settings and hands the laptop to a stranger has a real chance of handing over data with it. The good news: every gap has a toggle, and all of them are visible in the dialog if you know where to look. The bad news: the names promise hygiene, not security, and reading stops exactly where it starts to matter.

• Every drive except C: — a default reset touches the Windows volume only; data on D: and E: sits there untouched
• Your user profile after "Keep my files": browser logins, app caches and %APPDATA% leftovers travel to the fresh install
• Non-Windows partitions — an ext4 partition from a dual-boot Linux setup is ignored, not deleted
• Recoverable file content — without "Clean data" the drive is only quick-formatted, and on an HDD the old data is one recovery tool away
• The recovery partition, WinRE, UEFI settings and TPM keys — reset never touches the firmware layer
• Your device's link to your Microsoft account — the activation digital license and find-my-device records live server-side, off the disk

The handover sequence that actually wipes

For a machine leaving your hands, the order is: sign out of everything first — Microsoft account, OneDrive, browser sync, any licensed software — then Reset this PC > "Remove everything" > enable "Clean data", and enable "Delete files from all drives" if other volumes ever held data. On an SSD, TRIM plus the wipe pass puts recovery out of reach of anyone short of a forensics lab; on an HDD, that pass is the entire difference between a wiped disk and a quick format. For genuinely sensitive drives the gold standard is BitLocker before the reset or a dedicated wiping tool, and the finishing touch is removing the device from your Microsoft account's device list so the new owner inherits nothing.

For a machine you are keeping, the logic flips: "Keep my files" is a legitimate fresh start for the OS layer, and the surviving profile is a feature, not a bug — it is what keeps your browser logins and application settings alive. Just do not confuse the two scenarios, because the reset honestly serves both and the myth serves neither. Wiping for handover, fresh system for yourself; the dialog supports both once you stop trusting the defaults.
