Complete Windows Privacy Checklist: What to Do Before Selling Your PC

Selling or giving away a PC that still has your passwords, browsing history, personal files, and software licenses on it is a serious privacy risk. This checklist covers every category of personal data on a Windows PC — and exactly how to remove or back it up before handing the machine over to someone else.

Step 1: Export All Saved Browser Passwords

Your browsers contain saved passwords for every site you've ever logged into. These are not deleted by a standard factory reset unless you use the "Remove everything + Clean the drive" option. Back them up first, then wipe them.

To back up passwords from all browsers at once: download SterJo Browser Passwords (free), close all browsers, run it, and export the full list to a text file. Save this file to a USB drive or cloud storage — not on the PC you're selling.

To remove saved passwords from Chrome: go to chrome://settings/passwords → click the three-dot menu → Delete all passwords.

Firefox: Settings → Privacy & Security → Saved Logins → Remove All.

Edge: edge://settings/passwords → for each entry, click the three dots and delete.

Step 2: Back Up and Deactivate Software Licenses

Many paid applications (Adobe, Microsoft Office, antivirus software) use activation licenses tied to your account or a product key. If you don't deactivate before selling, the new owner gets an activated copy of your software — and you may not be able to activate it on a new machine.

Back up your Windows product key first: download SterJo Key Finder (free), run it, and note your Windows product key and any other detected software keys. Save these to a USB drive.

Deactivate common applications:

• Adobe Creative Cloud: Open the Creative Cloud desktop app → click your account avatar → Sign Out. This deactivates all Adobe apps on the machine.
• Microsoft Office (retail license): Open any Office app → File → Account → Sign Out. Also deactivate via your Microsoft account online under Devices.
• Antivirus software: Most antivirus apps have a deactivation or "unlink this device" option in their dashboard. Check your vendor's documentation.
• Other licensed software: Check each application's Help or License menu for a deactivate option before uninstalling.

Step 3: Export Saved WiFi Passwords

Windows stores the passwords for every WiFi network you've ever connected to. These won't transfer to your new PC automatically.

Before resetting, use SterJo Wireless Passwords (free) to view and export all saved WiFi network passwords to a text file. Save it to a USB drive. After the reset, these network credentials are gone from the sold PC — and you have a backup for your new machine.

Step 4: Clear Windows Credentials

Windows Credential Manager stores saved passwords for network shares, mapped drives, email accounts (Outlook), and remote desktop connections. These are separate from browser passwords.

Use SterJo Windows Credentials (free) to see exactly what's stored, export anything you need to keep, and then clear the credential store before selling:

• Open Windows Credential Manager: Start → search "Credential Manager" → open it
• Under "Windows Credentials," remove each entry manually
• Under "Web Credentials," remove any remaining browser entries

Step 5: Clear Browsing History, Cookies, and Cache

Even if you remove saved passwords, your browsing history, cookies, and cached sessions remain. Cookies can sometimes allow someone to access accounts you're still logged into (session hijacking). Clear all of this before handing over the machine.

Chrome: Ctrl+Shift+Delete → choose "All time" → check all categories (history, cookies, cached images, passwords, autofill) → Clear data.

Firefox: Ctrl+Shift+Delete → check everything → Clear now.

Edge: Ctrl+Shift+Delete → choose "All time" → check all → Clear now.

If you're doing a full factory reset with "Remove everything + Clean the drive," this step is handled by the reset — but it's good practice to do it anyway before the reset, especially if you discover you need to delay or cancel the reset.

Step 6: Sign Out of All Accounts

Sign out of every account linked to the PC — not just browsers:

• Microsoft account: Settings → Accounts → Your info → Sign in with a local account instead. This unlinks the Microsoft account from the machine. Do this before the factory reset so the reset completes without requiring your Microsoft password.
• OneDrive: Right-click the OneDrive icon in the taskbar → Settings → Account → Unlink this PC.
• Steam: Steam → top menu → Steam → Change Account → Logout. Steam deauthorizes the device automatically.
• Epic Games Launcher, Battle.net, EA App, etc.: Each has a sign-out option in their settings — check each one before uninstalling.
• Email clients: Remove accounts from Outlook, Thunderbird, or Windows Mail before resetting.
• Spotify, Netflix, YouTube: Log out from within the app and also from the web interface under account settings → "Sign out of all devices."

Step 7: Back Up and Remove Personal Files

Before resetting, copy everything you want to keep to an external drive or cloud storage:

• Documents, Downloads, Desktop, Pictures, Videos, Music folders
• Any custom configuration files or project work stored outside the standard user folders
• Email archives if using a local email client (Outlook .pst files, Thunderbird profile)
• Game saves (usually in Documents or AppData — check per game)
• The password and license key export files you created in Steps 1–3

Step 8: Factory Reset Windows Securely

A standard factory reset is not sufficient for a PC you're selling — a determined buyer could potentially recover files from a "Reset" that didn't include drive cleaning. Use the secure option:

1. Open Settings → System → Recovery (Windows 11) or Settings → Update & Security → Recovery (Windows 10)
2. Click Reset this PC → Remove everything
3. When asked how to reinstall Windows, choose either "Cloud download" (downloads a fresh copy) or "Local reinstall" (uses existing Windows files)
4. On the "Additional settings" screen, click "Change settings"
5. Enable "Clean the drive" — this overwrites all data on the drive so that files cannot be recovered. This step is critical for security before selling.
6. Click through and confirm — the process takes 1–3 hours depending on drive size
