A factory reset returns Windows to a clean state — removing accumulated junk, fixing persistent errors, and making a slow PC feel new again. This guide covers all three methods: reset while keeping your files, full wipe, and clean install via USB. Works for both Windows 10 and Windows 11.
When Should You Factory Reset Windows?
A reset is the right solution when:
- PC is extremely slow despite trying optimization methods
- Persistent errors, crashes, or BSODs (Blue Screen of Death)
- Virus or malware infection that won't fully clear
- Selling or giving away the computer
- Windows won't boot properly
- Major software corruption after a failed update
⚠️ Before you reset: Back up all important files to an external drive or cloud storage. Even "keep my files" resets remove installed apps and settings.
Step 1: Back Up Your Data
Always back up before resetting, even if you plan to keep your files.
What to back up:
- Documents, photos, videos (Desktop, Documents, Downloads, Pictures folders)
- Browser bookmarks (export from Chrome/Firefox settings)
- Email data if using a desktop client (Outlook .pst file)
- Game saves (usually in Documents or AppData)
- Software license keys (use Belarc Advisor to export)
- Wi-Fi passwords (Settings → Network → Wi-Fi → Manage known networks → Show)
💡 Tip: Use Google Drive, OneDrive, or an external USB drive. A 32 GB flash drive is enough for most home users.
Method 1: Reset This PC — Keep My Files
This option reinstalls Windows but keeps your personal files. All installed programs will be removed. Takes 30–60 minutes.
Windows 11:
- Open Settings (
Win + I) - Go to System → Recovery
- Click "Reset PC" next to "Reset this PC"
- Choose "Keep my files"
- Choose how to reinstall Windows: "Cloud download" (fresher, needs internet) or "Local reinstall" (faster, no internet needed)
- Review the list of apps that will be removed
- Click "Reset" and wait 30–60 minutes
Windows 10:
- Settings → Update & Security → Recovery
- Under "Reset this PC", click "Get started"
- Choose "Keep my files" and follow the same steps
Method 2: Full Reset — Remove Everything
This option wipes your entire drive and reinstalls Windows fresh. Use this before selling your PC or for maximum cleanup. Takes 1–2 hours.
- Follow the same steps as Method 1
- At the choice screen, select "Remove everything"
- You'll be asked: "Just remove my files" or "Remove files and clean the drive"
- For selling the PC: choose "Remove files and clean the drive" (this overwrites data, making recovery nearly impossible)
- For personal use: "Just remove my files" is faster and sufficient
- Click "Reset" and wait
⚠️ This is irreversible. Once you click Reset with "Remove everything", all data is gone. Make sure your backup is complete before proceeding.
Method 3: Clean Install via USB Drive
The most thorough option. Downloads fresh Windows directly from Microsoft and installs it, bypassing any existing system files. Best for heavily infected or corrupted systems.
What you need:
- A USB drive with at least 8 GB of space
- A working internet connection on the PC you're using to create the USB
- Your Windows product key (usually on a sticker on your PC, or linked to your Microsoft account)
Steps:
- On any working PC, download the Media Creation Tool from Microsoft's website (search "Windows 11 download" on microsoft.com)
- Run the tool and choose "Create installation media for another PC"
- Select language, edition (Windows 11 Home/Pro), and architecture (64-bit)
- Select "USB flash drive" and choose your USB drive
- Wait for download and creation (15–30 minutes)
- Insert the USB into the target PC and restart
- Press
F2,F12,Del, orEscduring boot to enter BIOS (key varies by manufacturer) - Set USB as the first boot device and save
- Follow the Windows setup wizard to install
After the Reset: Setup Checklist
Once Windows is reinstalled, work through this checklist:
- ✅ Run Windows Update — install all available updates
- ✅ Install drivers (graphics, audio, network) — check manufacturer's website
- ✅ Install antivirus
- ✅ Restore your backed-up files
- ✅ Reinstall essential apps (browser, Office, etc.)
- ✅ Configure Windows settings and power plan
- ✅ Disable unnecessary startup apps

Troubleshooting Common Reset Issues
"There was a problem resetting your PC"
This usually means the Windows Recovery Environment is damaged. Use Method 3 (USB clean install) instead.
Reset Stuck at a Percentage
Wait at least 2 hours before assuming it's frozen. If truly stuck: hold the power button to force shutdown, restart, and try again. If it fails repeatedly, use the USB method.
PC Won't Boot After Reset
Power off, then on. If it still won't boot, you may need to access Advanced Startup Options: hold Shift while clicking Restart, then Troubleshoot → Reset this PC.
Don't Want to Risk It Yourself?
I'll perform a complete Windows reinstall remotely — backup, clean install, driver setup, and app restore.
All done safely in 2–3 hours via AnyDesk.
Conclusion
For most users, Method 1 (Reset this PC → Keep my files) is the best balance of thoroughness and convenience. It takes under an hour, keeps your documents, and fixes most software problems. If you're selling the PC or dealing with a serious virus, go with Method 2 or 3. Still unsure which to choose? Message me on Telegram and I'll advise for your specific situation.
