Before You Start: Windows 11 System Requirements

| Component | Minimum Requirement |
|---|---|
| Processor | 1 GHz, 2+ cores, 64-bit compatible |

Step 1: Backup Your Data First (Critical!)
Even though the upgrade process is designed to keep your files, always back up your important data first. Here's how:
Quick Backup Checklist:
- Documents folder: Copy to external drive or cloud storage
- Desktop files: Often forgotten—check for important files
- Pictures & Videos: Copy entire folders to backup location
- Browser bookmarks: Export from Chrome, Firefox, Edge
- Game saves: Check AppData folders or use Steam Cloud
- Software license keys: Note down product keys for reinstallation
Backup Options:
☁️ OneDrive
Sync Documents, Desktop, and Pictures to Microsoft cloud (free 5GB)
💾 External Drive
Copy files to USB drive or external HDD for offline backup
🔧 Windows Backup
Use built-in Windows Backup and Restore (search in Start)
Step 2: Check PC Compatibility
Use Microsoft's official PC Health Check tool to verify your system is compatible:
- 1. Download PC Health Check from Microsoft's website
- 2. Run the application and click "Check now"
- 3. Review the results—it will tell you if you're ready for Windows 11
Pro Tip: TPM 2.0 Issues
If PC Health Check says "TPM 2.0 not found," it might just be disabled in your BIOS. Check your motherboard settings to enable it.
Step 3: Choose Your Upgrade Method
There are three main ways to upgrade to Windows 11 without losing data:
Method A: Windows Update (Recommended)
Best for compatible PCs • Automatic • Keeps everything
Method B: Installation Assistant
When Windows Update isn't offering the upgrade yet
Method C: In-Place Upgrade via ISO
More control • Can bypass some requirements

The entire process takes 30-60 minutes depending on your internet speed and hardware.

Your Files Are Safe
When you choose "Keep personal files and apps," Windows preserves your Documents, Pictures, Desktop files, and installed programs.
After the Upgrade: What to Check
Once Windows 11 is installed, run through this post-upgrade checklist:
- Verify your files: Check Documents, Desktop, Pictures folders
- Check installed programs: Make sure your apps still work
- Update drivers: Go to Settings → Windows Update → Advanced options → Optional updates
- Check activation: Settings → System → Activation (should show "Windows is activated")
- Run Windows Update: Install any pending updates for Windows 11
Troubleshooting Common Upgrade Issues
"This PC doesn't meet requirements"
Solution: Check if TPM 2.0 and Secure Boot are enabled in BIOS. Many PCs have these disabled by default. Restart, enter BIOS (usually F2, DEL, or F12), and enable them.
"Not enough disk space"
Solution: Windows 11 needs at least 64GB free. Run Disk Cleanup, delete temp files, or move files to external storage before upgrading.
"Upgrade stuck or frozen"
Solution: Be patient—upgrades can take 1-2 hours on older hardware. If stuck for more than 3 hours, force restart and try the Installation Assistant method.
"Windows not activated after upgrade"
Solution: If you upgraded from activated Windows 10, Windows 11 should activate automatically. If not, you may need a new Windows 11 product key—get one here for $33.99.
