Quick answer: Use the netsh wlan export command or Advanced Password Recovery Suite to back up all saved WiFi passwords before reinstalling Windows. After a clean install, all network profiles are deleted and must be re-entered manually.
Why WiFi Backup Matters
Most users remember to back up their files but forget about WiFi passwords. After a clean install, Windows deletes every saved network profile. If you have 10+ networks saved (home, office, phone hotspot, hotels, friends' houses) you will need to reconnect to each one from scratch. For networks where you no longer have the router sticker, or locked corporate networks, this can be a serious problem.
Method 1: Command Prompt Export
Steps:
- Open Command Prompt as administrator
- Run:
netsh wlan export profile key=clear folder=C:\WiFiBackup - Copy the WiFiBackup folder to a USB drive before formatting
Method 2: Advanced Password Recovery Suite
For a single readable CSV, TXT or HTML instead of multiple XML files, Advanced Password Recovery Suite exports all WiFi passwords in one step alongside browser passwords and software keys.

After Reinstalling: How to Reconnect
