A read-only prompt for Claude Code on Windows 11

Is your PC sending your Wi-Fi passwords to Microsoft? Check in one prompt.

In the reel, Claude Code caught this laptop logging every Wi-Fi password it ever saved and sending it to Microsoft. Calling that stealing is a stretch. It is a Windows backup feature, opt-in but on by default in Windows 11. The passwords travel encrypted, and Microsoft holds the keys. Paste the prompt below into Claude Code on your own PC to see what yours is doing, then switch it off in Settings if you want to.

What the prompt asks Claude to find

Whether your PC backs up your Wi-Fi to your Microsoft account, and how to stop it.

  • Whether your PC is set to back up your Wi-Fi to Microsoft
  • Which Wi-Fi networks your PC has saved
  • Proof from your own PC that the sync is installed and scheduled to run
  • When your PC sent Wi-Fi records to Microsoft
  • A plain answer: is your Wi-Fi backed up to Microsoft, since when, and how to turn it off

Two steps: check, then decide

Paste the prompt and read what Claude Code finds. If you want the backup off, it is one switch in Settings. This is the prompt the reel promised.

Claude Code on your own Windows 11 PC. The traffic capture in step 6 of the prompt also needs Wireshark, and Claude skips it if you do not have it.

  1. 01

    Open Claude Code on your own Windows 11 PC and paste this prompt. It tells Claude to stay read-only: show you what it finds, explain it, and change or send nothing. Steps 1 to 4 of the prompt use commands built into Windows, step 5 reads a database file Windows keeps, and the optional traffic capture in step 6 needs Wireshark.

    Paste into Claude Code

    You're my Windows privacy investigator. Read-only: don't change or send anything. Show me what you find and explain it.

Check whether this PC is syncing my saved Wi-Fi networks and passwords to my Microsoft account:

1. Windows backup setting: is "Remember my preferences" on?
   Settings > Accounts > Windows backup. Tell me its state.
2. My saved Wi-Fi profiles and their passwords:
   netsh wlan show profiles
   netsh wlan show profile name="<each name>" key=clear   (look at Key Content)
3. The sync component:
   (Get-Item C:\Windows\System32\WiFiCloudStore.dll).VersionInfo | fl FileDescription,CompanyName,FileVersion
4. The scheduled tasks that drive it:
   Get-ScheduledTask -TaskPath '\Microsoft\Windows\WlanSvc\' | ft TaskName,State
5. The upload records (Windows Timeline / ActivitiesCache.db): look for AppId Microsoft.Credentials.WiFi
   entries and their upload times.
6. If I have tshark or Wireshark, capture TLS to activity.windows.com and show me when credential sync fires.

Then summarise: is my Wi-Fi being backed up to Microsoft, since when, and exactly how I turn it off.

    Your part: approve the commands Claude asks to run, then read its summary. If Claude Code runs as administrator, step 2 of the prompt also shows your saved Wi-Fi passwords in the session.

  2. 02

    Turn it off, if you want to. Open Settings, go to Accounts, then Windows backup, and switch off Remember my preferences. It is a backup and sync convenience, so the call is yours.

    Settings > Accounts > Windows backup > Remember my preferences: Off

    Your part: decide. You can do this without Claude Code. With it on, Windows backs up your preferences, saved Wi-Fi included, to your Microsoft account and syncs them to your other devices.

This is the prompt the reel promised. Two of its checks were run on a Windows 11 PC on 19 October 2026: WiFiCloudStore.dll read "Windows WiFi Sync Provider DLL" from Microsoft Corporation, and WlanSvc listed two scheduled tasks.

Questions people ask

  • Is Microsoft stealing my Wi-Fi passwords?

    Stealing is a stretch, and we said so in the reel. It is a Windows backup feature, opt-in but on by default in Windows 11. The passwords go up encrypted, and Microsoft holds the keys. Keeping it on is your call.

  • Will the prompt change anything on my PC?

    It is written not to. It tells Claude Code to stay read-only, its checks read settings, files and lists, and step 6 only watches network traffic. Turning the backup off is a step you take yourself, in Settings.

  • Does it work on a Mac?

    No. Every check in it looks at a part of Windows, and it is written for Windows 11.
