# First, install without internet and local account (disable WLAN from BIOS and Shift+F10, OOBE\BYPASSNRO)
# Second, Block ALL traffic in firewall, set default to block and set enabled services to block too
# Third, be aware this fucker is enabling firewall rules automatically after you enable WLAN. You want to block those too, but idk how to avoid Windows setting their own rules without permission. Fucking crazy this is rules appear in firewall without consent.
# ! Run the commands below, then restart and then allow internet only.

### Things I didn't try/test: Use Advanced Privacy Tools

1. Download and run **[O&O ShutUp10++](https://www.oo-software.com/en/shutup10)**.
   - Apply all "Recommended" and "Recommended and somewhat recommended" settings.
2. Install **[WPD](https://wpd.app/)** for additional telemetry blocking.


### Old privacy hardening notes below

# Disable all networking except for programs you need it for.

# Alternatively try these and use a good firewall, don't allow unwanted sites.
