Simplify windows setup instructions (#2114)

Browse source 
* Simplify /windows to the bare minimum. Also remove the
  /windows/tailscale.reg endpoint as its generated file is no longer
  valid for current Tailscale versions.
* Update and simplify the windows documentation accordingly.
* Add a "Unattended mode" section to the troubleshooting section
  explaining how to enable "Unattended mode" in the via the Tailscale
  tray icon.
* Add infobox about /windows to the docs

Tested on Windows 10, 22H2 with Tailscale 1.72.0

This documentation has the goal of showing how a user can use the official Windows [Tailscale](https://tailscale.com) client with `headscale`. This documentation has the goal of showing how a user can use the official Windows [Tailscale](https://tailscale.com) client with `headscale`.
## Add registry keys
To make the Windows client behave as expected and to run well with `headscale`, two registry keys **must** be set:
- `HKLM:\SOFTWARE\Tailscale IPN\UnattendedMode` must be set to `always` as a `string` type, to allow Tailscale to run properly in the background
- `HKLM:\SOFTWARE\Tailscale IPN\LoginURL` must be set to `<YOUR HEADSCALE URL>` as a `string` type, to ensure Tailscale contacts the correct control server.
You can set these using the Windows Registry Editor:
![windows-registry](./images/windows-registry.png)
Or via the following Powershell commands (right click Powershell icon and select "Run as administrator"):
```
New-Item -Path "HKLM:\SOFTWARE\Tailscale IPN"
New-ItemProperty -Path 'HKLM:\Software\Tailscale IPN' -Name UnattendedMode -PropertyType String -Value always
New-ItemProperty -Path 'HKLM:\Software\Tailscale IPN' -Name LoginURL -PropertyType String -Value https://YOUR-HEADSCALE-URL
```
The Tailscale Windows client has been observed to reset its configuration on logout/reboot and these two keys [resolves that issue](https://github.com/tailscale/tailscale/issues/2798).
For a guide on how to edit registry keys, [check out Computer Hope](https://www.computerhope.com/issues/ch001348.htm).
## Installation ## Installation
Download the [Official Windows Client](https://tailscale.com/download/windows) and install it. Download the [Official Windows Client](https://tailscale.com/download/windows) and install it.
When the installation has finished, start Tailscale and log in (you might have to click the icon in the system tray). ## Configuring the headscale URL
The log in should open a browser Window and direct you to your `headscale` instance. !!! info "Instructions on your headscale instance"
An endpoint with information on how to connect your Windows device
is also available at `/windows` on your running instance.
Open a Command Prompt or Powershell and use Tailscale's login command to connect with your headscale instance (e.g
`https://headscale.example.com`):
```
tailscale login --login-server <YOUR_HEADSCALE_URL>
```
Follow the instructions in the opened browser window to finish the configuration.
## Troubleshooting ## Troubleshooting
### Unattended mode
By default, Tailscale's Windows client is only running when the user is logged in. If you want to keep Tailscale running
all the time, please enable "Unattended mode":
- Click on the Tailscale tray icon and select `Preferences`
- Enable `Run unattended`
- Confirm the "Unattended mode" message
