Restart in safe mode and keep working there

Start a Windows device remotely in safe mode with networking and keep working there — the start after that is normal again.

What it is for

Stubborn malware, a driver that hangs at start-up, a service that will not stop — that is what Windows safe mode is for. BrowserDesk keeps running there and your window reconnects by itself. The start after that is normal again; the device never stays in safe mode for good.

What you need

  • A Windows device with the BrowserDesk service installed (C4), BrowserDesk from version 20261010.37.
  • Cloud or an own relay with access without consent. After the restart nobody sits at the sign-in screen who could agree.
  • The control right in the session — or access to the device in the console.

How to do it

From the session

  1. Menu Verwaltung (Management) → Neustart im abgesicherten Modus (Restart in safe mode; in the browser in the selection "System-Infos / Energie…").
  2. Confirm with Ja (Yes).
  3. Wait. Above the picture it says "Gerät startet im abgesicherten Modus mit Netzwerk – Verbindung wird wiederhergestellt …" (device is starting in safe mode with networking – connection is being restored). Your window waits up to 7 minutes on purpose, then continues with a notice.
  4. Work in safe mode. The picture comes through Windows' basic display driver.
  5. Back: Normal neu starten (Restart normally — shown while the device runs in safe mode) — or simply Neustart (Restart).

From the console

  1. Devices → the device's menu (⋮) → group Restart → Restart in safe mode….
  2. Confirm with Restart. The console reports "Request sent – the device checks and replies." and then the result.
  3. Back: Restart normally… in the same menu.

How you know it worked

  • The picture comes back.
  • The Verwaltung menu now offers Normal neu starten instead of Neustart im abgesicherten Modus.

What the other side sees

Windows briefly announces "BrowserDesk: Neustart im abgesicherten Modus mit Netzwerk" and restarts after a few seconds. If the request comes from the console, a confirmation may appear at the device first, depending on the device's settings — as when running a script.

Good to know

  • One time only: as soon as it starts in safe mode, BrowserDesk sets the next start back to normal — even if BrowserDesk itself does not come up there.
  • Normal neu starten also clears a safe start that someone set by hand (e.g. with msconfig).
  • In safe mode BrowserDesk runs no updates and no watchdog, and third-party antivirus does not run either.
  • If Windows lacks something needed for networking in safe mode, BrowserDesk changes nothing and does not restart — otherwise the device would end up without network.
  • Domain computers: signing in with a domain account usually works; without a reachable domain controller only with cached credentials.
