Disable a Windows Service in Rescue Mode
If a Windows service is causing problems — for example, preventing the operating system from starting correctly — you can manually disable it via the Windows Registry in the rescue environment.
Warning: Editing the Windows Registry can cause severe system damage if done incorrectly. Make sure you have a current backup before proceeding.
Prerequisite: Your server must be booted into the Windows Rescue System and connected via VNC. The VNC session password must be exactly 8 characters long. → Starting rescue mode
Step 1: Open the Registry Editor
On the rescue desktop, open the Registry Editor via Start → Run and type regedit.
Step 2: Locate the Service
In the left-hand pane of the Registry Editor, navigate to the following key:
Find and click the name of the service you want to disable in the list of subkeys.
Step 3: Set the Start Type to Disabled
In the right-hand pane, find the value named Start and double-click it. Change the value data to 4 to disable the service.
| Value | Start Type |
|---|---|
| 2 | Automatic |
| 3 | Manual |
| 4 | Disabled — set the service to this value |
Step 4: Reboot
After making the change, close the Registry Editor.
Do not reboot from within the rescue environment. Go to your PowerPanel and cancel rescue mode — this reboots the server back into its normal Windows operating system. → Cancelling rescue mode
