I Turned Off the IP Helper in Windows 10

Disabling IP Helper does not control preboot video or keyboard input, so restore the display first and then re-enable the service after Windows becomes accessible.

IP Helper concerns local TCP/IP configuration and networking transition technologies; it is not responsible for monitor output or keyboard operation before Windows loads.^1^ A complete absence of the manufacturer/BIOS logo therefore points to a separate display or hardware-startup problem rather than a disabled IP Helper service.

1. Determine whether the PC produces any video

1. Shut down the PC by holding its power button for about 20 seconds.
2. Disconnect unnecessary USB devices, leaving only the monitor and a basic wired keyboard.
3. Reseat the monitor cable at both ends and verify that the monitor is using the correct HDMI/DisplayPort input.
4. Test another cable, monitor/TV, and graphics port if available. These are Microsoft’s first recommended checks for a no-signal or blank-screen condition.^2^
5. Start the PC and watch specifically for the manufacturer or BIOS/UEFI logo.

If no logo or firmware screen ever appears: Windows has not yet reached a point where changing a Windows service could affect the display. If alternative cables, displays, and ports also show no signal, the GPU, RAM, power supply, or motherboard needs hardware diagnosis. If this is a desktop with a separate graphics card, ensure the monitor is connected to the graphics card rather than the motherboard unless the processor supports integrated graphics.

If the logo appears and the screen becomes blank only when Windows starts: try these display recovery shortcuts:

• Press Windows + Ctrl + Shift + B to reset the graphics driver.
• Press Windows + P, press P again, and then press Enter to cycle display modes.
• Press Ctrl + Alt + Delete and check whether the security screen appears.^3^

2. Use System Restore instead of retrying Safe Mode

Since the earlier Safe Mode attempt did not help, use Windows Recovery Environment (Windows RE) and restore the configuration from before the service change:

1. Turn on the PC and wait for the Windows or manufacturer logo.
2. Hold the power button until it shuts down before Windows finishes loading.
3. Repeat that interruption once.
4. Start the PC a third time. Windows should enter Automatic Repair.
5. Select Advanced options > Troubleshoot > Advanced options > System Restore.
6. Select a restore point created before IP Helper was disabled.

Windows RE normally opens after two interrupted starts and includes System Restore, Startup Repair, Startup Settings, and Command Prompt. Some tools may request the BitLocker recovery key.^4^

If the PC never produces video even in firmware or Windows RE, do not continue performing blind forced shutdowns; move to hardware testing or professional repair.

3. Re-enable IP Helper once Windows is accessible

Open Services with an administrator account:

1. Press Windows + R.
2. Enter services.msc.
3. Double-click IP Helper.
4. Change Startup type from Disabled to Automatic.
5. Select Apply > Start > OK.
6. Restart Windows.

Alternatively, open Command Prompt as administrator and run:

sc.exe config iphlpsvc start= auto
sc.exe start iphlpsvc
sc.exe query iphlpsvc

The space after start= is required by sc.exe; a disabled service must have its start type changed before it can be started.^5^ The final command should report the service as RUNNING.

Windows 10 reached end of support on October 14, 2025. After recovery, plan an upgrade to a supported Windows version if the hardware is eligible.^6^
