I have an error 1450: "Insufficient system resources exist to complete the requested service" when running `sc start MyDriverName`

Question

I have an error 1450: "Insufficient system resources exist to complete the requested service" when running sc start KMDFDriverIOCTL
(KMDFDriverIOCTL - is my driver that i wrote with wdk).

The last time the driver worked was yesterday
I have disabled driver test signature verification and am trying to run my driver.

My steps:

1. Run cmd as Administrator
2. Enter next command: sc start KMDFDriverIOCTL

cmd output:

[SC] StartService: error: 5:
Access is denied.

3. Trying to run the driver a second time: sc start KMDFDriverIOCTL

cmd output:

[SC] StartService: error: 1450:
Insufficient system resources exist to complete the requested service.

I got error 1450 on each successive attempt, but error 5 only came up on the first attempt to run the driver.

How can i solve this problem? Thanks in advance.

Hello The errors you’re encountering are related to system permissions and resources. Let’s address them one by one:   Error 5: Access is Denied This error typically occurs when the command or application doesn’t have the necessary privileges. Here are some steps you can try:   1.Run Command Prompt as an Administrator: Right-click on Command Prompt and select “Run as Administrator”. This will give you elevated privileges. 2.Change User Account Control Settings: If your user account doesn’t have the necessary privileges, you might need to change your account type to an administrator account.   Error 1450: Insufficient System Resources Exist to Complete the Requested Service This error can occur due to several reasons, including outdated drivers, insufficient memory, or registry issues. Here are some potential solutions:   1.Update Your Drivers: Outdated drivers can sometimes cause this error. Make sure all your device drivers are up-to-date. 2.Check Registry Settings: There are certain registry settings that can help resolve this issue. However, be careful while editing the registry as it can have serious impacts on your system. 3.Free Up System Resources: Close any unnecessary applications to free up system resources. Also, consider increasing your system’s memory.

Hello! MaxIsTaken, I found a solution to this problem by thinking about debugging my driver. To debug the Windows kernel, you first need to configure Windows. The settings needed for this are described here https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/setting-up-local-kernel-debugging-of-a-single-computer-manually . In the "Setting Up Local Kernel-Mode Debugging" section, I followed steps 1 and 2, then rebooted my PC according to step 3:

1. Open a Command Prompt window as Administrator. Enter bcdedit /debug on
2. If the computer is not already configured as the target of a debug transport, enter bcdedit /dbgsettings local
3. Reboot the computer.

I was shocked when after rebooting the PC, my driver started working. But I don't understand why. Also, to avoid error 52 (bad sign), I run the PC with mandatory device driver signature verification disabled.

Hope this helps you
