Error Code 40 is a device driver error that users encounter on any Windows 2000 and later operating systems. It occurs when the peripheral device that you connect to your PC cannot be accessed due to a change in the system registry.
This is due to the presence of invalid sub-keys of the device driver in the system registry.
It is a common error that users come across and appears on your PC with either of the following messages:
“Information in the registry entry for this driver is invalid”
OR
"Windows cannot access this hardware because its service key information in the registry is missing or recorded incorrectly. (Code 40)"
Error CausesAs mentioned above, the error code is triggered when the device driver’s invalid sub-keys appear in the registry, effectively changing it. This happens when the windows system files get damaged due to the following factors:
Factors such as incomplete installations or uninstallations or an improper system shut down can cause files to become damaged that threaten the health of your computer.
Removing viruses from the computer is also another factor as it removes the entries in the Windows system files which contain the viruses including spyware or malware
Fixing Error Code 40 is similar to fixing other device manager error codes. Here are a few methods you can try.
You can use system restore to eliminate the problem. Here is how you can use it:
By restoring the system via a last saved system checkpoint, you can obtain undamaged Windows system registry files that can help avert the error code.
If using system restore also does not work in removing the error code, you may have to resort to manually uninstalling and then reinstalling the device driver causing the problem.
This would be necessary since the remaining incomplete files due to a partial removal or installation of programs is what contributes to the error code. By uninstall and reinstalling the device driver program, it would lead to the completion of the files.
You can do this by firstly logging in as Administrator and open Device Manager. Select the device that is causing the problem and double click it and make sure that the peripheral is connected properly to the PC. Upon opening, click on the ‘Driver’ tab and then select ‘Update Driver’.
Make sure to refer to the system documentation that you received with your PC or computer to check for the motherboard details and driver specifics.
Manually uninstalling and reinstalling the driver will do the trick, however, it may be time-consuming especially when you would have to resort to your hardware user manual.
Therefore, using a program such as DriverFIX can save you a lot of time and frustration in having your device work properly on your computer.

Some users wanting to upgrade to Windows 10 from Windows 7 or Windows 8.1 experienced errors with installation. One of these errors is CPU Not Compatible. When you click and run the “Get Windows 10” from your system tray bar, you’ll receive the “CPU is not compatible with Windows 10” error. When this happens, it might be good to check if there’s a bug or if your NX feature (a requirement for the Windows 10 installation) is enabled.
Error CausesThe “CPU is not compatible with Windows 10” error normally occurs when:
To successfully upgrade to Windows 10, your CPU must support Physical Address Extension (PAE), SSE2, and NX features. If any of these features are not activated on your system, it’ll cause the CPU not compatible error. However, some users still reported experiencing this error even though their CPU has these features activated. Normally, this is due to the bug that Windows acknowledged.
If any of these two scenarios apply to your computer, the following methods will help you fix the problem:
The bug applies to some Windows 7 and Windows 8.1 systems. The bug occurs when the “Get Windows 10” app fails to recognize CPUs as being compatible. This produces a false negative result with a message, “Here’s why Windows 10 cannot be installed on this PC: The CPU isn’t supported”. To fix this bug, Microsoft released an update.
Unfortunately, the patch update (KB2976978 for Windows 8/8.1 and KB2952664 for Windows 7 SP1) to fix the bug may not be automatically downloaded to your computer. If this is the case, you need to verify first if the patch was installed correctly. To do this, follow the steps below:
A major requirement for Windows 10 upgrade is for the CPU to have Physical Address Extension (PAE), SSE2, and NX features enabled on your system. If you receive the CPU not compatible error, one possible cause is that any of the mentioned features are not available OR not enabled on your system. Here’s how you can fix this:
If changing the settings in your BIOS doesn’t do the trick, your final option is to force enable the NX bit in your Windows system. However, this is only applicable IF and ONLY IF your CPU does support it. To force enable NX bit, do the following:
