Error Code 49 – What is it?
Error Code 49 is a common device driver error that users encounter on any Windows 2000 and later operating system versions.
The error occurs when the connected peripheral devices fail to function properly due to an overload of the system hive’s size.
The error when prompted pops up on your screen with the following message:
"Windows cannot start new hardware devices because the system hive is too large (exceeds the Registry Size Limit). (Code 49)”
The error causes unattached devices to be displayed on the system hive list.
Error Code 49 mainly results from problems in Windows registry system files; the system hive in the Windows registry exceeds its size limit.
The system hive is part of the Windows registry and it is where files regarding devices are contained along with user preferences and applications.
The devices will not work until the system hive size is brought back to normal levels.
Further Information and Manual Repair
There are several ways you can use to fix your error code. Here are the following.
Method 1 – Uninstall unused devices
One of the best ways to address the error code is to uninstall the unused devices which are listed on your computer’s system hive. To do this:
- Log in using an Administrator account
- Click the Start button and then click ‘Run’
- In the box, enter the command:
- "set devmgr_show_nonpresent_devices=1 cd%SystemRoot%System32 exit"
and click enter
- Open Device Manager, click ‘View’, and then choose ‘Show hidden devices’ to see unused devices.
- When you can see the list, click on the device you want to uninstall by selecting the ‘Driver’ tab and then select ‘Uninstall’.
- After uninstall is complete, restart your computer.
Method 2 – Use System Restore
If the error still persists, you can use system restore to eliminate the problem. Here is how you can do so:
- Log in using an Administrator account
- Click ‘Start’ button and select All Programs > Accessories > System Tools > System Restore
- Click ‘Restore my computer to an earlier time’ and click ‘Next’
- Select the last Windows restore point from the ‘On this list, click a restore point’ list, and click ‘Next’
- Click ‘Next’ on the confirmation window to proceed
- Restart your PC after restoration is complete
By restoring the system via a last saved system checkpoint, you can obtain undamaged Windows system files that can help avert the error code.
Method 3 – Manually uninstall and reinstall the device driver
If using system restore does not work in resolving the error code either, 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 results in 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.
