4 Methods of Fixing Error Code 49

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.

Solution

driverfix boxError Causes

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:

  1. Log in using an Administrator account
  2. Click ‘Start’ button and select All Programs > Accessories > System Tools > System Restore
  3. Click ‘Restore my computer to an earlier time’ and click ‘Next’
  4. Select the last Windows restore point from the ‘On this list, click a restore point’ list, and click ‘Next’
  5. Click ‘Next’ on the confirmation window to proceed
  6. 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.

Method 4 – Use software to automatically download the driver

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.

DriverFIX, with its user-friendly approach to help you fix your PC issues, comes with an integrated database that detects which drivers you need to reconfigure within just a few seconds and downloads it automatically.

UEFI Firmware settings goes missing
When it comes to booting an operating system on a computer, one of the most essential pieces of software you can use is the UEFI. In fact, a lot of users now prefer to use UEFI instead of BIOS. It also depends on whether the UEFI or the BIOS is supported on the motherboard. Recently, a number of users reported an issue with UEFI where they were unable to find it under the Advanced Options screen where it’s supposed to be located. The missing UEFI Firmware settings in the Advanced Options could be caused by several reasons. It is possible that the access to the UEFI menu is blocked or it could also be due to the Extra Fast Startup feature being enabled. It is also possible that the operating system is installed in Legacy mode. There are several options to try to fix this issue. You need to check if your computer supports UEFI or you could also try to disable Fast Startup or bypass the Extra Fast Startup feature. You can also use a boot to UEFI shortcut as well as check the CMOS battery.

Option 1 – Try checking if your computer supports UEFI

The first thing you have to do is to verify if your computer supports UEFI. If your computer does not support UEFI, then it’s no wonder why you don’t see the UEFI Firmware settings in the Advanced Options.

Option 2 – Try turning off Fast Startup

  • First, boot your computer in Safe Mode.
  • Once your computer is booted in Safe Mode, tap the Win + R keys to open the Run dialog box and type in “control” to open the Control Panel.
  • Next, click on the Hardware and Sound section and click on Power Options.
  • Afterward, select the “Choose what the power buttons do” option from the left side menu pane.
  • Now click on Change settings that are currently unavailable and uncheck the entry that says, “Turn on fast startup (Recommended)”.
  • Then click on Save Changes and restart your computer and see if it has fixed the problem or not.

Option 3 – Try bypassing the Extra Fast Startup feature

As mentioned, the missing UEFI Firmware settings could be due to the Extra Fast Startup feature. To fix it, you have to disable this feature. All you have to do is tap and hold the Shift key and click on the Shutdown button from the Start button. This will boot your PC with the UEFI booting from the beginning and then use the hotkey for your motherboard to boot into the UEFI setup.

Option 4 – Try using a boot to UEFI shortcut

  • Right-click on any empty space on your Desktop and select New > Shortcut.
  • This will open a new mini window. And here, you have to type this in the text field: shutdown /r /fw
  • After that, click on Next and name the desktop shortcut and then click on Finish.
  • Next, right-click on the newly created shortcut and select Properties.
  • Click on the Advanced button and select the “Run as administrator” option.
  • Now click OK to save the changes made. Each time you execute this shortcut, your computer will automatically be booted to the UEFI Firmware Settings.

Option 5 – Try to check the CMOS battery

Another thing you can do is check the CMOS battery physically on the motherboard and see if it has to be replaced since a damaged CMOS battery can also cause the issue with the missing UEFI Firmware settings.

Option 6 – Set your computer from Legacy to UEFI

If applicable, you can try to set your computer from Legacy to UEFI to resolve the problem.
  • In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
  • After that, execute this command: mbr2gpt.exe /convert /allowfullOS
  • Now, wait until the process is completed since you can track its process on your screen.
  • Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
  • Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
  • Now select the UEFI Firmware Settings. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to UEFI and then save the changes you’ve made. After that, your computer will restart.

How to Fix Error Code 0xc0000142

What is Error 0xc0000142?

Error 0xc0000142 can occur in any of the Windows versions and usually occurs when an application fails to properly initialize.

This error can be critical for a computer as it signifies that the system is unstable. Error 0xc0000142 can cause slow performance in a PC, system freeze, startup and shutdown issues, blue screen and errors in installation.

Solution

Restoro box imageError Causes

Windows/Application Error 0xc0000142 can occur because of a number of reasons.

When a computer is an overload with data, or when system files get broken or missing, this error can occur and will result in startup and shutdown issues as well as the blue screen. Another reason, and one which is quite common, is improper computer maintenance.

This will cause a PC to perform slow, system freezes, and installation errors. This error displays ‘failed to initialize’ on either a Windows error box or the blue screen of death.

Further Information and Manual Repair

Error 0xc0000142 can occur at any time, but there are many ways to resolve it. For instance:

1) Clean the Registry

A corrupted registry is one of the major reasons why this error occurs. The registry is used by Windows to store information and settings on the computer, which is why it has a large database.

This database contains emails, wallpapers, saved passwords and much more in ‘file path references’. These allow Windows to run the common files in your system. A registry cleaner can fix any errors in the registry database.

2) Malware Scan

Viruses can cause certain applications to not function properly. Hence, download a strong antivirus and run a deep scan on your system and remove any potential infections and spyware.

3) Reinstall Applications

Non-critical applications in a computer are those that are installed by the user. If error 0xc0000142 displays in any of your installed programs, then you should reinstall these programs. Often applications have damaged or corrupted files which can slow them down. To resolve this, follow these steps:

  • From Start, click on Control Panel
  • Go to Add/Remove Programs and uninstall the programs
  • Restart your PC and reinstall the program

The third step is not recommended in case the error is caused by cmd.exe

4) Repair Windows

If the error is still on display despite following the previous steps, then you can repair Windows. This process allows Windows to retain all your data and information by simply replacing the program files and settings with fresh ones. This can stop error 0xc0000142 by allowing the programs access to use necessary files smoothly and effectively.

If you cannot resolve the error in any of these steps, then there is another way to do so if you have a computer that runs the Microsoft Internet Security and Acceleration (ISA) Server 2000. Follow these steps in order to resolve it:

  • Make sure that in Program Files and Microsoft ISA Server, a Clients folder exists. The ISA Server service will run on this folder
  • Confirm that Administrators and SYSTEM have Full Control assigned in the Program Files/Microsoft ISA Server/Clients folder
  • Confirm that Msplat.txt file is in the Clients folder. You can copy this file from other ISA Server computers if it is missing
  • If the Clients folder is damaged or is missing, or if you can’t copy the Msplat.tct file from another ISA Server computer, then reinstall the ISA Server 2000

isapnp.sys, gv3.sys, storahci.sys, myfault.sys
One of the common causes of Blue Screen of Death or BSOD errors is system driver files due to varying reasons. So if you encounter a Stop error caused by some system driver files such as isapnp.sys, gv3.sys, storahci.sys, or myfault.sys, on your Windows 10 PC, then this post should help you fix the problem. These system driver files are associated with different error codes. The isapnp.sys file is related to the following error codes:
  • SYSTEM SERVICE EXCEPTION
  • PAGE FAULT IN A NONPAGED AREA
  • KERNEL DATA INPAGE
  • SYSTEM THREAD EXCEPTION NOT HANDLED
  • IRQL NOT LESS EQUAL
