Outlookの例外コードを修正する方法0xc0000005（フルガイド）

コンピュータが再起動し、システムメモリの問題のチェックを開始します。デフォルトで標準テストを実行しますが、詳細であるため、拡張バージョンを選択することをお勧めします。 F1 を押してオプションに移動し、拡張を選択して、 F10 を押します。

メモリの問題を特定するのに忙しい間は、PCを無人のままにしておくことができます。完了すると、Windows 10が正常に起動し、通知センターにスキャン結果が表示されます。別の解決策は MemTest86 で、これを使用して RAMストレステストを実行します。

14。ドライバーを確認してください

デバイスドライバが古くなっているか、オペレーティングシステムと互換性がない可能性があります。やがて、ファイルを開いたり、ゲームをプレイしたり、さまざまなアプリケーションを起動したりしようとすると、エラー0xc0000005が発生する可能性があります。デバイスとビデオドライバが廃止され、更新が必要かどうかを確認して、トラブルシューティングプロセスを開始します。

ドライバーを更新する方法：

1. 開始ボタンを右クリックして、デバイスマネージャー

に移動します

2. このグループを拡張するには、ディスクドライブの横にある小さな矢印をクリックします
3. ディスクを選択して右クリックし、ドライバーの更新
4. [ドライバーを自動的に検索する]をクリックします。 If you get the The best drivers for your device are already installed message, click Search for update drivers on Windows Update. But if you have already checked for system updates, there’s no need to do this again
5. Do the same for your video driver in the Display adapters category

Windows is rarely successful at finding and downloading drivers on its own. In fact, it’s more reliable to do this manually: find the name of your driver in the Properties section, visit the official website, download a newer version, then return to Device Manager to perform the update by selecting the Browse my computer for drivers option.

However, if you’re having a hard time trying to figure out which drivers are obsolete and where to download them from, it’s easier to use a driver update application. It scans your computer, finds obsolete drivers, locates newer versions on the web, and installs them to your computer. And it’s all performed automatically. Plus, you won’t risk getting incompatible drivers that might end up causing more harm to your PC.

How to roll back unsupported drivers:

1. Press Win key + R, type devmgmt.msc, and hit Enter
2. Choose the device with the unsupported driver, right-click it, and go to Properties
3. Select the Driver section
4. Click Roll Back Driver and follow the steps. If the button’s greyed out and you can’t click it, it’s not possible to make the rollback because there’s no previous driver version saved to your PC. You can skip this step

15. Run a malware scan

If your operating system has viruses, it’s no wonder that you keep getting error codes like 0xc0000005 when trying to use your computer. It’s time to use Windows Defender or any other third-party anti-malware solution installed, in order to find and eliminate any threats from your hard drive.

How to use Windows Defender:

1. Press the Win key, search for Windows Security, and launch this app
2. Go to Virus & threat protection
3. Choose Quick scan and click Scan now
4. If no threats are revealed after the quick scan, select Windows Defender Offline scan and click Scan now
5. Patiently wait while Defender runs the scan. You shouldn’t use your computer during this time since it will be slowed down. If Defender identifies any viruses, allow it to quarantine or remove the suspicious files. Meanwhile, any files you consider safe should be moved to the whitelist in order to exclude them from further scans

16. Temporarily turn off your antivirus

Depending on the third-party antivirus program you have installed, certain security settings might conflict with your computer configuration. In other words, your security program might block your access to your favorite applications due to safety issues.

To quickly put this theory to the test, temporarily disable your antivirus and then try to open the file or launch the application. If you can do so without any more errors, it means that you have to change your antivirus settings and add an exception for your files and applications. Whatever you do, don’t leave the antivirus powered off since you will leave your PC vulnerable to Internet dangers.

17. Temporarily disable your firewall

Your firewall controls which applications are allowed to access the Internet and which outside servers can reach your machine. Normally, an application makes an exception for itself in the system firewall as soon as you set it up. However, if that doesn’t happen on your computer because you or someone else changed firewall settings, you can end up with application errors like 0xc0000005.

Easily test this by deactivating your firewall:

1. Log in to Windows 10 with administrator rights
2. Press the Windows key, type Check firewall status, and hit Enter
3. Click Turn Windows Defender Firewall on or off on the left part of the window
4. Set Turn off Windows Defender Firewall at both Private network settings and Public network settings. Click OK

Try to launch the application or open the file that was giving you trouble before.

If you’re successful, restore firewall settings to default:

1. Search for firewall on your computer and open Firewall & network protection
2. Scroll down and click Restore firewalls to default
3. Click Restore defaults and Yes to confirm

If the 0xc0000005 error returns, add an exception for your app in the firewall:

1. Go back to Firewall & network protection
2. Click Allow an app through firewall
3. Click the Change settings button (you need admin rights)
4. Search for your app in the list. If it’s not there, click Allow another app, the browse your computer and add your application’s launcher file
5. Select your app from the list, check its box, then enable the Private and Public options next to it

18. Change Data Execution Prevention settings

Data Execution Prevention (DEP) is a security tool built into Windows 10, whose role is to protect memory pages by stopping applications from deploying malicious code. If the program you’re trying to launch has a behavior seen as malicious, DEP won’t let you access it. It could be the reason why you keep getting the 0xc0000005 violation error.

But you can make an exception for your app in Data Execution Prevention:

1. Press Win key + R, type sysdm.cpl, and press Enter to access System Properties
2. Go to the Advanced tab
3. At Performance, click the Settings button
4. Switch to the Data Execution Prevention tab
5. Select Turn on DEP for all programs and services except those I select
6. Click Add, open your application’s executable file, and click OK to confirm. You can do this for multiple programs. However, keep in mind that DEP can’t be turned off for certain programs
7. Click Apply and exit to the desktop
8. Try to open your program now

If you later wish to restore Data Execution Prevention settings to default, retrace the steps above to reach the Data Execution Prevention tab. Then, choose Turn on DEP for essential Windows programs and services only, and click Apply.

19. Disable the LoadAppInit_DLLs registry entry

Another way to fix the 0xc0000005 violation code error is by disabling the LoadAppInit_DLLs registry entry. Don’t worry about damaging computer settings since you will be creating a registry backup before changing anything, just in case you need to restore the original configuration later.

1. Click the Start button, search for regedit, and open Registry Editor
2. Open the File menu and click Export
3. Set a file name and destination, then click Save to create the registry backup file (.reg format)
4. Go to this location:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows

5. Find the LoadAppInit_DLLs entry and check that its Data is set to 0x00000000 (0). If it’s not, double-click the entry, set Value data to 0 and Base to Hexadecimal, then click OK
6. Exit Registry Editor

If you need to restore the previous registry settings for any reason, just double-click the.reg file you previously exported.

20. Repair the BCD file

If your system’s BCD (Boot Configuration Data) is malfunctioning, Windows might have trouble trying to process the files and settings required for launching programs. But you can repair the BCD file using a Windows installation media:

1. Connect an empty USB flash drive into your PC
2. Download Media Creation Tool from the official website
3. Start the application and follow the steps to set up a Windows installation media disk
4. Click the Start button and open the power menu
5. While holding down the Shift key, click Restart to boot Windows to the troubleshoot menu
6. Select Troubleshoot > Advanced Options > Command Prompt
7. Choose your PC account and enter your password to continue
8. Write the next commands (hit Enter after each line of code):

   • bootrec/repairbcd

   • bootrec/osscan

   • bootrec/repairmbr

9. Exit Command Prompt and start Windows normally

21. Disable startup programs

Your operating system might have trouble accessing files due to conflicting applications that automatically run at every Windows boot. To fix this problem, you should disable all autostart apps:

1. Press Ctrl + Shift + Esc to launch Task Manager
2. Go to the Startup section
3. Select a program with the Enabled status and click Disable. Do this for all apps with the Enabled status
4. Restart your computer

22. Run a clean system boot

You can run a clean Windows 10 boot in order to disable non-essential system services and startup items that might be affecting your applications and causing the 0xc0000005 error. Here’s what you need to do:

1. Click the Start button, search for System Configuration, and press Enter
2. Stay in the General tab
3. Choose Selective startup
4. Disable Load system services and Load startup items
5. Click Apply and exit
6. Right-click the taskbar and open Task Manager
7. Go to the Startup area
8. Disable all apps with the Enabled status
9. Reboot your PC

23. Start Windows 10 in Safe Mode

You can start Windows 10 in Safe Mode to create a secured environment for diagnosing computer issues that lead to application error 0xc0000005. Here’s what you need to do:

1. Shut down your computer and turn it on. Interrupt the boot sequence three times in a row to reach the Advanced Startup menu
2. Select Troubleshoot > Advanced options > Startup Settings
3. Click Restart and wait
4. Press F5 to boot Windows in Safe Mode with Networking or, if you don’t need Internet access to open the files or launch the applications that are giving you trouble, press F4

24. Roll back Windows 10

You can revert Windows 10 to a checkpoint that was recorded before you started experiencing the 0xc0000005 access violation error, thanks to System Restore. Before proceeding, keep in mind that all applications installed beyond the restore point will no longer exist, so you will have to reinstall them.

How to use System Restore:

1. Log in to Windows 10 using an admin account
2. Press the Win key, search for Control Panel, and open this app
3. Select Recovery
4. Click Open System Restore
5. Select a restore point from the list or click Show more restore points to inspect more options. To find out which apps you will have to reinstall, click Scan for affected programs
6. Proceed with the remaining steps. Windows will reboot to complete the restore

25. Use a Linux live distro

Unfortunately, System Restore often fails to work. When you exhaust all your options, it’s time to prepare your PC for a full reset. During preparation, you should back up all personal files and any applications you don’t want to reinstall after the reset. If you’re having a difficult time performing file operations like copying due to various errors, you can create a Linux live distro.

How to create a Linux live distro with Rufus:

1. Download a Linux distro like Ubuntu
2. Plug a pen drive into your PC. Copy any files you might need later since the drive will be formatted
3. Download Rufus from the official website
4. Set up and launch Rufus
5. Select the pen drive and set Boot section to Disk or ISO image
6. Click SELECT and add the Ubuntu ISO image
7. Set Partition scheme to MBR
8. At File system, select FAT32
9. Click OK and wait

How to boot Ubuntu from the USB flash drive:

1. Make sure the pen drive remains plugged into your computer
2. Restart Windows but, before system boot, quickly press the key displayed on the screen to access the boot startup menu (F12 on some computers)
3. Choose the USB storage drive with Ubuntu and press Enter
4. After Ubuntu loads, access your files and create a backup

26. Reset your PC

Once you make sure that all your essential files are safely copied somewhere, you can perform a factory reset on Windows 10 by removing not only applications and files, but also by formatting the drive to erase any problem that caused application error 0xc0000005 in the first place.

How to reset Windows 10:

1. Click the Start button, type Reset this PC, and press the Enter key
2. Click the Get started button
3. Select Remove everything and proceed with the next instructions

Application error 0xc0000005 can be fixed

To review, the 0xc0000005 violation error can occur when trying to open files, launch applications, or play games. It indicates an underlying problem with your hard disk or operating system that must be immediately resolved.

You can try a simple solution like restarting your computer, closing all processes, or running the app with administrator rights. However, if the problem is more complicated than that, you can run Program Compatibility Troubleshooter, clear the application cache, reinstall the program, repair and reinstall.NET Framework, check for system updates, or reset the Windows Update components.

It’s also a good idea to run the Hardware and Devices troubleshooter, fix corrupt hard disk and operating system issues, check the system RAM, update or roll back drivers, run a computer malware scan, temporarily disable the antivirus and firewall, change Data Execution Prevention settings, deactivate the LoadAppInit_DLLs registry entry, or repair the BCD file.

Furthermore, you can disable applications that automatically run at every system startup, run a clean system boot, or roll back Windows 10 to a previous checkpoint using System Restore. However, if everything fails, you can use a Linux live distro to access and back up your files in order to prepare for a Windows 10 factory reset that will surely resolve the violation error.
