Windows is a complex operating system, and it’s not uncommon to encounter errors from time to time. Some errors are minor and can be easily fixed, while others can be more serious and require more advanced troubleshooting.
Here are 10 of the most common Windows errors and how to fix them:
- Blue Screen of Death (BSoD): The BSoD is one of the most dreaded Windows errors. It occurs when Windows encounters a critical error and cannot recover. The BSoD will typically display a stop code and other information that can help you troubleshoot the problem.

How to fix it: There are many different causes of BSoDs, so there is no one-size-fits-all solution. However, some common troubleshooting steps include:
- Checking for hardware problems
- Updating drivers
- Running the Windows System File Checker (SFC)
- Repairing or reinstalling Windows
- Error 0x80070087: This error occurs when Windows Update is unable to install updates. It can be caused by a variety of factors, such as corrupted system files or a problem with the Windows Update service.

How to fix it: There are several ways to fix this error. You can try running the Windows Update Troubleshooter, manually installing the updates, or resetting the Windows Update service.
- Virtual Memory Too Low: This error occurs when Windows does not have enough virtual memory to run all of your open programs. It can be caused by running too many programs at the same time or by having too little physical memory (RAM).

How to fix it: To fix this error, you can increase the amount of virtual memory that Windows is allowed to use or close some of your open programs. You can also try upgrading your RAM.
- Missing DLL Files: DLL files are dynamic link libraries that contain code and data that are used by Windows programs. If a DLL file is missing or corrupted, it can cause programs to crash.

How to fix it: To fix this error, you can try reinstalling the program that is causing the error or downloading and installing the missing DLL file from a trusted source.
- Device Errors: Device errors occur when there is a problem with a hardware device or its driver. These errors can manifest in a variety of ways, such as blue screens, crashes, or unexpected behavior.
How to fix it: To fix device errors, you should first try updating the driver for the device. If that doesn’t work, you can try disabling the device or uninstalling it and then reinstalling it.
- Fatal Exception Errors: Fatal exception errors occur when a program tries to execute an invalid instruction or access a protected memory location. These errors can cause programs to crash or even cause the system to become unstable.
How to fix it: Fatal exception errors can be difficult to fix, but there are a few things you can try. First, try restarting your computer. If that doesn’t work, you can try running the program in compatibility mode or as an administrator. You can also try reinstalling the program.
- System Error Codes: System error codes are numbers that are assigned to specific Windows errors. These codes can help you troubleshoot the problem and find a solution.
How to fix it: To look up a system error code, you can visit the Microsoft support website. The website will provide you with information about the error and how to fix it.
