Why Windows update installation fails: Six main reasons

Windows Update has not been successfully installed on your computer? You should know that this can be caused by a number of factors. In this section, the most common reasons why Windows updates fail.

1. Insufficient disk space

Why does Windows 10 update fail? One of the most common reasons is insufficient disk space. If the remaining free space on disk is insufficient to download and install a new version of the Windows operating system, the process stops. Unless you clear your hard drive for more free space, Windows cannot update important files and services.

In addition to the failure of Windows updates, insufficient disk space can also cause various problems. For example, when you try to copy a file/folder to the destination location, the error message " Disk space is insufficient to complete " is displayed.

2. Queue multiple updates

If you have multiple updates on your computer waiting to be installed, you should first choose to install the updates used to improve critical system components. For example, service stack updates should be installed when available. Otherwise, you will most likely find that all subsequent Windows updates fail to install.

In this case, you should restart your computer and try Windows Update again.

3. System file is corrupted

If the system files required for the operating system to function properly for some reason may be corrupted or lost, it may have a significant impact on the entire system, including failures in Windows updates. When you encounter this problem, you should perform a System File Checker (SFC) scan to clear or repair corrupt/lost system files.

4. Conflict

If any driver and hardware conflicts are detected, you may find that the Windows 10 upgrade failed.

• The system needs drivers to handle components that are not compatible with the system itself. If one or more drivers on your computer have expired (not updated for a period of time), the Windows update process may be affected.
• If one or more devices that are incompatible with the system are connected while trying to update Windows, they may interrupt the update process.

Please try to update all drivers on your computer and disconnect all unnecessary peripherals; then, try to install Windows Update again.

5. Windows Update Service Issues

If the Windows 10 update continues to fail, you should suspect that there is a problem with the update service itself. The Windows Update Service is an important component on your computer; it is responsible for automatically checking, downloading, and installing updates. If the Windows Update Service encounters problems (for example, the Update Service is not running), your Windows Update will be interrupted. You have no choice but to find other ways to download the latest Windows 10 update.
