How to fix Windows 10 update installation Problems
If the Windows 10 update KB5073723 gets stuck at 0% or 99% during download, or fails to install, it might be due to a problem with the file itself. The update database gets corrupted, the Internet connection is interrupted during downloading update files from the Microsoft server, any security software may block updates from being installed on your system, etc. But a corrupted Windows update cache is the most common issue, and clearing the folder where all update files are stored will force Windows Update to download fresh files.
- Cumulative updates require a certain amount of free space on your system drives to install successfully. If your device lacks the necessary disk space, the update process may fail.
- Unstable or slow Internet connections can disrupt the download and installation of updates. A reliable internet connection is crucial for a smooth update process.
- Third-party antivirus or firewall software can interfere with installing cumulative updates. Security software may block or hinder the update process, leading to failures.
- System files essential for the update process may become corrupted, preventing the successful installation of cumulative updates. Incompatibility or conflicts with third-party software or drivers on your system may prevent the update from installing.
- Errors or corruption in the Windows Registry can impact the update process. The registry is a critical database that stores settings and configurations for the operating system and installed programs.
Check Internet Connection
A stable and high-speed internet connection is crucial for downloading update files efficiently. An unstable or slow internet connection can cause incomplete downloads or installation failures.
Check and enxure connected Stable Internet connection To Download the Update files from Microsoft Server.
- Power off your router for 10-15 seconds, then restart it. Reconnect your device to establish a fresh, stable connection.
- Temporarily disconnect from the VPN to avoid interference with updates.
- Conduct a speed test to ensure the network meets update requirements.
- Use the ping command to check for packet loss and latency.
Make sure your Regional and language settings are correct. You Can Check And Correct them from Settings -> Time & Language -> Select Region & Language from the options on the left. Verify that your Country/Region is correct from the drop-down list.
Free Up Disk Space
Windows updates often require a significant amount of disk space for temporary files and installation. If your disk is nearly full, there may not be enough free space for the update files, which can cause installation failures.
Make sure that you have enough disk space to download and install the update.
You can check your disk space in Settings > System > Storage. Use the Disk Cleanup tool to free up some space by deleting temporary files, old system files, and other unnecessary data.
- To run the Disk Cleanup tool, type “disk cleanup” in the search box and select it from the list of results.
- Then, select the drive where Windows is installed and click OK. You can also click on “Clean up system files” to delete more files.
In addition, Uninstall unnecessary applications and programs. Move large files or media to an external drive to free up space. Ensure there is sufficient space for the update files to be downloaded and installed.
Disable Third-Party Antivirus
Some third-party antivirus programs may interfere with the update process because it involves modifying system files. Temporarily disabling the antivirus can eliminate potential conflicts.
Open your third-party antivirus software and temporarily disable it. Check for options such as “disable” or “turn off protection.” Also, completely uninstall the antivirus and any other security software from your system.
Perform a clean boot
Another possible cause of the update failure is an incompatible driver or software that may conflict with the update. To check this, try installing the update in a clean boot state, where only essential services and programs are running in the background.
- Type “msconfig” in the search box and select System Configuration from the list of results.
- Click the Services tab, then check the “Hide all Microsoft services” box.
- Click on Disable all to disable all the non-Microsoft services.
- Click the Startup tab, then click Open Task Manager.
- In the Task Manager window, click the Startup tab, then right-click each startup program and select Disable.
