Microsoft has released a new hotfix KB428484835 for Windows 10, version 1803. This cumulative update fixes many issues, such as the black screen after Windows 10 April 2018 Update 1803, but it also has issues. Some users reported that they did not install this update due to error codes. The most common of these error codes is error 0x800f0900.
How can I fix error code 0x800f0900 on Windows 10 while installing Windows Update Patch? Follow the instructions below.
Perform a Clean Boot
If the Windows Update troubleshooter doesn’t work, you can try starting your own computer and reinstalling the update. First, log in as an administrator and do the following:
- Press Windows + R to open the Run dialog box. Then enter “msconfig” and click “OK”.
- In the General section, select the Selective Startup checkbox and uncheck the Load Start Positions checkbox.
- Find services and select Hide all Microsoft services. Then click Disable All and OK.
- In the dialog box that appears, select Restart.
- After restarting your computer, you can reinstall the update to check if error 0x800f0900 is still there.
Run Windows Update Troubleshooter
Let’s start troubleshooting with the related tool. Troubleshooting Windows Updates is probably the most widely used tool of all One Menu Tools. This built-in tool should restart the update process and restore all media. You will then be able to update Windows 10 to the April default update.

Clear Temporary Files
You’ve probably heard (or even tried) the “Back” option in the recovery menu. Windows 10 retains the installation of the previous version, so you can restart your system if something goes wrong. It’s great on paper. However, some users believe that clearing these and other temporary files can fix the “0x800f0900” error.
Reset SoftwareDistribution Folder
This is a widely used method to resolve all upgrade issues. Removing the Software Distribution Folder can save you days to fix an annoying issue that was preventing you from updating Windows.
Solve Authorization Problem
Some errors are related to permissions problems on the C: drive and can be resolved with the following steps:
- Log in to the server as “Administrator”.
- Change the permissions to give the network service user full access to the C drive.
- Disconnect from the server.
- Log in again as “administrator”
- Run updates again.
- This should install all future updates.
