Microsoft has released a new patch KB428484835 for Windows 10 version 1803. This cumulative update fixes many problems such as the black screen after the update of Windows April 10, 2018 1803, but it also has some problems. Some users have reported that they have not installed this update with the appearance of error codes. And the most common of these error codes is error 0x800f0900.
How can I correct the 0x800f0900 error code in Windows 10 when installing Windows Updates Fix? Follow the steps below.
Do a Clean Boot
If Windows Update troubleshooting does not work, you can try starting your own computer and reinstalling the update. First log in as administrator and proceed as follows:
- Press Windows + R to open the Run dialog box. Then enter “msconfig” and click OK.
- Under General, select Selective start and uncheck the “Load start positions” box.
- locate the services and select Hide all Microsoft services, then click Disable All and OK.
- Choose Restart in the dialog box that appears.
After restarting the computer, you can reinstall the update to see if error 0x800f0900 is still present.
Run Windows Update troubleshooter
Let’s start with troubleshooting using the appropriate tool. Windows update troubleshooting is probably the most used tool of all the tools in the unified menu. This integrated tool should restart the update process and repair any stands. After that, you should be able to update Windows 10 to April Update by default.
Clean temporary files
You’ve probably heard about (or even tried) the go back option in the recovery menu. Namely, Windows 10 saves the installation for the previous version so that if something goes wrong, you can reset the system. It’s great on paper. However, some users suggested that cleaning these and other temporary files could correct the “0x800f0900” error.
Resetting the software distribution folder
This is a widely used method to solve all problems related to updates. Deleting the distribution folder from the software can save you days to solve the annoying problem that prevented you from updating Windows.
Fix Permission Issue
Some bugs are related to permission problems on the C : drive and can be fixed by the following steps :
- Log in to the server as “Administrator”.
- Change permissions to give the Network Services user full access to drive C.
- Log out of the server.
- Log in again as “Administrator
- Run the updates again.
This should install all future updates.
