How to fix error 800f0902 when updating Windows?

800f0902 is a fairly common update error that appears on Windows 7, Windows 8, Windows 8.1 and Windows 10. However, on the last three OS versions from Microsoft, the error code looks slightly different, for example, 0x800f0902 or 0xc800f0902.

In most cases, error 800f0902 occurs because the Trusted Installer service is busy processing multiple requests from another client. Given that the Trusted Installer interacts with critical system files, its work cannot be interrupted by normal methods.

Typically, error 800f0902 occurs when checking for new updates or after automatically installing them, which, of course, ends in failure. Often, this problem is complained about by PC owners who have not installed new updates for their Windows for a long time.


If the 800f0902 error is caused by a downloaded Trusted Installer, then waiting is a perfectly reasonable solution. However, in some cases, corrupted installation / temporary update files may be the cause of this error. In this case, the user may be required to clear the Software Distribution folder.

Error 800f0902 can also appear when Windows, for some inexplicable reason, tries to install updates that are already present on the system. In addition, you should not exclude the possibility that the error occurred due to the fault of a problem located on the side of the servers directly from Microsoft itself.

The note: Before we move on to the methods, you need to make sure that your PC has a stable Internet connection. Also, do not forget that an activated proxy server and VPN can interfere with a normal Windows update.

Method # 1 Launching the Internet Explorer browser

Error 800f0902 may be related to incomplete initialization of Internet Explorer. Some users managed to get rid of the error by running Internet Explorer on their computer. Even if you are using a third-party browser, such as Google Chrome or Mozilla Firefox, try opening Internet Explorer, wait a minute or two, and close the browser.

After such a simple operation, go to your Windows Update and start the update process again.

The note: this method will only be useful if you are not Internet Explorer or completely open it on your system. The latter is quite difficult to do, but some users still manage to do it, for example, by borrowing a third-party browser installer from another computer.

Method # 2 Restarting the module installer service (TrustedIstaller)

TrustedInstaller.exe is the executable file for the Windows Modules Installer service. What does this service do? Actually, she is responsible for installing, removing and even changing various update modules and Windows hotfixes. Sometimes TrustedInstaller.exe takes an insane amount of system resources to work – this can cause problems during the installation of updates for the OS, including error 800f0902.


You need to restart the Modules Installer service and see if that fixes the Windows update issues. To restart this service, you need to do the following:

  • Press the combination Win + R to bring up the “Run” window.
  • Insert the value “services.msc” into a blank line and press ENTER.
  • Click the service “Windows Modules Installer” in the list and double-click on it with LMB.
  • Click on the “Stop” button, then – “Start”.
  • Save changes by clicking “Apply” and “OK”.

Great, the Modules Installer service has been restarted – it’s time to start a system update. If no 800f0902 error occurred, then the problem was just a hung TrustedIstaller service.

Method # 3 Scanning for corrupted system files and recovering them

Damaged system files can cause error 80080005 to appear. This situation usually occurs after a sudden interruption in the installation of one of the Windows updates. However, other, more confusing reasons are not excluded, but today is not about that. One way or another, it is possible to restore damaged system files using the System File Checker (SFC) utility.


To start up the SFC utility, you need to do the following:

  • Press Win + R on your keyboard to open the Run window.
  • Write in an empty line “cmd” and press CTRL + SHIFT + ENTER.
  • Calling the Command line in front of you with the rights of an administrator account, insert the command “sfc / scannow” into the console and press ENTER.
  • Wait for the end of the scan and see the results.
  • Reboot your PC.

Go to the Update Center and check if the error 80080005 has disappeared. If the SFCs were damaged, then the error will almost certainly no longer pester you.

Method # 4 Resetting the Software Distribution folder

The Software Distribution folder contains the installation / temporary files for the Update Center. The user does not need to interact with this folder, but if there are problems with updating the system, you may need to reset it. Resetting Software Distribution means simply renaming a folder – nothing more.

  • Press Win + R on your keyboard to open the Run window.
  • Write in an empty line “cmd” and press CTRL + SHIFT + ENTER.
  • Now run the following series of commands in the console:
    • net stop wuauserv
    • net stop cryptSvc
    • net stop bits
    • net stop msiserver
    • ren C: Windows SoftwareDistribution SoftwareDistribution.oldren C: Windows System32 catroot2 Catroot2.old
    • net start wuauserv
    • net start cryptSvc
    • net start bits
    • net start msiserver
  • Close Command Prompt and restart your computer.

After renaming the Software Distribution folder, the problems with updating Windows in the face of error 80080005 should disappear.
