If you are running Windows Update on your Windows 10 computer and you suddenly encounter error code 0x8000FFFF, E_UNEXPECTED – Unexpected failure then read on as this post will give you a couple of suggestions to resolve this problem. Note that you can encounter this error not only on Windows Update but also on Microsoft Store apps at times.
Follow the options given below to fix error code 0x8000FFFF, E_UNEXPECTED – Unexpected failure error on your Windows 10 PC.
Option 1 – Try to reset the Microsoft Store cache
Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.
- Right-click on the start button and click on Command Prompt (administrator).
- Next, type in the command, “wsreset.exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
- Now restart your PC and afterward, try opening Microsoft Store again.
Option 2 – Check the Cryptographic Service
- Tap the Win + R keys to open the Run dialog box.
- Next, type “services.msc” in the field and hit Enter or click OK to open Services.
- From the list of Services, look for the Cryptographic Service. Then right-click on it and select Properties from the context menu.
- After that, check if the service is started by checking the Service status. If it is started, click on the Stop button to stop the service and if it is already stopped, leave it as it is, at least for now.
- Next, make sure that the Startup type menu in the Service’s properties is set to Automatic before you go on.
- Now confirm any dialog boxes that may appear as you set the Startup type and then click on the Start button located in the middle before you exit Properties.
Option 3 – Delete the contents in the Software Distribution folder and Catroot2 folder
- Open the WinX Menu.
- From there, open Command Prompt as admin.
- Then type in the following command – don’t forget to hit Enter right after typing each one of them.
net stop wuauserv
net start cryptSvc
net start bits
net start msiserver
- After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
- Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:
- Type each one of the following commands.
net start wuauserv
net start cryptSvc
net start bits
net start msiserver
- After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.
Option 4 – Check the Root Permissions
You might also want to check the permissions on the root of C: and make sure that “BUILTINUsers have read access because if it doesn’t, then no wonder why you’re getting the error code 0x8000FFFF.
Option 5 – Try to use the Media Creation tool
The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.
- After making the bootable drive, you need to plug it into your computer and then reboot.
- Next, tap the F10 or Esc key to open the boot options.
- Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.
Option 6 – Try installing the updates in a Clean Boot State
It could be that some third-party application is the one that’s causing the problem so it’s best if you put your computer in a Clean Boot state. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.
- Log onto your PC as an administrator.
- Type in MSConfig in the Start Search to open the System Configuration utility.
- From there, go to the General tab and click “Selective startup”.
- Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
- Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
- Click Disable all.
- Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
- After that, try to install the Windows app again.
Note: If you are able to install the app without any trouble at all then it means that the error is caused by some third-party application in your computer. You need to look for the culprit and uninstall it once you found it.
Option 7 – Run the Windows Update Troubleshooter
Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like error code 0x8000FFFF. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.
