How To Fix System Not Booting After KB4100347 On Windows 10

A new Windows 10 update named KB4100347 is rolling out to users and this is one of those buggy updates. It may go smoothly for some users however, if it doesn’t, your system will not boot. You will not be able to get to your desktop to uninstall or rollback the buggy update. If that’s the case, you will have to roll back the update from the Command Prompt. The trick is to find the update and to access Command Prompt without booting to your desktop. Once you have Command Prompt open though, you need to find your Windows drive, and then uninstall the update.

System Not Booting After KB4100347

Step 1: Turn on your system and boot to the troubleshooting menu. If you can’t get to the troubleshooting menu, you will need to use an installation disk for Windows to use it.

Step 2: Once you’ve booted to the Command Prompt, you need to use the Diskpart utility to move to your Windows drive. For the sake of this guide, the screenshot you see was taken on the desktop but it will be more or less the same even if you aren’t on your desktop. First, run the following command to start the Diskpart utility.

diskpart

Next, enter the following command to list all volumes on your hard drive.

list volume

This will list all the volumes on your hard drive and it’s up to you to determine which one is your Windows drive. It’s normally the C drive however, you will also see ‘Boot’ next to the Windows drive in the Info column. That’s really all you need from the Diskpart utility. Type Exit to close it.

Step 3: Type the following command and take care to replace <driveletter here> with the letter of your Windows drive.

Syntax

dism /image:<driveletter here> /get-packages

Example

Dism /Image:C:\ /Get-Packages

The command will return a list of packages. It is going to be an exceptionally long list. Look for a package with KB4100347 in the name. It will have quite a long name. Copy it by selecting it and tapping Enter.

Step 4: Remove the package with the following command.

dism /image:<driveletter here> /remove-package /PackageName:<Package name for KB4100347>

Step 5: Finally, run this command to undo any damage that has been caused.

dism /image:<driveletter here> /cleanup-image /revertpendingactions

You should now be able to boot to your desktop. If you haven’t installed this update just yet, consider skipping it and save yourself some trouble.
