How to fix Windows 10 Cumulative update getting stuck at 30%
Step-1: Click Start, then launch registry editor by typing regedit. When the 'regedit / Run command' displays on the top of the list, press Enter
Step-2: Inside the regedit, navigate to the following code
Windows 10
Step-3: Back up the registry key. In the ProfileList, click File, Export then choose a suitable location on your desktop and type in a file name and save
Step-4: On the left, you should see a list of profile IDs, such as S-1-5-18, S-1-5-19, S-1-5-20, including several other names
Step-5: Search for ProfilelmagePath. If any entry in the ProfileList has a ProfileImagePath that is not useful, right-click on the Profile ID and select Delete
Step-6: Close the regedit file, then reboot your system. Click Start>> Settings>> Update & Security, you should now be able to see KB3081424 and it should start installing
Hopefully, the above fix should help you overcome the installation error, allowing an error-free installation experience.
