That is why you should give it extray attention and try to solve it using any of the methods displayed below. The problem is no stranger to any version of the Windows operating system and the methods below can be applied to all of them.
Solution 1: Start the Windows Installer Service (sometimes called TrustedInstaller)
The Windows Modules Installer or TrustedInstaller service enables installation, modification, and removal of Windows components. If this service is disabled, install of Windows updates or system repair tools might fail for this PC. This service has full access to Windows Resource Protection files and registry keys and it needs to run in order for the Repair Service to run.
You may receive the following error message when you click on Start: “Windows could not start the Windows Installed Service on Local Computer. Error 1079: The account specified for this service differs from the account specified for other services running in the same process.” If this occurs, follow the instructions below to fix it.
Note: Another useful thing you can perform with the Windows Installer Service is to reregister it and check to see if that solved the problem. This will also take a minute and it can actually solve the problem. %windir%\system32\msiexec /unregserver
%windir%\system32\msiexec /regserver
Solution 2: Update Your Windows PC
Some users have reported that the problem was almost impossible to solve by any method they found on the Internet but simply installing the latest update helped them solve the problem. Keeping your PC up to date is very important and various bugs which appear on certain brands of computers are fixed with the latest ones. Windows 10 updates itself automatically from time to time and the automatic update option is enabled by default. You can also check for updates by navigating to Settings » Update & Security » Update » Check for updates. However, if you noticed that Windows is not updating regularly, follow the set of instructions below in order to fix this.

Solution 3: For Build 14279
The SFC tool is broken in this version of the Windows 10 operating system and users claimed that it didn’t work until a new version was released. However, if you are still stuck with this build of Windows and if you want to have access to SFC, you can use the workaround below in order to get it working. Preparation: You will need to take ownership of the folders below so make sure you repeat this process for the two folders you are going to take ownership of. The first one is located here: %SystemRoot%\winsxs ; and its name is amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.14279.1000_none_25a158fc7f85c69d C:\WINDOWS\servicing\TrustedInstaller.exe
Make sure you repeat the same process for the folder located in %SystemRoot%\winsxs\ with the name of amd64_microsoft-windows-servicingstack-onecore_31bf3856ad364e35_10.0.14279.1000_none_5a92ee0dd788e433 %SystemRoot%\winsxs\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.14279.1000_none_25a158fc7f85c69d
%SystemRoot%\winsxs\amd64_microsoft-windows-servicingstack-onecore_31bf3856ad364e35_10.0.14279.1000_none_5a92ee0dd788e433
Solution 4: Add a Missing Registry Key
There is a problem with certain versions of the Windows operating system where you are missing a registry key related to the ID of the TrustedInstaller service. Fixing this problem is somewhat advanced and you should follow the instructions below in order to fix it. Before proceeding with this solution, it’s recommended that you close all of your running programs and it’s advisable to create a backup of your registry just in case something goes terribly wrong while you edit it. Backup your registry by following the instructions in our article. C:\Windows\Servicing\Version
x86_microsoft-windows-servicingstack_31bf3856ad364e35_{TrustedInstaller ID} (32bit Windows) amd64_microsoft-windows-servicingstack_31bf3856ad364e35_{TrustedInstaller ID} (64bit Windows) Before you proceed, you will need to take ownership of a certain registry key which can be performed quite easily if you follow the instructions below carefully. HKLM\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing
Now it’s the time for the final part of the solution which really shouldn’t take a long time. HKLM\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing %SystemRoot%\WinSxS\x86_microsoft-windows-servicingstack_31bf3856ad364e35_{TrustedInstaller ID} (32bit Windows)
Solution 5: Running an Offline SFC Scan
This solution has only helped several people but it has helped them and the method is highly advised my Microsoft engineers and it’s quite easy to run it even if you are having issues with the SFC scan while running it normally. sfc /SCANNOW /OFFBOOTDIR=c:\ /OFFWINDIR=c:\windows
Solution 6: Rename a File
Renaming this file is helpful in many cases but it’s important that you install all pending updates on your computer before you do so because the file contains many information about the current state of your computer and the updates which are pending. Renaming it might cause these updates to not install properly.
