The 1083 error is predominantly caused when you either try and update Windows from the Microsoft website or through Windows Update. The problem is caused by certain DLL files being unregistered on your system, which prevents the Background Intelligent Transfer Service (BITS) from connecting to the update server. This problem is actually very simple to fix, by following a simple set of steps to resolve the issue that causes it.
The 1083 error normally displays like this:
Error 1083: The executable program that this service is configured to run in does not implement the service. (0x8007043B)
The best way to fix the problem is to first register the files that Windows requires when it is being updated, and then use a registry cleaner to fix all the damaged and corrupt settings that often cause further issues to the update process.
The first thing you need to do to fix the 1083 error is to use the inbuilt “regsvr32” command inside Windows to register qmgr.dll and qmgrproxy.dll. These two files are crucial for the update process inside Windows, and the good news is that if you can register them very easily by using the “command prompt” inside Windows. Load the command prompt and then let it register the various dll files that Windows requires, and it should fix the 1083 error for you.
On top of that, you should also clean out the “registry” of your PC with a registry cleaner. These are software programs which scan through your system and fix any of the damaged or corrupt settings that are inside your computer. The registry is where Windows stores all the settings and vital files that it requires to run, and unfortunately, it's also the part of your computer which is continually being saved in the wrong way, causing major problems for your system. To fix this issue, it's highly recommended that you use a ‘registry cleaner' to fix any of the errors inside the registry database… which should make your PC run much smoother and more effectively.
