In the Command Prompt window run the following commands:
net stop cryptsvc
md %systemroot%\system32\catroot2.old
xcopy %systemroot%\system32\catroot2 %systemroot%\system32\catroot2.old /s
After running those commands, Delete everything in the Catroot2 folder, then run following commands:

5. Wait For the Spring Creators Update (Windows Version 1803)
If all of the above has failed to fix the problem, which is quite possible, the best solution is to wait for the up and coming Redstone 4 update (Spring Creators). This update will allow you to manually Upgrade Windows 10 to the latest version, bypassing all minor updates.
The Spring Creators was due for release on the 11th of April this year, however, has been postponed for a few weeks while several bugs are fixed. Once it has been released, you’ll be able to upgrade and fix “2018-04 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4093112) - Error 0x80070002“
How to Update to Windows 10 (Redstone) Spring Creators Manually.
Note: Step 5 isn't worth risking in my opinion, after using this method on several machines it has a 50% chance of requiring a fresh installation of Windows 10. A corruption in the update that causes Error 0x80070002 can cause the April Update (Spring Creators) to further corrupt your system, preventing all rollbacks and restore methods from working.
