I have the same problem. Tried 7 times up up now with no success.
2018-03 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4088776) - Error 0x80070002
I have been struggling with this issue for well over a month, It first started with the "2018-02 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4090913)". Now its update Tuesday and this months cumulative update (KB4088776) is doing the exact same thing.
I have tried all 5 of the steps provided by microsofts here: (More than once)
https://support.microsoft.com/en-ca/help/910336/windows-update-error-0x80070002-or-0x80070003
Finally, I have done a clean install of windows 10 three times now in the past couple of weeks, to no prevail.
After each fresh install. the exact same issue.
I am running Windows 10 Pro Education, Version 1709, build 16299.15.
After each install it seems to update no problem, but seems to only be an issue once I reactivate my Windows 10 Pro Activation key.
I gave up weeks ago, and was hoping my problem would simply be solved by the latest update, but that is not the case.
Any help and suggestions would be greatly appreciated.

Go to the Microsoft Update Catalog
Enter the KB number for the Update that you are experiencing problems with (make sure Avast is turned off) in your case that would be the March Cumulative Update KB4088776
Download the version that is right for your device to your desktop.
In other words click the "Download Button on the right of YOUR version.
This example is the 64 Bit version (which is what I use):
Click the blue text ending in .msu above
Now click the UP arrow next to the word "save"
and select "Save AS"
Then save it to your desktop in the usual way
When the download is finished double-click the stand alone installer (the file you just put on your desktop) and run it.
Once it is installed you can turn Avast back on.

Open an elevated CMD prompt
Using the Service Controller command, make sure these services are set to auto
SC config wuauserv start= auto
SC config bits start= auto
SC config cryptsvc start= auto
SC config trustedinstaller start= auto

2018-03-14T14:19:52+00:00 You said that you clean installed Windows 10 3 times and the issue doesn't go. So here I suggest you a working solution to this.
Reinstall Windows 10 on a new C:\ partition. During installation delete the C:\ drive and the System Reserved Partition. Now create a new C:\ partition from the entire unallocated space. Suppose your C:\ partition was 100GB and System Reserved partition was 500MB. So your new C:\ partition will be 100.5GB. Install Windows 10 on this new partition.
Here the real culprit may be the old System Reserved partition that you are using with the new Windows 10 installation.
After a fresh install everything would be fixed.
