2018-03 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4088776) - Error 0x80070002

You can stop it by doing some steps. I made a video for you if you see this then can be able to stop this in your laptop. How to Stop Windows Ten From Automatically Downloading & Installing Updates!

So my route was not to reinstall windows.

I removed Malwarebytes and every other programme that could cause of the problem, including Avast. I left Defender running.

Additionally, I did a clean boot as well as restart into safe mode to perform the following; remove windows updates with the incorrect installation date, then go back to the closest restore point. I think I had turned to manually windows update in services or had it on delayed automatic. If you don't have incorrect installation dates such as mine it might be make sense to remove the last update as the solution for me was via that it started installing updates as part of the system restore process - which I hadn't expected and was surprised to find worked.

NB I have just seen that both strategies are suggested by m/s and others - conflict with intrusive software, and use 'restore point' process to clear the error.

As a last resort I had planned to switch off windows auto-updates permanently to avoid the cumulative failures you have experienced as this slows everything.

I have the exact same problem. Reinstalling Windows 10 does not fix it.

My computer restarts twice each time a boot up.

I have had 19 failed attempts with the error :

2018-03 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4089848) - Error 0x80070020

I am awaiting Microsoft to fix the issue. with an update or something...?

I have managed to fix this on my laptop. I selected the most recent restore point and crossed my fingers. During the restore process it started to download and install updates so bringing windows bang up-to-date. 

As I have spent the last four days working on this I'm relieved!

I resolved the problem with Edge by changing the settings in Trusteer Rapport, Early Browser protection setting should be 'never'. (Thank you for this - Yaniv at IBM!)

During the restore process I got an error due to running Avast, so I had to do it again without Avast (removed completely) but defender still on.

I tried manually installing the updates - I've done this before successfully - but this time they saved with an install date of 01/01/1601 (year zero). I'm no techie but my guess is that if you have manually installed updates before this is the cause of present failures?

When I now look at update history it tells me that KB4088776 has installed 4 times successfully - fine be me!

I deleted the updates that had the wrong install date showing, and performed as much as possible in safe mode with minimal services running via config sys to reduce any possible conflicts.

I had a few moments when I thought that restore had crashed the machine (e.g. black SOD) - I simply did a hard shut down and then powered up - restore sprung back into life.

I tried a number of restore and repair procedures before doing all of this - nothing flagged up. Very useful tool is ResetWUEng. Thank you to the genius for that!

Good Luck!
