problem on 2018-04 cumulative update (KB4093112)

I was getting an error code: 0x80070bc2 when trying to install KB4093112. Following this step help resolved my problem just minutes ago:

• Right-click on Windows key and select Command Prompt (Admin).
• Type the following commands in Command Prompt window. To execute them, press Enter after each one. 

SC config wuauserv start= auto

SC config bits start= auto

SC config cryptsvc start= auto

SC config trustedinstaller start= auto

• Finally, restart your PC and try to install the update that was previously returning the 0x80070bc2 error.

Hi TroyKemp1,

Before this solution finlay worked, I had to  :

• Create a new (admin) microsoft account on my PC
• Restart the PC
• Login with the newly created Microsoft account
• Apply your solution with the 4 SC command
• Restard the PC again
• Relloged into the Microsoft admin account
• Finaly the update went thru
• Relloged to my local admin account
• Delete the microsoft admin account just created to apply the update.

Hope this might help other users since nothing worked for me before I decided to create a new admin account (Microsoft).  Because I coudn't create a local admin account on my PC.

Regards

Later... yes, April updates installed. Restored the VM prior to the SC commands and checked the services:

wuauserv - already auto

bits start - manual so SC command is changing this to auto

cryptsvc - already auto

trustedinstaller - manual so SC command is changing this to auto

So changing bits and trustedinstaller to auto is the fix (need to double check). Bits is a service that downloads updates from the internet (background intelligent transfer service) and has been around for ages. Trustedinstaller crops up less often and I'm going to point my finger in this direction been set to manual.

More later...

Hmm, interesting but this also worked for me. I've got a VMware virtual machine that's singularly failed to install cumulative updates for the past four months. I took a snapshot of the VM before I tried the above so I'm going to restore that image and see what state the services were in before. All the above commands are doing is changing the start-up mode of some services to automatic. This suggests that one/some of them are not in automatic start-up already. If it's that simple, Microsoft need a dressing down as it's a simple fix.

It could be though that this is coincidence because some have reported that sometimes April update finally works after several attempts.

As I write, it's not quite finished the update - about 3rd reboot with lots of much more encouraging update messages.
