We couldn't finish installing updates (KB4074588), error 0x80070bc2

Whay about when your system goes into an endless loop of 'We couldn't complete the changes', 'getting windows ready ', restart.  How do I get the system out of this endless garbage.

Whay about when your system goes into an endless loop of 'We couldn't complete the changes', 'getting windows ready ', restart.  How do I get the system out of this endless garbage. 

the way I got around that is to set the active hours 10 to 2 am and restart on Sundays only. So when I start on Sunday morning, it is a restart as well. So it does the cycle and a raises the 'restart' flag but it can not restart again  because it is after 10 am. It waits till next week.  

This issue has been going on for a long while, I wonder If Microsoft is working on a solution. I mean, If they acknowledge that there is an issue and they are working on it, I am happy to wait and work around. If this is not resolved soon, it is time for me to upgrade my notebook soon, So, I may have to  start looking for other Operating system.

Same problem here with awaiting restart for KB4074588, but none of the fixes were working until I uninstalled Office Basic 2007 (along with the Office updates and service packs). 

After that I was able to uninstall KB4074588 (after many reboots).

Paused Windows updates and told it to uninstall KB4074588 and KB4074595 (Adobe security installed the same day as 4074588) and rebooted. On startup it was "Setting up updates". Started at about 12 stages.

The two KBs were still listed in Uninstall an update so I would "uninstall" them again and reboot. On startup it was "Setting up updates" with one less stage. Kept doing this until 2 stages left when it finally completed and the two KBs were no longer listed in Uninstall an update. 

Un-Paused updates and it added  KB4090913, KB4090914 and KB4087256 to installed updates. 

KB4074588 is now listed as Failed in Update History with the code 0x80070643 and not listed in Uninstall an update. 

Tried manual install of KB4074588, but it spit out "the update is not applicable to your computer". 

The OS Build is now 16299.251 (started out at 16299.192), so it should be installed. 

KB4090913 is also listed as Failed in Update History (error code 0x8024000b), but is listed in Uninstall an update. 

Reinstalled Office 2007 and let it update. 

So far (a few hours later) no problems. 

Thank you, but frankly, I'm not about to go thru all of that to "fix" Microsoft's failures.  The updates will continue to not "complete" until they fix it.

hear, hear. if it is not fixed soon, I will have to go to opposion, namely Apple.

If you are currently experiencing the 0x80070bc2 error while attempting to install KB4074588, please try this:

1. In the search box on the taskbar, type cmd.
2. Right-click Command Prompt in the search results and select Run as administrator.  (Select Yes, when prompted by the User Account Control.)
3. In the Administrator: Command Prompt window, type the following command and press Enter:

SC config trustedinstaller start=auto 4. Restart the PC.

In some cases, a second restart may be required. If you look under Settings > Update & security and you see the message Status: Awaiting restart, restart the PC a second time to complete the installation.

Paul...

FINALLY!!! After at least 7 different suggestions found on the Internet and from this forum a suggested solution that worked!! Thank you, Paul, you are the only one that actually could solve this issue. It took a long time for the computer (a Dell Desktop 8920) to complete this process, and I have an extremely fast Internet connection, but the wait was well worth it. My computer is now updated to latest build16299.251 and no updates are showing failed or "restart" messages to install! Yipee...
