Windows 10 update KB3200970 stuck
Thursday, November 10. 2016
Hands down KB3200970 is the worst update I've seen for Windows 10!
In general I hate Windows 10 TiWorker-process. It sucks CPU like there is no tomorrow. I cannot comprehend how difficult it is to determine if an update is needed or not. If you compare to any Linux .deb or .rpm packaging, a simple update check in Windows 10 is way too heavy. I find this kind weird. When Microsoft announced simplifying servicing models for Windows 7 and Windows 8.1, the reasons were to reduce scan times and finding right patches easier. It certainly doesn't feel like it to me.
So, there is Cumulative update for Windows 10 Version 1607 and Windows Server 2016, released November 8, 2016. This is also known as KB3200970 and boy, do people have trouble installing it!
This is what happened to me:
For about 8 hours it was stuck there in the preparing phase. While doing absolutely nothing, this was my CPU-load:
Well done idiots! 
Net is full of stories like mine: How to fix Windows Update in Windows 10 if it becomes stuck, Windows 10 KB3200970 issues: install fails, high CPU usage, battery drain and more and Cumulative Update for Windows 10 Version 1607 for x64-based Systems(KB3200970).
The Reddit-article had a link to KB971058, How do I reset Windows Update components? which helped some. I gave it a try and it did help.
First some services needed stopping. This is what you would run as an administrator cmd.exe:
net stop bits
net stop wuauserv
net stop appidsvc
net stop cryptsvc
In my case the wuauserv didn't stop, I had to find the process id for it and kill it manually. After all that, I attempted renaming:
Ren %systemroot%\SoftwareDistribution SoftwareDistribution.bak
Ren %systemroot%\system32\catroot2 catroot2.bak
First one failed, so I don't know what the impact was. Then I ran the entire list:
cd /d %windir%\system32
regsvr32.exe atl.dll
regsvr32.exe urlmon.dll
regsvr32.exe mshtml.dll
regsvr32.exe shdocvw.dll
regsvr32.exe browseui.dll
regsvr32.exe jscript.dll
regsvr32.exe vbscript.dll
regsvr32.exe scrrun.dll
regsvr32.exe msxml.dll
regsvr32.exe msxml3.dll
regsvr32.exe msxml6.dll
regsvr32.exe actxprxy.dll
regsvr32.exe softpub.dll
regsvr32.exe wintrust.dll
regsvr32.exe dssenh.dll
regsvr32.exe rsaenh.dll
regsvr32.exe gpkcsp.dll
regsvr32.exe sccbase.dll
regsvr32.exe slbcsp.dll
regsvr32.exe cryptdlg.dll
regsvr32.exe oleaut32.dll
regsvr32.exe ole32.dll
regsvr32.exe shell32.dll
regsvr32.exe initpki.dll
regsvr32.exe wuapi.dll
regsvr32.exe wuaueng.dll
regsvr32.exe wuaueng1.dll
regsvr32.exe wucltui.dll
regsvr32.exe wups.dll
regsvr32.exe wups2.dll
regsvr32.exe wuweb.dll
regsvr32.exe qmgr.dll
regsvr32.exe qmgrprxy.dll
regsvr32.exe wucltux.dll
regsvr32.exe muweb.dll
regsvr32.exe wuwebv.dll
Lot of them failed, but that's what the KB971058 told to do. Then starting the services:
net start bits
net start wuauserv
net start appidsvc
net start cryptsvc
Still this update tested my patience. It ran couple hours preparing after it announced, it's ready to go install. The installation took yet another couple hours. After the installation was completed and the obligatory reboot was done, Windows still reported that a reboot is required. This update really sucks ass!
Ultimately my laptop spent more than 50 hours to install all this. There were number of retrys and times than I didn't care to look to closely what's going on, so the machine had to wait for user interaction. Still the process was paintakingly long.

Looks like this is still relevant today with every Cumulative Update that comes out, especially on Windows Server 2016. Feel free to use Sysinternal's Procmon to find out, that tiworker.exe is hammering the registry searching for non-existent keys. It looks like a developer fault, scanning for almost 10000 iterations of one registry key (almost none of them are -what a surprise- NOT FOUND). But of course, nobody at Microsoft would ever fix this...it's easier to have 10000 people from india, dealing with 10000 annoyed customers in Forums nobody from M$ will ever visit or read in...Comment (1)
