(via WU History)

If you can’t update it via WU for some reason (it may get stuck at 95% in some systems), you can directly download it from the WU catalog.

Direct Download Links

Update: Some users reported that they could not install the .msu file directly downloaded from the Windows Update catalog. Until MS fixes the issue, you may have to rely on the regular Windows Update to install the CU.

1. Can’t install KB3194798 update

Some users couldn’t install the update via Windows Update or by running the .msu package directly downloaded from the Windows Update catalog. The download from WU got stuck at 95% or in the early stage. And reportedly, the .msu download didn’t install for some users due to certificate issues.

2. Disk Cleanup says Windows Update Cleanup occupies 3.99 TB

Disk Cleanup showed 3.99 TB (Terabytes) as being occupied by Windows Update Cleanup files for those who could install the update successfully.

Update: The same thing happened after installing the November Cumulative Update for Windows 10 v1607 KB3200970 (14393.447).

There seems to be a bug somewhere — *perhaps* Disk Cleanup is miscalculating the size of the WinSxS folder by not considering hard links into account. What so ever, 3.99 TB still sounds enormous. The same issue has happened before when using Disk Cleanup. We’re yet to hear what Microsoft has to say about this.

Selecting the item in Disk Cleanup and clicking OK might clean up the entry, but I chose to use DISM instead. I did a component cleanup using DISM, which cleaned up some space and removed Windows Update Cleanup from the list of items to clean up in Disk Cleanup options. That’s because DISM has done the cleanup task.

Analyze and Cleanup the Component Store using DISM

Command to analyze and report if a component cleanup is required or not – to be run from elevated Command Prompt.

dism /online /Cleanup-Image /AnalyzeComponentStore

And, here is the command to do a component store cleanup.

dism /online /Cleanup-Image /StartComponentCleanup

kb3194798 3.99 tb disk cleanup

/StartComponentCleanup cleans up the superseded components and reduces the size of the component store. Note that you can’t uninstall updates after using DISM with this command-line parameter.

  1. The files on these links appear to have an invalid Digital Certificate, and thus won’t run. I get the same result from the Update Catalog. The problem only seems to affect this particular update file though, other updates download correctly.

  2. REPLYING:- Its a complete waste of time downloading this update as a standalone package as this too fails to install on W10 v1607 based machines. The fault is with the actual file & update itself it has a bug or several bugs in it.

    **Applies to this: Windows 10 v1607 x64: windows10.0-kb3194798-x64_8bc6befc7b3c51f94ae70b8d1d9a249bb4b5e108.msu [779.7 MB]

  3. My Computer after install this update have a Disk usage in 100% hapening of 15 and 15 seconds.

    I clear my computer two times to resolve this problem to see that was the update.

    I’m very nervous with this.
