Windows 10 Cumulative Update KB3194798 on 10/11/2016 shown as 3.99 TB size in Disk Cleanup

Yesterday I installed the KB3194798 Cumulative Update for Windows 10 1607 build on 2 Desktops and 1 laptop.  They were all successful but took quite a while to download and install on each.  When I confirmed that everything was working fine, I decided to run Disk Cleanup as an administrator and on all 3 computers, Disk Cleanup listed the size of the Windows Update files that could be deleted as 3.99 TB, yes terabytes!  What was shocking was the fact that I only have a 250 GB SSD drive on my laptop, one PC has a 256 GB SSD main drive and a 2 TB secondary, and the third has a 500 GB SSD with a 2 TB secondary drive.  Plus, the cleanup should only be referring to the main drives which were all less than 1 TB. The cleanup process took 20 minutes or longer on each computer.

So, how can Disk Cleanup list the Windows Update file size as 3.99 terabytes on all 3 computers?

The same here, most probably a glitch in the system, I just deleted, no problem - will report via Feedback Hub.

None of my drives indicated they were full or abnormal!!!!

       
A computer is a device, that requires human input to operate efficiently.
Alas we humans do fail!!!!

Thanks for the quick response Shilohbob.  All 3 of my computers that I noticed the impossible size of the data are working fine.  I agree it is just another glitch in the series of glitches that Microsoft has provided us with.  I have 2 more computers that I will be updating at my second home in 2 weeks and I will be willing to bet that I will see the same thing on those as well.

Just something I brought up since I thought it was interesting.

I'm in the process of installing the KB3194798 to my Windows 10 1607 build desktop, and I've not yet ran Disk Cleanup since the initial 1607 (Anniversary) upgrade was installed, so thank you for reminding me to do so.

I've had a previous update (1607) hang in mid installation. You stated the update took quite awhile, so should I be concerned that the KB3194798 update has been at 88% for over 50 minutes now?

Thanks again for reminding to run Disk Cleanup, and for any other help you may offer.

Sherri,

I have had that happen in the past as well.  It could be the amount of traffic in your area if you are on a DSL connection like I am or the amount of traffic at the server.  It usually finally completes the download but all 3 of the computers that I have installed that update on took almost an hour for me on my rural Wyoming DSL connection.  Hope yours is done by the time you read this.

Opening up an admin prompt and pasting this in: Dism.exe /Online /Cleanup-Image /AnalyzeComponentStore will get rid of it faster than Windows Update Cleanup(at least it did for me

Thank you Clifford.  Your method is way above my knowledge level but I will save the info for the next major Windows 10 version update since Disk Cleanup took around 20 minutes to delete the Windows Update files on each of my computers.

It took just over 2 hours for the KB3194798 to install on my Windows 10 1607 build desktop. I have Comcast Broadband, and I started downloading/installing the update around 5:00 am and it finished just shy of 7:00 am.

I think I may have an issue with my rented Comcast Arris TG862 telephone/modem/router I'm going to be trading it on a new one when I return some equipment. The Comcast router has been acting up since I hooked it up to this new Windows 10 desktop. The router worked perfectly fine on my Windows7 Pro desktop and laptop.

I shared this just incase someone with the same modem was having speed/connectivity issues.

Thank again for your help! Best Regards ~ Sherri
