Any way to transfer/copy KB4038788 to my other Win 10 system

Each update is cumulative. See post #5 for KB4038788.

I was trying not to download the latest update again. Just curious. Why make bootable drives if just getting updates? Is this needed as you are installing updates on a running/online OS? I make bootable drives for OS ISO's either with MCT or Rufus. Do not care to use MCT for a MS OS download as it is an ESD rather than a WIM file. I like WIM's because you can mount them to repair with. I now use HeiDoc to download Win 10 ISO's from MS as they(sources folder) are WIM's. MS uses ESD's which are compressed to save some bandwidth. I know there is a command prompt to look at packages(updates). Have used it once but can't remember if it also shows package size. I decided to go ahead and let my desktop PC download KB4038788. I checked my data used thru my ISP portal before the download and will recheck after to see just how much actually downloaded. I already was at version 15063.540 so only needed the portion with the latest updates.

Doing as I outlined makes it easier to get just what I want but one could go to the Microsoft Update Catalog page and search for what is wanted [997 pages at 40 items per page].
Microsoft Update Catalog

Yea, but in this case he wants a particular update, and I provided the links.

Both PC's are 64 bit. I am familiar with the variants available thru the catalog. ... I realize that they are so big because of the all the past updates. Would be nice to have the option to only download the most recent. I had been skipping one or two and then downloading the latest.

If you have skipped a few updates you have no option but to download the full cumulative update. If you follow the link to the Microsoft update catalog given in the KB article...

How to get this update
This update will be downloaded and installed automatically from Windows Update. To get the standalone package for this update, go to the Microsoft Update Catalog website.

Cumulative Update KB4038788 Windows 10 v1703 Build 15063.608

...it will show you just those updates for this particular KB (the link is a search for the relevant KB number). You will see there are Delta updates available, about half the size of the cumulative update. These should be all the changes since the last cumulative update. These can only be used if you have kept up to date with all previous updates.

Do I need to use the MCT...

The MCT has nothing to do with downloading from the Update Catalog.

I just bit the bullet last night and downloaded the latest CU thru WU. I had all previous updates so it was not a huge download. Just would like to in the future only download these CU's once for my two computers. I have both set to share updates but so far this has not worked to only get one downloaded CU for my two win 10 64 bit PC's. One is pro and one is home. Both are legit version 1703 15063.608 currently. I guess that I can just set both PC's to metered connection and then when new CU's are available just download to a flash drive as I am told a bootable drive is only needed when the next OS comes out. I will then use HeiDoc to download the new OS to get a WIM ISO version as MS uses ESD's'. I use Rufus to make my bootable usb drives. Thanks for the help. Had hoped I could use a command prompt to copy the latest CU and transfer it to the other PC. I know there are dism package info commands.

Thanks Bree! I prefer Wims as they are mountable repair options. Goes way back to a WIN 8 OEM I had that had seemingly endless WU issues and component store corruption that DISM / restore health could not fix. Way to many re-installs of the OS to fix it. MS techs couls not repair it either twice. After upgrading thru 8.1 update(S) and finally to Win 10 I used to download ISO's using MCT from MS Win 10 DL page but they were always ESD's. I understand why MS uses ESD to save bandwidth as millions use their downloads to update their OS. I just do not like a compressed image nor is it an option to mount for repair. I then used ESD to ISO script to convert. Image burn will also create ISO's. A poster here some months ago used HeiDoc and it created WIM's thru technet's site/MS servers. Been using it since to create ISO's for install and repair if needed. I have been told when Creators update installed it also replaces the RE image as well. I hope this is true but unsure how to confirm this. Thanks for all your help! Ten Forums and 8 Forums are the best!

Yes - just set settings in advanced updates and settings to allow pcs to download updates from other pcs on lan.

Update one pc first, and other will pick up updates from first pc.

It has been set that way on both PC's for 3 months thus far and no transfers. Both units are 1703 64 bit. One is home, one is pro. I do keep the second PC set as a metered connection to keep from downloading the same large CU's twice as I have a 12gb/month data cap. It also is not turned on during daytime but leave it on 24/7 each weekend to do this task. The other PC is not set as metered so it can get the updates. If MS/windows can do this automatically why cannot I do this manually. I can see the packages using dism /online /get-packageinfo command prompts. Would these packages be in temp files that windows clean-up utility shows? I clean regularly as my laptop has a 250gb ssd. I wish Ms would state updates sizes as they did in pre Win 10 so one can tell size without going to their download page to check this. I have a free-zone late at night and have been getting up in the middle of the night to download these updates. PIA. Other than that I do like 1703. Thanks!
