Same image, different install sizes...

I have a i7-13700k/Z790 and a i7-7700k/Z270 and I used the old one to test my unattended image, and then I install that same config on the new one, changing only the name of the computer and the drivers folders, everything else should be the same. I use the exact same preset in NTLite.
Surprisingly, install size on C:\ is around 36Go on the 128Gb Sata SSD on 7700k and only 20Go on the 512Gb Nvme SSD on 13700k, both having 16Go DDR4 ... That's 16Go difference between the two deployments !
Can anyone explain that weirdness to me ?
 
May be related to one or both of these other posts. Inside both threads you'll find all the responses that everyone will also reply to this new thread here, so you may as well read through the links and see if that information applies to your situation. If not, then wait and see if Nuhi can look into them further, now that another user is reporting it too:

Thanks for your reply, I've read thoses post before posting mine.
One of the other post seems not related since it deals about Image size and not Installation size and the other one didn't helped me.
 
1. Check the actual disk space used by Windows:
DISM.exe /Online /Cleanup-Image /AnalyzeComponentStore
Click to expand...
1 (a). Check the size of Driver Store:
powershell -nop -ep bypass - C "\"{0:N2} GB\" -f ((gci –force $Env:windir\System32\DriverStore\FileRepository –Recurse -ErrorAction SilentlyContinue | measure Length -s).sum / 1Gb)"
Click to expand...

2. Check the size of hibernation file (if enabled):
dir c:\hiberfil.sys /ah
Click to expand...

3. Check the size of Reserved Storage (if enabled):
fsutil storagereserve query C:
Click to expand...
 
Hello, and thanks for your good help !

Less than 0.3 GB difference with <DISM.exe /Online /Cleanup-Image /AnalyzeComponentStore>
From 2.28 GB to 19.90GB discrepancy with <"{0:N2} GB" -f ((gci –force $Env:windir\System32\DriverStore\FileRepository –Recurse -ErrorAction SilentlyContinue| measure Length -s).sum / 1Gb)> !!!!
Hibernation and Reserved Storage Disabled.

You found the culprit ... any hints on thoses 20 GB of drivers ?
Motherboard is Asrock z270 Taichi while new one is Asrock z790 Pro RS/D4.
Driver folder size for z270 is 1.15 Go and for z790 it is 380 Mo, both without nVidia ... nowhere near those 20 Go, hard to understand how and from what another 19 Go or even 2 Go gets created.
 
powershell -nop -ep bypass -C "gci -force $Env:windir\System32\DriverStore\FileRepository -ErrorAction SilentlyContinue |% { '{0,9} {1}' -f (gci -force -r $_.FullName | Measure-Object -Property Length -sum).Sum,$_ } | Sort-Object -Descending | select -First 10"
Click to expand...
Change the "select -First" to list the top [N] folders.

Nailed it !! Another user saved ... ;)

I checked with your last tip, and i got a great bunch of hdx*.inf, -First 50 still over 200Mo ...
Desinstalled realtek audio drivers, and overall space used on C:\ came down from 36 Go to 16 Go, amazing !!
Driverstore returns 2.5 GB now.
Installed same audio drivers as Z790 (I was expected them not to be compatible) and everything works great now.
Old deployment is even smaller (4Go) than new one, but it is not enough to bother me.

Great many thanks garlin, and hope this will help people to save 20 Go !
 
I hate to ask but what is "Go"?? The only thing that turned up is a M$ product. Is that some other way of writing GB?
 
OP is from a country with language police. Disque dur is measured in gigaoctets (Go).
 
French & French Canadian authorities ban using the preferred English terms like "disk drive", Gigabyte.
If you carefully read Seagate or WD packaging, it's printed that way.
 
I just discovered that those 20 Go, GB or Gb is roughly the difference between HDA and UAD type of Realtek drivers (!!!)
 
Just to add - on a final install after WU update drivers, it can reduce the installation quite a bit by removing old drivers, what Windows doesn't delete using RAPR (run as admin).
Just rightclick and select all and Delete Driver (Don't use Force deletion as WU will download all installed/ used drivers again).
Works fine removing a gig or so with outdated display drivers like Nvidia/ AMD.
 
Or just nuke Windows Update ...
I mean if you are the type to deploy your own image, two maybe three up to date installs per year is more than enough to feel secure while avoiding brand new bugs along with brand new updates.
