    Hello Dick, :)

    SvcHostSplitThresholdInKB DWORD is used to reduce the amount svcshost.exe processes by increasing the threshold for when the service processes split.

    The default and recommended behavior is having more svcshost.exe processes by leaving the SvcHostSplitThresholdInKB DWORD set to 380000 for the reasons at the top of the tutorial.
    That makes sense, and is clear now. It's the reverse of what it looks like on the surface. Threshold was the keyword there. Guess you could turn it off completely by using the 64GB value, but why on earth do that! :)

    Thanks, Shawn!

    I think that the real question was, why to do this?

    Well, people thinks they will reduce memory consumption is they leave the old service model. The truth is, that is an illussion, I tried this tweak, and in fact, in my 16 GB system, it reduces RAM usage at boot from 1.4 GB to 1.3 GB (my normal in 1607 build), but as time passes, the RAM usage is being the same as leaving the threshold by default.

    Honestly, I woudn't fret this so much if you have more than 4 GB, this won't make any difference, but instead, as I noticed, can make this particular version of windows boot slower. Remember Windows knows how to manage RAM, more in this editions, you won't be run out of memory unless you have 20000000+ programs open.

    Still, for the memory freaks, this is a good tutorial, thanks @Brink!

    Shawn explained it very well in the OP as to why to do it.

    Always nice to have more settings to play with just for the sake of it.

    It's already been explained in depth as to the why. It is not a memory tweaking issue, it is a performance/stability issue.

    I guess it will now be easier to spot if a service is causing problems or not. I mean, being like this, I feel this windows more stable than 1607... dunno if it's just my personal perception.
