Windows 10 Creators Update Service Host changes

You may have noticed with the Windows 10 creators update that you have a lot more Processes running than before. This is because windows no longer groups multiple services together under 1 service host if you have more than 3.5GB of ram installed. Every service will show as a individual process. This is really not a bad thing, actually a good thing in some troubleshooting instances, security, and monitoring. 

 

Anyhow, for testing purposes I did some digging and found there is a way to re-group them. I mainly did this to compare what is running on the Creator update apposed to the previous anniversary update.

 

Here's how for all interested. 

(This should not affect anything but proceed at your own risk)

 

Open start and type regedit, right click on the icon and select run as administrator. 

 

Navigate to: HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlSet / Control

 

Locate and double click on the REG_DWORD SvcHostSplitThreshholdInKB

 

Change the value to a slightly higher amount than your installed ram in KB

 

For instance I key in 16800000 for 16GB of ram.

 

Restart

Interesting.  There are some advantages to keeping them separate, such as stability, transparency and ease of troubleshooting, and security, but for those more interested in saving RAM, good to know it can be adjusted.

Solve your own audio issues  |  First Steps with RPi 3  |  Humidity & Condensation  |  Sleep & Hibernation  |  Overclocking RAM  |  Making Backups  |  Displays  |  4K / 8K / 16K / etc.  |  Do I need 80+ Platinum?

If you can read this you're using the wrong theme.  You can change it at the bottom.

100% agree, Was just curious if it was possible so I started to dig.

Cool. Great find!

I am all for RAM is meant to be used. And I think the upsides outweighs the downsides (makes my life easier in trying to solve or even detect a svchost.exe taking 100% of a CPU core problem, and then having 20 services (or whatever) to look into.
