Microsoft Windows 10 Build 14942 Increases RAM Usage

Microsoft pushed out its Windows 10 Build 14942 to Windows Insiders today. Although the latest build contains several improvements, it will result in higher RAM usage for most users.

The End Of Svchost

Microsoft started to use grouped service host processes (svchost.exe) with the introduction of Windows 2000 as a method to conserve available memory. Microsoft continues to use svchosts today, but it isn't as necessary because the amount of RAM in typical computers has significantly increased.

A key feature of Build 14942 is the end of svchosts on systems that have more than 3.5GB of RAM installed. Instead, each service will run as a separate process. Microsoft said that this would increase service reliability, and it will increase transparency because you'll be able to see which services are running. It will also increase RAM usage somewhat, however, which could have a negative impact on devices with only 4GB of memory.

Smaller Changes

Although the end of svchost is the most important change in Build 14942, Microsoft made numerous smaller changes to Windows 10 in this build, as well. Microsoft added the option to hide the app list in the Start menu, which the company noted was a highly requested change. Microsoft added this option to the Settings panel in Build 14942, and now you can hide the app list.

Microsoft also updated the Photos app with a new, more polished design. Microsoft will also push the Photos app to the Xbox One soon. The build contains a useful modification to the Active Hours setting for businesses, which will allow companies to set up to 18 hours as active usage times. The system will not attempt to update during this time so as not to disturb your work.

In Scan Mode, there are a series of new commands to help you navigate and edit documents faster and easier.

    Finally a use for my 32GB RAM.

    Was there an issue with service reliability to begin with? I've used win2k, winxp pro, vista (briefly) and win7 but can't recall any major issues. I'm just curious what all these issues are they set out to fix.

    Yeah, google svchost high cpu usage and watch the carnage. I've experienced a couple of them on Win 7 machines. Windows update maxing a core 24/7 while it ran it circles. Audio driver that wouldn't quit gracefully after alt-f4 out of games. Netsvcs too. I think is more of a sandboxing thing, like when Chrome first started running Flash instances as separate processes.

    You may be the only one cheering for increased RAM usage in an OS. Android user? ;)

    This won't impact many desktops, and I'll certainly be happy to see exactly what process each svchost was handling. However, this could negatively impact Win10 tablets as many only have 4GB RAM.
