A new Windows operating system just arrived and with it, a truckload of fresh tweaks that’ll help it run faster, leaner and better. It’ll take a while before we’ve collected all the good tips but for now, here’s one that might make your experience with the OS a little snappier.

With Windows, it’s always best to disable any services or processes you don’t need and the latest update is no exception. As gHacks’ Martin Brinkmann discovered, Windows 10’s Shell Experience Host can eat up abnormal amounts of CPU time and memory with not much to show for it.

Fortunately, you can make it behave with a small change. It turns out the process acts up while trying to tint your windows to match your background. If you can do without this nicety, it’s easy enough to disable:

Tap on the Windows-key, type Settings and hit enter.
Navigate to Personalization > Colors.
Turn off “Automatically pick an accent color from my background”, and select a static color instead.

As you can likely deduce, this tells Windows to use a single colour to tint the user interface, rather than constantly trying to figure out what to use dynamically. Depending on how you’ve personalised your desktop, the improvement you see from this tweak will vary.

Fix Windows Shell Experience Host process using too much memory/CPU [gHacks]


  • I’m running Windows 10 on my old Netbook (and hating it) so I was going to follow your advice but it appears Windows 10 has opted for this setting already. It must do an assessment on your hardware and decided to do everything it could to help me limp along with 1GB RAM lol.

    • Did you upgrade ? I think it picked the setting based on what you had before. At least thats what I think it did for mine, since I have 16Gb of RAM

    • It must really suck for you. Right now, I just installed Windows 10 on my Notebook and clicked on Task Manager. It turns out, the OS is using 64% of all of my RAM (Note: I have 4GB . That’s insane! When i had Windows 8, it rarely used 64% of my RAM)
      Even so, I have to admit this is waay better than Windows 8

    • I’ve got it on my netbook too, and there’s a few steps you can do that have a bigger impact if you’re on limited hardware:
      1) Disable windows defender. It helps protect the computer so this isn’t recommended unless you’re very confident or foolhardy, but it’s the biggest speed improvement you will get. You can disable it via a registry setting or local group policy.
      2) Disable start menu web search. It doesn’t affect general usage but makes it much faster for to use anything involving the start menu.

      Other than that it’s down to hardware: I upped my netbook to 2gb ram. it’s still fine at 1gb, but a bare win10 boot uses 600+mb and doesn’t give you much room to play.
      I’d also recommend an SSD if you have one spare one day. a 5400rpm netbook HDD is a bit of a bottleneck and swapping it out is guaranteed to improve performance (I’ve been tossing up whether to buy a budget 32gb SSD for $30, but that’s probably cutting it a bit too fine for me)

  • Seriously guys.. Its time to get with the program

    Ideally ANY windows operating system from Windows 7 and above, the moment you install all the updates, install the office suite etc etc you need 8GB ram to run smoothly.

    Forget 4GB of ram, you’re kidding yourself.

    Get with reality and dont listen to the minimum / recommended requirement, you should always double them if you’re living in the REAL world :).

    • Wow. I say this because I’m currently typing this on my netbook with 2GB RAM whilst having Skype, Task Manager and Groove Music (playing 320kbps) open alongside Firefox. I can happily run Office, use Dolby HTv4 and stream YouTube at the same time… It’s also really old – Atom N570, 250GB HDD. It’s also reasonably snappy.

      • OK then. How’s this.
        Intel Atom Z3735G @1.33Ghz
        1GB RAM DDR3-L
        32GB eMMC Flash
        Streaming music 320kbps MP3
        Mail app
        Clicker Heroes and Steam Client
        Task Manager
        SonicWall Mobile Connect
        Office 2013 Background
        LogMeIn Hamachi

        ++ Responds instantly 🙂 Just slightly laggy on some 3d-intensive stuff. Windows 10 Pro.

        90% RAM Usage
        60% CPU Usage

        • Its called paging.sys ram on disk/mmc 1gb real but windows can use a total of 2,7GB of ram (1gb real ddr3 ram and 1,7gb of fake disk memory) Every time your system should die out of ram windows move the data from ram to disk.

          Now my dear noob wake up…reality is cruel.

          • The ram usage of Windows isn’t that good an indicator of what it is actually using. Windows will keep various applications pre-loaded in memory based on the history of what and how often you’ve run applications in the past, with a system called SuperFetch. If the active paged memory in use is greater than what is currently available, these pre-loaded applications will be evicted from this pre-loaded cache as needed.

            The more memory you have, the more memory will be devoted to this use, to a point. This means that actively running programs should still be reasonably responsive on low memory configurations, but their initial load times will be significantly worse.

  • I spent about 16 hours digging through the system to figure out why Windows 10 was sucking down 89% – 93% of my 8 GB RAM (on idle mind you). Turns out I had driver compatibility issues stemming from HP’s poor coding and updating. I did a complete drive wipe and reinstalled Windows 10 from a disk instead of resetting or upgrading like I had originally done. Works like a charm now.

    The clean install also fixed my audio popping issues which caused any audio source to “pop” every second or so.

  • The bad video driver could result in the driver get crashed and high CPU, disk and RAM usage. So upgrading your video driver could be a probable solution to solve this issue. You could update the driver in Device Manager or by Driver Talent, which are the two easiest way to make your drivers updated. Also, you could go to manafacturer’s website to download the compatible one and install it manually.
