Which services can you safely disable to improve PC gaming?
Windows has many services running in the background that waste resources better spent on games.
While PC gaming has always been an expensive hobby, hardware upgrades have become increasingly difficult investments due to various market shortages affecting GPUs and memory prices.
In the meantime, there are tricks that can stretch performance as much as possible, one being to disable unnecessary background services in Windows 11. Some services are redundant or unnecessary while actively consuming the CPU, RAM or network resources that games need.
Don't expect miracles here. Graphics are what put the heaviest burden on a gaming PC, and ultimately, a hardware upgrade is needed to see a meaningful improvement in frame rates. But nixing background services could make your setup a little smoother, regardless of what your current specs are.
The Windows services you should toggle off immediately
Somewhat ironically, one of the first features you should disable is the Xbox Game Bar. Head over to Settings > System > System components, then click on the triple-dot icon next to Game Bar and select Advanced options. Set Background component permissions to Never, then click the Terminate button to make sure it's no longer active.
While Game Bar is nominally meant to make it easier to launch games and control associated tasks like music playback and recording clips, that's unnecessary overhead for most gamers using platforms like Steam, which include their own tools.
Next, make sure Windows Search indexing is reverted to Classic by going to Settings > Privacy & security > Search. Enhanced mode has to index your entire computer, which can hurt CPU performance and battery life.
You may also want to pause OneDrive sync and other cloud tools during gaming sessions to prevent temporary CPU and network usage spikes. Right-click on the icon in your system tray and select Pause syncing.
Is there anything else worth disabling?
There's at least one more service that could be worth disabling: SysMain. Its goal is to speed up app launches by preloading items into memory, which can backfire in a gaming context. Search for Services in the taskbar, right-click on SysMain, choose Properties, and switch Startup type to Disabled.
Avoid getting overzealous; don't kill a service simply because it sounds irrelevant, as it could be responsible for critical operating system functions.
Also, don't forget to keep a lid on third-party startup apps. Go to Settings > Apps > Startup, then toggle off anything you never use or only need to run periodically.
