We have all experienced it—sitting and staring at a slow PC and wondering why it has the pace of molasses. Although Windows 11 has a lot of features, recent performance benchmarks of Windows 11 posted in 2026 indicate that background bloat continues to consume a lot of RAM. Disabling unnecessary services could trim the fat off your system but would do so without compromising the essentials that you actually use.
Turn Off Fax Services

You are unlikely to require the fax service running unless you are in 1995. This is a memory-saving tip, which disables this, saving a small chunk of memory and removing an unwanted background listener.
Disable Xbox Game Save

Provided you are a pure business user who has never gamed, then this service is dead weight. According to research, the background telemetry can be reduced by disabling cloud-syncing services of the applications that you do not own.
Pause Remote Registry Access

This service enables remote users to alter the settings of your system, which may be a security risk. To most home users, leaving this disabled may help to lock your PC against illegal alterations.
Disable Bluetooth Support Service

In case your desktop PC does not have a Bluetooth chip or you just have wired peripherals, this is safe to cut. It prevents the system from polling all the time in search of devices that are nonexistent devices.
Never Disable Windows Search

Switching this off may corrupt your Start Menu and cause you to take a while to find files. Studies on file system indexing indicate that the convenience offered by the performance cost is generally well-esteemed.
Keep Windows Update Active

A big security gamble is turning off updates, leaving your system at risk. The 2026 roadmap of Microsoft underlines that only by being up-to-date can one get essential patches against new exploits.
Maintain Your Windows Firewall

The service is your initial defense against attacks by networks. Security gurus will often caution that by turning off the native firewall, you will be putting your personal information on the wrong side of a vicious scan.
Leave Plug and Play Running

This is the “magic” that makes your USB drives and printers work instantly. Switching it off would have you manually setting up each device, which is an enormous nightmare for users.
Keep DCOM Process Launcher

This fundamental service is critical to numerous Windows applications interacting with one another. When you switch this off, your system may not boot or crash regularly when it is in use.
Preserve Remote Procedure Call

This is often referred to as RPC and is arguably the most important service in the whole of the OS. One sure way of bricking your Windows installation is by disabling it, which will cause a full system repair.
Keep User Profile Service

It controls your login details and personal settings each time you boot up your PC. In its absence, you would, in effect, be locked out of your own computer and the files that you had saved.
