How to Optimize Windows 11 for Gaming

Windows 10 is the preferred operating system in 2021.
We recommend Windows 10 Home for most people instead of Pro.
However, both versions come with unnecessary applications so be prepared to do some cleaning.
Install Windows 10 with the latest major update for maximum security, compatibility, and features for the latest games and patches.
We advise against using insider and preview builds as they are not optimized and may contain bugs.
Avoid using unlicensed versions of Window as they are prone to viruses and other vulnerabilities
Microsoft no longer maintains windows 7, and therefore it’s not recommended to use for any application in 2021.

Download the latest available release of Windows to ensure up-to-date security and the best possible DirectX support in games.

Disconnect ethernet to avoid unnecessary driver installation and registration during setup.
To create a local account during the installation, you should unplug the PC from your network.
Use a local account to limit the amount of Telemetry data that is synchronized back to Microsoft and may interfere with performance.

Avoid any bloatware installed by the OEM if you purchase a system from any of the major computer brands like Dell and HP.

Use the High-Performance Plan.
Set the highest possible setting to let the hardware draw enough power.

The most important option to set is the one to allow your CPU to run at full speed all the time.
Disable “Allow the computer to turn off this device to save power” for USB hosts and Network adapters.

Telemetry is data and information that gets sent from your PC to a server for analysis and diagnostics.
Unfortunately, this will interfere with performance and should be limited.

We are not involved in the politics of privacy, but the performance hit such tools have on our hardware.
Privacy features are usually a connected service that runs in the background.
