Drivers

Always download drivers from the hardware manufacturer or from the company that made your device. Windows Update also provides reliable drivers.

Antivirus

Stick with Windows Defender – it’s lightweight and effective.

  • Do not turn real-time protection off. ‘Allow on device’ for false positives (e.g. Cracked software).

Alternative

Additional Resources and Notes

Avoid debloaters, heavy theming, or anything else that says it will optimise or remove telemetry from your OS. This is because it will likely cause breakage to your system that is difficult to find or revert.

It is best to use starred options in FMHY System Tools - Read the warning.
