Reinstall Windows Every 3 Months

Why you should, and how to do it — no fluff.

Why

Clears out background bloat, leftover telemetry apps, and driver cruft that piles up over time.
Wipes junk registry entries and orphaned services from uninstalled software.
Removes malware or adware you may not have noticed.
Frees disk space — old updates, temp files, and cache add up fast.
Resets performance back to day-one speed.
Forces you to only reinstall what you actually use, instead of years of accumulated junk.
One clean pass picks up all outstanding updates at once.

Back up your files — OneDrive, an external drive, or cloud storage. Don't skip this.
Download the Windows 11 Installation Media tool from Microsoft and create a bootable USB drive (8GB+).
Restart your PC with the USB plugged in. Press your boot menu key during startup (usually F12, Esc, or Del) and boot from the USB.
In the installer, choose Custom Install, select your main drive, delete the existing partitions, and let it format.
Follow the on-screen setup — region, account, basic preferences.
Once installed, run Windows Update and install the latest drivers for your hardware.
Reinstall only the apps you actually use.
