Why Is Your Windows 11 Running Slow?
Before diving into the fix, it helps to understand what might be slowing down your system. Common culprits include:

- Low disk space – A nearly full SSD or HDD can slow everything down.
- Background processes – Unnecessary apps eating up RAM and CPU.
- Malware or viruses – Hidden infections can drastically reduce speed.
Luckily, Microsoft provides a built-in troubleshooter designed to detect and fix many of these issues automatically.
