When using a Windows VPS, experiencing 100% CPU usage can cause slow performance, lag, or even system crashes. This article helps you understand the root causes and provides effective solutions to resolve CPU overload issues on Windows VPS.

Causes of High CPU Usage on Windows VPS

1. WmiPrvSE.exe (WMI Provider Host)
   This is part of Windows Management Instrumentation (WMI). When misbehaving, it can consume excessive CPU resources.

2. Superfetch, BITS, and Windows Search Services
   These services can drain system resources, especially on low-spec VPS.

3. Default and Background Applications
   Unnecessary default apps or background apps may use CPU without your awareness.

4. Svchost.exe Process
   A critical Windows process that, if corrupted or exploited by malware, may cause high CPU usage.
