Disable Windows Search (Temporarily or Permanently)

Why: Sometimes, Windows Search goes crazy with indexing and eats up disk resources.

To test temporarily: Open Command Prompt as Admin and run: net.exe stop "Windows Search" To disable permanently (if it's the culprit): Press Win + R → type services.msc → find Windows Search → Right-click → Properties → Set Startup type to Disabled → Click Stop

Turn off SysMain (formerly Superfetch)

Why: This service tries to "optimize performance" but ends up overloading HDDs. Press Win + R → type services.msc → find SysMain → Right-click → Properties → Set Startup type to Disabled → Click Stop

Check for Malware or Background Apps

Why: Sometimes, unnecessary apps or hidden malware keep your disk busy in the background. Press Ctrl + Shift + Esc to open Task Manager Look for processes hogging disk space Uninstall unused apps or disable them from the Startup tab
