Feex tok say
I dey ask three things: wetin be di name, how long e don take dey busy, and PC dey really do work. Percentage wey no get name na just scare.

When busy CPU dey expected

Small spike when you open app, copy big folder, install update, or scan with Windows Security na normal work wey di machine dey do as you command am. Video, browsers with plenty tabs, and photo editors fit still high while dem dey work. Dat one na load, no be proof say malware dey.

  • Opening or installing software
  • Windows Update or Store downloads
  • Defender or other antivirus scan
  • Export, encode, or heavy browser session

Wetin to look first

Read di process name, den how long e take stay high. 20-second spike on explorer.exe after you open folder of photos different from MsMpEng.exe wey dey top for one hour while you dey idle. Open di Feex Wiki article for dat name before you change services.

Windows names wey dey often look scary

Antimalware Service Executable (MsMpEng.exe) dey scan files. Service Host (svchost.exe) fit look busy when service inside am dey work, including Windows Update. Desktop Window Manager (dwm.exe) dey draw di desktop. High use for dose names na reason to read di article, no be reason to disable di service on first try.

When e no be just spike

If di fans continue to shout, PC dey feel stuck, and di same name dey for top after you close your apps, treat am as stuck job. Check di path and publisher. Use Settings, documented troubleshooter, or di related service page. No delete System32 files or end lsass.exe and csrss.exe.
