Windows 10 runs many background processes for security, hardware, networking, synchronization, and installed applications. Do not stop processes simply because Task Manager shows a long list. Identify the process and the problem it is causing first.
Close a misbehaving application process
- Press Ctrl + Shift + Esc to open Task Manager.
- On the Processes tab, find the application using excessive CPU, memory, disk, or other resources.
- Save work in that application if possible.
- Select it and choose End task only when you understand what it is.
Ending a process is temporary. If the application is configured to run at startup or is managed by a service, it may return.
Reduce unnecessary startup activity
Use the Startup section of Task Manager or Windows’ startup-app settings to disable nonessential applications from launching when you sign in. This is safer than terminating unknown Windows processes every time the computer starts.
Leave Windows services alone unless you have a reason
Security, audio, networking, update, graphics, and device processes can be essential even when their names are unfamiliar. Disabling services in bulk or following an “all unnecessary processes” list can break features and reduce security.
If an unfamiliar process consumes resources, use its file location, digital publisher, and trusted security tools to investigate it. Do not assume an unfamiliar name is malware, and do not treat End task as malware removal.
Windows 10 passed the end of standard free support in October 2025. Persistent performance issues on compatible hardware should be considered alongside migration to a supported Windows version.
