Windows has a built-in diagnostics tool called Performance Monitor. It can review your computer’s activity in real time or through your log file. You can use its reporting feature to determine what’s causing your PC to slow down. To access Resource and Performance Monitor, open Run and type PERFMON.
Why is everything on my PC slow all of a sudden?
A slow computer is often caused by too many programs running simultaneously, taking up processing power, and reducing the PC’s performance. Virus infection, malware, hardware issue, high memory usage, etc., all could cause your computer to run slow.
How do you find out what is slowing down Windows 10?
Click the Startup tab. You’ll see a list of the programs and services that launch when you start Windows. Included on the list is each program’s name as well as its publisher, whether it’s enabled to run on startup, and its “Startup impact,” which is how much it slows down Windows 10 when the system starts up.
