16. Monitor your PC’s performance
Do you suspect that something might be slowing your Windows 10 PC down? If so, there are tools built into the operating system that let you monitor and analyse your PC’s performance and help identify the causes of its sluggishness.
First, right-click the taskbar and select Task Manager. Click ‘More details’ at the bottom of the window that opens, then click the Performance tab. Here you’ll see a real-time graphical representation of your CPU, Memory, Disk (hard drive) and Wi-Fi or Ethernet.
Click the thumbnails on the left to see more details in the main section on the right. If any of these graphs indicate constant high levels of activity on your hard drive, it could mean that your PC is struggling to cope with a program or process that’s running.
To find the culprit, click the Processes tab, then the column heading (CPU, Memory, Disk or Network) that corresponds to the graph showing excessive activity. For example, if the CPU graph on the Performance tab is showing high usage, click Processes, then click the CPU column until you see a small down-arrow next to the percentage figure. This will sort the list of processes so that those using the most processing power will be at the top.
Similarly, if Task Manager indicates that your memory is near to its limit, click the Memory column to find out which programs or tasks are hogging your RAM. To stop a resource-hungry program from running, right-click it and choose ‘End task’.
