If your PC isn't responding well or doing things as quickly as you think it should, you can try some of the tools included with Windows to help improve performance.
The tasks in the left pane of Performance Information and Tools can help you improve your PC's performance.
Open Performance Information and Tools by swiping in from the right edge of the screen, tapping Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Search), entering Performance Information and Tools in the search box, tapping or clicking Settings, and then tapping or clicking Performance Information and Tools.
Adjust visual effects
Some visual effects can slow down other tasks on your PC. You can turn these effects on and off and view more options.
Adjust indexing options
If it's taking too long to search for things on your PC, you can narrow your search to focus on the files and folders that you most commonly use. For more information, see Indexing and Search: Frequently asked questions.
Adjust power settings
Some power settings on your PC are designed to use less power from your battery to make it last longer. You can view and change settings to balance your PC the way you want to between higher performance and longer battery life.
Open Disk Clean-up
This tool deletes unnecessary or temporary files on your hard drive so that you can increase the amount of free storage space.
For more information, see Deleting files using Disk Clean-up.
If you feel comfortable using them, you can run advanced system tools such as Event Viewer, Optimise Drives and System Information. You can also view notifications about performance-related issues and what to do about them. Issues at the beginning of the list are impacting your PC more than issues listed further down.
The Windows Experience Index provides a summary of your PC's capabilities. It shows you which parts of your PC are performing best and which might be slowing things down. For more information, see What is the Windows Experience Index?
Using Task Manager, you can improve your PC's performance by preventing unnecessary applications from running automatically when Windows starts.
Open Task Manager by swiping in from the right edge of the screen, tapping Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Search), entering Task Manager in the search box, tapping or clicking Apps, and then tapping or clicking Task Manager.
