Windows 10 quick tips: 12 ways to speed up your PCTime: Jun. 16, 2019
Change your power settings
If you're using Windows 10's Power saver plan, you're slowing down your PC. That plan reduces your PC's performance in order to save energy. (Even desktop PCs typically have a Power saver plan.) Changing your power plan from Power saver to High performance or Balanced will give you an instant performance boost.
Disable programs that run on startup
One reason your Windows 10 PC may feel sluggish is you've got too many programs running in the background -- programs that you may never use, or only rarely use. Stop them from running, and your PC will run more smoothly.
Shut Off Windows Tips and Tricks
As you use your Windows 10 PC, Windows keeps an eye on what you're doing and offers tips about things you might want to do with the operating system. I my experience, I've rarely if ever found these "tips" helpful. I also don't like the privacy implications of Windows constantly taking a virtual look over my shoulder.
Windows watching what you're doing and offering advice can also make your PC run more sluggishly. So if you want to speed things up, tell Windows to stop giving you advice. To do so, click the Start button, select the Settings icon and then go to System > Notifications & actions. Scroll down to the Notifications section and turn off “Get tips, tricks, and suggestions as you use Windows.”
That'll do the trick.
Stop OneDrive from Synching
Turn off search indexing
Clean out your hard disk
Clean out your Registry
Disable shadows, animations and visual effects
Launch the Windows troubleshooter
Windows 10 has a very useful, little-known tool that can sniff out performance problems and solve them. To launch it, run Control Panel and select System and Security > Security and Maintenance > Troubleshooting > Run maintenance tasks. A screen titled "Troubleshoot and help prevent computer problems" will appear. Click Next.
The troubleshooter will find files and shortcuts you don't use, identify any performance and other issues on your PC, report them to you and then fix them. Note that you may get a message that says, "Try troubleshooting as an administrator." If you have administrative rights to the PC, click it and the troubleshooter will launch and do its work.
Get help from the Performance Monitor
Shut down and restart Windows
Here's one of IT's not-quite-secret weapons for troubleshooting and speeding up a PC: Shut it down and restart it. Doing that clears out any excess use of RAM that otherwise can't be cleared. It also kills processes that you might have set in motion and are no longer needed, but that continue running and slow your system. If your Windows 10 PC has turned sluggish over time for no apparent reason, you may be surprised at how much more quickly it will run when you do this.
