Don’t be scared to reboot your computer if its not working properly. This can fix alot of problems and it is faster than attempting to manually troubleshoot and fix the problem yourself.
Close System Tray Programs
Many applications tend to run in the notification area. These applications often launch at startup and stay running in the background but remain hidden behind the up arrow icon at the bottom-right corner of your screen and these applications might make your PC perform slower than you expect it to. To remove these applications from the system tray, click the up arrow icon close to the system tray, right-click any applications you don’t need running in the background, and close them to make your PC run better than it is running.
Scan for Malware and Adware
Malicious software running in your PCs background can also make your computer work slowly. This may not be flat-out malware, it may be software that interferes with your web browsing to track it and add additional advertisements, for example.
To make sure you are extra safe, scan your computer with an antivirus program like Avast or Avira. You should also scan it with Malwarebytes, which catches a lot of “potentially unwanted programs” (PUPs) that most antivirus programs tend to ignore. These programs find their way into your computer when you install other software, and you almost certainly don’t want them.
Free Up Disk Space
If your hard drive doesn’t have much space anymore, your computer may run slower. You don’ need any app to make it run faster, just running the Disk Cleanup tool included in Windows can help quite a bit. Get rid of unnecessary things on your computer and it would start running faster.
Lighten Your Web Browser
If you use your web browser a lot, so your web browser may just be the reason why your PC works slower. It’s a good idea to use as few browser extensions, or add-ons because these things slow down your web browser and cause it to use more memory.
Go into your web browser’s Extensions or Add-ons manager and remove add-ons you don’t need. You should also consider enabling click-to-play plug-ins. Preventing Flash and other content from loading will prevent unimportant Flash content from using CPU time.
Uninstall Programs You Don’t Use
Uninstalling of some programs you don’tuse would really help your PC perform faster. To get rid of those programs you don’t use; open the Control Panel, find the list of installed programs, and uninstall programs you don’t use and don’t need from your PC. This can help speed your PC up, as those programs might include background processes, autostart entries, system services, context menu entries, and other things that can slow down your PC.
Disable Startup Programs
Stoping those progams from launching at startup to save memory and CPU cycles would also make your computer work faster.
On Windows 8, 8.1, and 10, there’s now a startup manager in the Task Manager you can use to stop some programs on your startup programs. To do this, Right-click the taskbar and select “Task Manager” or press Ctrl+Shift+Escape to launch it. Click over to the Startup tab and disable startup applications you don’t need. Windows will helpfully tell you which applications slow down your startup process the most.
Reset Your PC / Reinstall Windows
If tips above didn’t fix your PC’s problem, the best solution to fix Windows problems aside from rebooting your PC is to re-install a fresh Windows on your PC.
On Windows 8, 8.1, and 10, it’s easier to re-install Windows than ever. You don’t have to get Windows installation media and reinstall Windows. Instead, you can simply use the “Reset your PC” feature built into Windows to get a new, fresh Windows system. This is similar to reinstalling Windows and will wipe your installed programs and system settings while keeping your files.
