Tip #1: Use the performance troubleshooter. The Windows built-in performance troubleshooter locates issues that slow down performance (multiple users, multiple running programs, etc.) and automatically fixes them.
Start > Control Panel > System & Security > Find & Fix problems > System & Security > Check for performance issues

Tip #2: Delete unnecessary programs/software. Always keep only those programs that you require for your everyday use. Unnecessary pre-installed programs such as trial versions of software, anti-virus programs, PC cleanup tools, and data backup software run in the background – consuming disk space, memory, and CPU power; thereby slowing down your computer. Uninstall all such programs that are of no use to you.
Start > Control Panel > Programs > Uninstall a program

Tip #3: Disable unnecessary startup programs. Several programs run automatically when you start Windows. These programs can slow system performance. You can decide which startup programs you want running and disable the rest. Look for startup programs running in the background on Windows Taskbar and click Show hidden icons to view all live background programs.

Tip #4: Use Disk Defragmenter. Defragmenting your hard disk is a good way to ensure optimal system performance. The Windows Disk Defragmenter utility helps rearrange fragmented data and ensures that the hard disk performs efficiently.
Start > All Programs > Accessories > System Tools > Disk Defragmenter

Tip #5: Use Disk Cleanup. Unnecessary and unused files on your computer can reduce performance drastically. Use the Windows Disk Cleanup utility to delete the cache, temporary files, and other unused system files.
Start > type Disk Cleanup in the search box

Tip #6: Use Disk Check. Errors on the hard disk also slow down performance considerably. Use the Windows Disk Check utility to check for hard disk errors if any, and recover readable data.
Start > type cmd to go to the Command prompt > type the command – chkdsk /r

Tip #7: Limit the number of programs and browsers in use at one time. Some people have the habit of opening multiple programs, files, and internet browsers all at once. This consumes disk space and slows down performance. To ensure that your PC speeds are consistent, keep only such programs and files that you are working on. Having multiple anti-virus programs can also slow down your PC. Make sure you have only one reliable anti-virus program.

Tip #8: Do away with visual effects and unnecessary graphics. Performance definitely scores over appearance when it comes to Windows. If your PC is running slow, chances are the high-performance graphics and high-end visual effects are causing this. It is best to eliminate such graphics and visual effects that can hinder system performance.
Start > right-click My Computer > Properties > Advanced system settings > Advanced tab > Performance > Settings > Adjust for best performance

Tip #9: Check regularly for viruses, spyware, and malware. The most noticeable symptom of a virus is a slow-performing PC. Always update your anti-virus software and scan your PC regularly. Spyware and malware from the internet can cause serious harm to your computer, besides slowing performance. Use Windows Defender or any other reliable anti-spyware programs and run routine checks. You can also run scheduled scans for viruses and spyware.
Start > type Windows Defender in the search box

Tip #10: Add more RAM. If, after following the above tips, you still feel your computer is slow, it would be wise to purchase more Random Access Memory (RAM). You can also use Windows ReadyBoost to utilize storage space on removable media such as USB devices.

Other useful tips:
