How do I speed up my PC?

A PC optimizer can speed up your PC by troubleshooting your device, scanning your drives for any unwanted data or unnecessary software, and cleaning up storage space. If you’re not using a PC optimizer or you wish to assist the application in optimizing your device, you can manually uninstall unnecessary software, limit your programs at startup, clean your internal drive, and reboot your computer.

Why is my PC so slow?

One of the common reasons why PCs get slow is the number and the demands of the programs you’re running. Some programs take up a lot of processing power, impacting the performance and speed of your PC. Other common causes include insufficient disk space, unnecessary software updates, outdated drivers, hardware failure, outdated programs or devices, and malware.
