Working on a slow computer is frustrating; your programs keep on crashing, the screen freezing, and whatnot. Waiting endlessly for the cursor to stop spinning becomes a constant affair.

Do you recall the speed of your computer when you first bought it home?

It used to perform all the tasks in a flash, saving time and letting you relish your work. But with time, its performance and speed started becoming slow as a snail.

So, what’s the real reason why Windows desktop or laptop becomes slow after a while?

Well, a plethora of reasons are responsible for the deterioration of your computer’s health, affecting its overall performance. The biggest one of them is excessive usage. Many people around the globe use their computers every single day, which makes the system cluttered with programs, files, registry keys, music, videos, and many more.

Your computer’s operating system manages all the resources, including memory, processing power, and drive space. So, several things contribute to slowing down its performance and speed, such as:

  • Filling up of disk space (SSD or HDD)
  • Running out of Random Access Memory (RAM)
  • A large number of startup and background programs
  • Fragmented or old hard drive
  • Lack of updates on driver or Windows
  • Virus or malware
  • Using visual features and special effects
  • Using so many add-ons on the browser
  • Possibility of crypto-mining

Hence, your computer slows down significantly enough to drive you crazy. Now, you may be compelled to think about purchasing a new PC.

But wait, are you making the decision so early?

Consider using optimizer software before you treat your computer as a lost cause.

What is a PC Optimizer?

As the name suggests, the optimizer is an application you can use to improve the performance of your computer by optimizing its various aspects. The software includes standard features such as disk cleaner, auto-optimizer, disk defragmenter, register cleaner, etc., that work collectively on your computer to identify unnecessary stuff and eliminate them.

The software’s automatic feature eases the process and saves time while preventing any fatal errors that may occur, like Blue Screen of Death, as in the case of manual optimization.

How does a PC optimizer work?
