4 PC Speed up Software That Really Work to Tune up Windows Computer

Windows PC slow speed

So your Windows PC is running very slow, and you are told that a system optimization utility can help. It's true that you can rely on a PC speed up software to fix many types of system issues thus tune up its performance more cost-effectively, instead of buying a brand new computer.

We have to warn you, however, that many so-called PC speed utilities do more harm than help. Some are not safe to use at all as they can't pass the eye of an antivirus scan, some are white-labelled registry cleaners that exaggerate the number of PC errors or issues.

What's the best PC tune up software? Here are the top 4 tools we recommend based on our testing or using experiences.

How Do We Select These System Utilities? — The Criteria

  • Security: any downloadable applications shouldn't contain any virus or malicious processes. To test it, we first download and install a utility. Then use BitDefender and MalwareBytes to run a full scan of the system to see if the installed program contains virus/malware or does other kinds of harm.
  • Performance: this is the core part of our testing. An ideal PC system optimizer should do what it says. If it can't improve our PC performance, then it's more like a scam or a low-quality product. Since different utilities have different features and functionalities, we try to run each of them hoping it will increase our system performance a little bit. Finally, we observe the performance of our PCs to see if the software really makes our PCs faster.
  • Ease of use: a good PC speed up software must be powerful, but also user-friendly — easy to use for users of all levels. To be honest, there are no universal standards to follow before we make our judgments. Thankfully, human instincts are usually correct especially if you have used dozens of them and the winners stand out of the crowd.
  • Support: a great product with bad customer/technical support makes the product less impressive. We value the software more if their developers offer detailed user manual, tutorials, email support, or even live chat or phone support.
  • Compatibility: we test if the software is compatible with modern Windows operating systems such as Windows 10, 8, 7, etc. If a PC speed up tool does not support latest Windows 10, that indicates the software lacks an update.
