How Do We Select These System Utilities? The Criteria We Use

Then use BitDefender and MalwareBytes to run a full scan of the system to see if the installed program contains unsafe procedure.
  • Performance: this is the core part of our testing. An ideal PC system optimizer should live up to what it claims to do. If it can't improve our PC performance, then it's more like a scam.

If it doesn't, we ditch it.

Most of the time we have a correct say on whether a software product is well-designed or not.
  • Support: even a great product with bad customer/technical support makes the product less impressive. We value the software more if the developer offers detailed user manuals, tutorials, email support, even live chats or phone calls.
  • 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 If a PC speed up tool does not support latest Windows 10, that's an indication that the software may be outdated due to lack of updates.
