There are many tools and software promising to increase the speed and performance of your PC. Most of them are a scam, if not worse.
First of all any software that is always loaded on start up will take resources from your computer and your computer will be slower as a result. Do not trust any software that loads on start up and promises a faster computer.
Some tools promise to free RAM memory, this is not true, Windows already has it’s own tools to manage memory and you do not need any external tool, the only thing you will get is less free memory as the new “false” tool is taking it’s part of the memory.
Some registry cleaners and temporary file cleaners may be OK, as long as they do not load every time you boot Windows. But be careful to install only well known software to avoid spyware scams.
