With my experience with windows, I would get my computer and it would be fairly fast when first using it.
After awhile things that used to be done fast or instantly, started taking a long time.
The thought was that it was a virus, spyware, or adware problem slowing down the machine.
After using all the tools and finding there were none of these, I just reinstalled windows because I wanted the speed back.
What I didn't realize at the time was that a registry clean up software could have helped with these speed issues.
As programs are installed and uninstalled due to the nature of this registry found on windows machines, eventually the computer applications can start to slow down significantly.
For an average computer user, using a registry clean up software is about as easy as using a virus scanner or adware remover.
Reinstalling a complete operating system along with the drivers is a much more complex process.
What's nice about a registry cleaner is that it can also get rid of errors that you see on start up.
Sometimes when something isn't properly removed the computer is looking to start the program when the computer starts.
When it can't find certain files or dependencies, the gray pop up box will let you know that this file no longer exists.
These are quite annoying.
For the expert user this can be edited in the registry and taken care of.
But the average user trying to edit the registry can cause unwanted effects.
Instead of getting a brand new computer or looking for a complete reinstall of the operating system, try a registry cleaner software to regain that speed.
