The reason the computer gets slow is due to the registry files becoming corrupted, or messed up, in simple terms. These files tell the computer or laptop how to operate the software installed on the system. If any of these files get messed up, the computer is not sure what to do and this will really slow down the computer. The other scenario is where you download other software, screensavers, pictures, videos, or even music, and this will somehow change the settings on a registry file. When this happens, the original program that needs that file now has the wrong instructions in it. So, it will cause the computer to run slow, or in a worse case, crash.
