There could be multiple reasons for that. There could be too many processes running on startup or on the background when your PC is working. These processes, if too many, will significantly decrease startup speed and the speed of the PC as a whole. Another possible reason could be having installed more than one antivirus programs, firewalls, internet security systems. By doing that the only thing that changes is your computer's speed. You are not protecting it more, you are just making it slower. No need. Your disk could be very fragmented. When you install and deinstall programs or when you create and delete files, gaps in your registry occur and finding the necessary files for operations gets slower and slower. Your Windows registry is cluttered. Your registry keeps all your Windows and other applications' settings. When you install and remove software, there are always residues that need to be removed.

Do a scan with SweepTools PC Cleaner. Once it is completely ready with the scan let SweepTools PC Cleaner use its powerful cleaning, repairing and defragmenting tools. SweepTools PC Cleaner will do all the work for you!

When too many applications launch at startup, your computer need more time and resources to start it all. With SweepTools PC Cleaner you can decide which processes you want to leave and which ones you do not need.

Your operating system and all applications installed on it create temporary files during installation and when running. This happens constantly. In this way hundreds of thousants of temporary files get created while programs work.

Most of your temporary files do not get cleaned out from your hard drive even if they are no longer needed. The amount of files that is created grows contantly, takes up more and more space and slows down any running process on Windows.
