ImproveSpeedPC is a potentially unwanted program (PUP) that is found as PUP.ImproveSpeedPC. PUP.ImproveSpeedPC may deploy a high-performance algorithm to its one click scan that quickly identifies missing and inaccurate references within the Windows Registry. ImproveSpeedPC may scan the entire Windows Registry for all invalid or obsolete entries and generate a list of errors found. PC users may then choose to clean selected errors or repair all of them. Windows Registry's main function is to store a computer system's configuration. Installing and uninstalling a program may clutter the Registry, which may lead to poor PC performance, system crashes and data loss. During the setup, PUP.ImproveSpeedPC may create a start-up registration point in Windows in order to automatically load when any computer user boots up the PC. A scheduled task may be added to Windows Task Scheduler in order to run PUP.ImproveSpeedPC at various scheduled times (the schedule may vary depending on the version).
