Registry problems usually start when some unwanted data strays into or gets left behind within the registry and causes registry bloat. Some of the common causes that give rise to this unwanted data within the registry are:
- Orphan and empty registry keys left behind when programs are uninstalled from the system.
- Outdated keys left behind when programs are updated.
- Installation of faulty programs that add incorrect registry entries.
- Frequent changes in the system configuration.
- Browsing malicious Web sites.
- Virus and spyware infections.
- System crashes.
- Malfunctioning hardware.
- Problems within installed programs and device drivers.
The accumulation of unwanted information within the registry due to these activities increases the registry size at an uncontrollable rate and causes registry bloat. A bloated registry causes several problems on the PC. Some of the common problems that you may face due to registry bloating are:
- Entries in the registry may get corrupt and generate several computer errors.
- Data access from the registry may slow down resulting in reduced performance of your system.
- Your system may start crashing and freezing up more often causing unnecessary frustrations.
- In more severe cases, the registry may crash and render your system unbootable.
