Does your computer perform sluggish, do you experience constant freezing,

how about the blue

screens of death? These are all signs of your Windows PC experiencing

registry problems.

The registry is what in the tech industry we call the essential part of every

Microsoft operating

system, ranging from Windows 95 to Windows 8. It’s a database area that

stores information about

the hardware, software, and various configuration settings on your PC. All

the information stored

in the registry is in the form of keys and values. This is vital for the smooth

functioning of your computer. When there is a malfunction to these entries,

failures, system errors, a range of other problems start to happen. Such

instability to the system can make it unusable if the problem is not

addressed in a timely manner.
