The Windows system registry on your PC is a central database that stores and organizes information used to configure your computer.
The registry basically acts as the data storage locker for all the internal settings of your computer. It organizes information about your user profiles, what apps you’ve installed, and software used to run any hardware devices you have connected to your computer.
Whenever you’re using your computer, Windows is constantly accessing the registry to make sure everything can run.
So, whenever you install software, create a bookmark in Internet Explorer, make changes in your PC’s control panel, or even remove a program, everything is automatically logged in your system registry.
Each piece of information is known as a “registry key“. If you have had your computer for even just half a year or so, your registry is probably storing thousands of such keys to make everything work.
Registry items can also include:
• COM/ActiveX Entries
• Application Paths
• File Extensions
• File Associations
• Install & Uninstall Entries
• Font Entries
• Shared DLLs
• Help files
• Program Shortcuts
• Sound App Events
• Windows Startup Items
• Windows Start Menu
As you might expect, registry keys accumulate over time in your hard drive.
While some registry keys are absolutely critical to make sure your PC operates correctly, in fact a lot of them are duplicates. Some of your registry keys may actually be invalid, or even corrupt. These useless registry keys can slow down your computer.
Useful or not, registry keys places demands on your computer.
Registry keys are hungry for space on your hard drive disk, and they can also drain valuable computing power from your PC.
Windows Must Review Each and Every Windows Key When You Start Your Computer
For example, every time your computer starts up, Windows has to check the registry to organize every single one of your software programs.
If you have a lot of useless, duplicate, or corrupt registry keys it’s going to take a long time from pressing your power button to being able to actually do anything with your computer.
If you have noticed your computer’s overall performance seems to be slower, or if Windows freezes up or crashes every now and then, or if you are starting to receive error messages, then your Windows registry may actually be corrupted.
While you can manually recover a corrupt registry by performing a system restore to return the system returns to a state very close to the state before the problem occurred, this process is time-consuming, somewhat technical, and a little risky.
