Should you Care for Your Windows Registry Health?

[Guest jeremiah wright]

What are Windows registry? Why are they so important for your

operating system? What can you do to keep them reliable?

According to Microsoft site, registry are "a central hierarchical

database used in Microsoft Windows ... to store information necessary

to configure the system for one or more users, applications and

hardware devices." You can add to that data regarding file types like

what application is used to open them, what icons should be display

for them and so on.

I will try to explain what's happening on 2 of the most common

scenarios that take place on your computer:

1. You get a new program (software or game). You want to give it a

try, so you install it. At that point, new data is written in your

windows registry. That data include program folder, associated files,

various settings that are used by the program, whether it will run on

startup (HKCU/Software/Microsoft/Windows/Current Version/Run/ ) or

only at the first startup (HKCU/Software/Microsoft/Windows/Current

Version/RunOnce/ ). No problem so far. But what's happening if you

decide to uninstall it? That's that point where things get tricky.

Even if you receive a "successfully uninstall" message, pieces of data

remain in your registry. Of course, this is not happening on all

cases, but sadly it does in many of them. In a worst case scenario, if

for instance files "*.abc" are registered to an application that you

just removed and the whole registration process wasn't properly

removed from registry, you will get an error when you try to run that

sort of files. Those invalid registry entries won't bother you visibly

all the time, but they will cause your computer to slow down or even

crash in some cases....

No, they won't slow down your machine and no, they won't

crash it.

 

It's the same with a hard disk: Having lots of files stored on

a disk will not slow down a machine (but having a large

number stored in a single folder will slow down access to

that folder).
