82. How to edit the windows registry
Editing 
the Windows registry can most easily be accomplished through the REGEDIT program 
built into Windows. This can be accessed by going to start\run\ and typing 
'regedit.' 
Due to 
the nature of the registry, any changes you make here do not have to be saved. 
All changes are applied upon restarting the system. This also means that there 
is no 'cancel' button for undoing accidental changes, so make sure you keep 
careful note of the values you intend to edit. 
Registry 
values are stored in keys which appear as folders in the REGEDIT window. Most of 
the following instructions will have you add or edit values inside these 
keys.

When you 
highlight a key in the left pane, the values stored in it appear in the right 
pane. To edit a value, right click it and select 'modify.'
To add a 
new value, navigate to the key in which you wish to add the value, right clock 
it and select 'new' then the type of value you wish to create. Generally this 
will be either a string or DWORD value. Once you have created the value, name 
it, then right click on it to 'modify' its properties.
Note that 
the naming convention for the registry, which we stick to in the following tips, 
is no spaces, separate words indicated by using capital letters. For example:
