Was The Windows Registry A Good Idea?
However, you can read more about all three here, here, and here, respectively. The easiest way to do this in all versions of Windows is to open the Run dialog box via WIN+R, and enter regedit.
They are not interchangeable, nor are they hot-swappable. A self-diagnostic program used to perform a simple test of the CPU, RAM, Video, and I/O devices. The POST is performed by the startup BIOS when the computer is first turned on, and is stored in ROM-BIOS. If POST encounters any errors it will display an error code on the screen, sound a series of beeps which indicate what type of error has occurred, or both.
Although HKEY_LOCAL_MACHINE is often written as HKLM, it’s not really an "official" abbreviation. This is important to know because some programs in some circumstances, even tools available directly from Microsoft, don’t let you abbreviate the hive in registry paths. If you’re getting an error while using "HKLM," use the full path instead and see if that fixes it.
Because of this non-existent nature of HKEY_LOCAL_MACHINE, neither you nor any program you install can create additional keys under HKEY_LOCAL_MACHINE. In other words, HKEY_LOCAL_MACHINE acts like a shortcut to a number of other sources of data about your computer.
- The registry was introduced in Windows 3.x, not, as is commonly believed, in Windows 95.

A Command Line Interface allows the user to interact with the OS using typed commands or scripts rather than a GUI. The disk must contain at least one partition, typically allocated a drive letter, and the partition must be formatted with a suitable file system.
Most of the time these keys appear blank when you open them and/or contain subkeys that are blank. HKEY_CLASSES_ROOT is a global hive, which means it can contain information that applies to all the users on the computer and is viewable by every user. This is in contrast to some hives that have information that applies only to the currently signed-in user. While you can edit and completely remove any subkey inside the HKEY_CLASSES_ROOT hive, the root folder itself, like all hives in the registry, cannot be renamed or removed. What ProgID, CLSID, and IID keys are for are related to some very technical aspects of computer programming and are beyond the scope of this discussion.
Always remember that the registry in Window is a crucial for your system. If it were not so important, there wouldn’t be so many tools available to help you "clean" it.
