Why Windows still uses registry?

The registry helps Windows manage and operate your computer, ensuring access to critical resources and helping important programs configure settings. A hierarchical database structure of keys and values makes up the registry.

What is the major disadvantage of using registry in Windows?

Windows registry disadvantages are as follows: Transferring per-program user settings between Windows machines is tedious, as the Windows registry is largely dependent on the local machine.

Why is searching the registry so slow?

Because the Windows registry is a hierarchy, the way regedit is laid out makes typical searches inefficient and slow. Typically, when performing a search in regedit, you highlight the first line ('Computer') and then perform the search.

What is one of the disadvantages to incorrectly editing the Windows registry?

Incorrectly editing the Registry can result in an unstable system, or a system that won't even start. Use of the Reg command and the Regedit.exe or Regedit32.exe utilities should be left to experienced administrators or programmers only.
