When - and why - should you store data in the Windows Registry?

Question

As a developer, tools that store configuration/options in the registry are the bane of my life. I can\'t easily track changes to those options, can\'t easily port them from

Answer 1

• Originally (WIN3) configuration was stored in the WIN.INI file in the windows directory.
• Problem: WIN.INI grew too big.
• Solution (Win31): individual INI files in the same directory as the program.
• Problem: That program may be installed on a network and shared by many people.
• Solution(Win311): individual INI files in the user's Window directory.
• Problem: Many people may share a windows folder, and it should be read-only anyway.
• Solution (Win95): Registry with separate sections for each user.
• Problem: Registry grew too big.
• Solution (WinXP): Large blocks of individual data moved to user's own Application Data folder.
• Problem: Good for large amounts of data, but rather complex for small amounts.
• Solution (.NET): small amounts of fixed, read-only data stored in .config (Xml) files in same folder as application, with API to read it. (Read/write or user specific data stays in registry)
