My probably unpopular opinion is that the registry is the worst feature in Windows. It’s bloat directly impacts the speed of the operating system.
Seems like such a waste for so many advancements in Windows but the registry sticks around like a bad hangover.
Also there is nothing like "bloat". No process needs too loop around or smth like that, so there is literally no way to have a forgotten registry item slowing down your PC.
And last but not least: What are the alternatives? .plist config files like with Apple, scattering around the system?
The critique against the Windows registry stems from the Windows 95 days when the registry could become corrupt and repair or reinstall was necessary. However since then the registry works like a database, it has transaction logs and simultaneous writes are atomic. Registry is also strongly typed, not a bunch of strings. Registry can easily be backed up and restored.
Do you have any evidence of this? I remember in the XP days the German c't computer magazine tested populating the registry with hundreds MBs of garbage and found no performance impact at all.
I do not really think one is better than the other.
I don't see any alternative on where entire OS could be configured other than registry.
