I would have thought a binary or n-ary tree implementation and proper search algorithm would be superfast even for very large registries, is it the actual lookups that are slowing your PC down ? (One would swear a sequential search is being used)

Because you are running Windows 95?

My PC does not get slow.

C:\>systeminfo | find /i "install date"
Original Install Date: 20/05/2010, 12:16:17 PM

Still running as fast as the day it was installed...

The Windows registry is quite complex and quite massive with hundreds of thousands of records. That said, the last time I noticed performance issues from the registry was in Windows XP days.

What do you mean by "slow down your PC"? Do you mean general operation, startup / logon times, game performance or just launching applications? Do you have any evidence your registry has a detrimental impact on your system performance?

:wtf:
 
I'm working on different computers: as you know a computer that felt normal quickly feels very slow once you work on a faster computer, so I'm guessing that's it then (if the registry does not hog up your PC on Windows 7 like in XP). Unless there is some malware not detected yet.
 
Please dont come in here with your SSD crap, yes its good to have if you need a purpose for it.

I wouldn't say it can't, but in most cases, it shouldn't.
I believe the registry is cached in the system cache. If the memory is under pressure for applications, it will remove some of the cache to make space meaning the disk will be hit more frequently to serve registry requests, however in most cases, there are many other factors that could impact a PCs performance.
If it is just a slower PC, then maybe that's just it, but there are a lot of factors to consider.

Nice query - very handy.
