Windows 7 slow down - Page 2

post #11 of 19
If your computer is infected so is your array. Either way you may end up formating your array. Back up the reliable files in your Program files (and if you have 64 bit, your x84 Program files as well) but do not back-up anything suspicious if you do have to format.

The registry doesn't cause too much slowdown. I've discussed this in too many threads. In order for it to do anything severe it has to be pretty messed up. File fragmentation is probably the cause. Or even just low disc space, though I would say file fragmentation.

What I would do is try and remove some free space and delete the pagefile. It'll re-build the pagefile and hopefully do it so it's not all crappy and fragmented.

If that doesn't help I would then move to AV software/services and shut them off/prune them.

If you can't prune files, services, and no general "cleaning" helps then you might want to look at formatting.

[note] Look at removing restore points to free up space, if you don't pay attention they can build up taking a lot of room. This can make space disappear and cause inner file fragmentation. You may also want to think about freeing up a lot of space, 20G or so and do a full defrag. While I don't like suggesting that it might help.

[edit: note on restore points and inner file fragmentation] Since restore points have a lot of small files it increases the chances of fragmentation and inner file fragmentation. The more files you have the worse it gets. Although once you start getting a lot of inner file fragmentation it becomes hard to remove. You have to replace the file with a new one, can be as simple as deleting the file and then copying a replacement in. This has to be done though because files that have inner fragmentation will stay fragmented until they get replaced. This happens with all fragmentation though, it doesn't go away until the files are replaced or "moved". Moving them can get rid of general fragmentation but not inner fragmentation, something people don't really recognize.

Can you explain how broken/missing registry keys and such wouldn't cause a system slowdown? I'm interested.

broken/missing registry keys cause errors, which could cause a slow down but you will know it's broke.

Registry fragmentation is almost non-existent. Mainly because it's all organized very close to a b-tree. When a program calls for the registry key it looks in a specific place. Why do you think the registry key is organized in multiple hierarchies?

hkey_local_machine/software/microsoft/windows/current version/run

Specific locations! So when a registry key is called the program generally knows where to look. Also programs are quarantined, or sandboxed, they can't see keys that the system won't let them see. It is also why you have multiple hiv files, each user has his own hiv file for personal stuff ect... ect...

It's the structure that makes the registry so efficient, as well as the fact that we don't use it in Vista/7 nearly as much as XP. A lot of the keys are optional these days where they were mandatory prior. If the key isn't there default values are put in, generally it doesn't matter as nobody changes the default values anyways.

Oh, and there are backups of the registry, so if a key is missing it can go and check the original backup hiv files and insert a new one.

[edit] Seriously, I've gone over this OVER AND OVER with people. The registry isn't that complicated, it's no more complicated than an SQL database. In fact it's closely related.

First download and run ccleaner; ccleaner is a really great program that just clears crap from your computer. It also does registry cleanup. Finally, go to msconfig and turn off all the unnecessary programs in startup.
Edit: its also free too

cleaning the registry does nothing to impact performance. It's like trying to prune a couple hundred lines from the book "The Stand" and then claiming you are now able to read it much faster.

[edit] The stand is roughly 1000 pages, a couple hundred lines won't even put a dent in it.

Regardless, ccleaner is still useful for clearing other items that could be causing a slowdown

have you tried msconfig to see whats starting when you turn on your computer if not
go to start button click on it in the run box type msconfig click on misconfig go to startup tab and turn off programms that start when the computer starts that should help speed up your startup
also install ccleaner that helps to keep your computer running faster by removing leftover files explorer history ect

Everything on that list is minimal when it comes to system performance. You can throw out all the browser stuff, that's moot unless you experience specific performance problems with browsing.

Code:
Recycle Bin, Recent Documents, Temporary files, Log files, Clipboard, DNS Cache, Error 
Reporting, Memory Dumps, Jump Lists.
Temp files, documents, recycle bin, and... I think that's all in that list that will hinder performance. Though removing temp files can hurt performance as a lot of those are stored/cached for future use. As well as the DNS cache is there to aid your system, you only should need to clean it if it gets messed up.

Anything else, as far as system performance, can be ignored. That entire section on "other programs" is moot, as you can just shut off all services and keep them from running until explicitly called.

ccleaner is moot, always has been always will be. I'm not saying you shouldn't use it, just too much advice saying it really helps performance.
