Keeping your hard drive properly defragged is one of the easiest ways to speed up your system and ensure that everything runs smoothly and quickly.

You can launch the program either via shortcut, Start menu or the command line with "QREGDEFRAG.EXE -defrag". Other command line commands you can use are "-defrag" which operates defrag in "silent mode" and "-noprogresswindow" which hides the progress window during defragmentation. Finally, you can also use "-reboot" which automatically reboots the computer when defragmentation of the registry is complete. If you're using Vista, note that you'll also have to run the program in administrator mode. The big question, as with all defraggers, is does the program operate quickly and does it have a noticable effect? Whether it runs quickly depends on how badly un-defragged your hard drive is and of course, how big it is. Generally, the program runs at an impressive speed, especially under Vista but it doesn't seem to make any particularly impressive speed improvements. However, it does make programs open slightly quicker and presents a full report on defragged files.

A quick and speedy defragger that helps programs open faster and allows you to see at a glance, those files that are slowing your system down.

Registry errors are one of the main reasons for the slow operation of your PC or frequent crashes. Baku can ensure that if your registry does have malicious entries, they can be removed safely. Baku also deletes empty folders, 'History' folder contents, 'Recent documents' folder contents, 'Temp' folder contents and temporary internet files. It can also search Windows log files, shortcuts to missing files and folders and user specified file types. The registry scan itself aims to remove unused and obsolete keys, including ActiveX, Application Paths, Fonts, Help files, Icon files and pesky uninstallers.

Like all such programs, it backs up your registry in case of any wrongful changes although I found that this wasn't exactly easy to restore. Probably the most useful function is the registry compacting facility which does seem to make a notable difference to the running speed of your PC. The developers claim the program uniquely works by recreating each registry hive "from scratch", thus removing any slack space that may be left from previously modified or deleted keys. Note that this function does NOT change the contents of the registry in any way, nor does it physically defrag the registry files on the drive. Be warned though that it takes a little longer than programs such as CCleaner and you'll have to wait more than few minutes for the registry backup to be made.

Normally I use CCleaner for my registry cleaning requirements but AML Free Registry Cleaner offers a level of registry cleaning and penetration much deeper than that.

One of the biggest problems with Windows, and what has many people jumping ship for Macs, is that it suffers from clogged and infected registries.

Registry Clean Expert scans your Windows registry and uncovers incorrect or obsolete information in the registry which in theory should speed up your machine. However, don't get too excited because whatever is slowing down your PC may not even be related to your registry - it could just be a case of a trojan or malware that's infected your hard drive. Also be careful because any changes you make to the registry, can destabilise your system. However, Registry Clean Expert does give you the option to rollback any changes you've made with the backup/restore function.

The most useful function for me though was that you can also edit an manage BDO items in your startup sequence. BDO items are those items which launch themselves when you turn on your system. They are usually entered in your registry too and if your system is taking increasingly long to start up, then you may well find that it's the BDOs that are causing the problems.

While it may not always fix your registry, the BDO cleaner will certainly speed up your startup's and shutdowns.

A computer is very much like a car in the respect that it's all clean and speedy when you first get it but after a short while it starts to slow down. And just as your auto needs a tune-up every once in a while, so to your PC can be given the once over to speed it up. Registry Mechanic is one of a number of registry cleaners on the market, and it also proves to be one of the best.

Trawling through your registry for problems can be a tricky and even dangerous task, but this program makes it really simple to cut the crap that you don't need through its idiot-proof navigation. The app splits registry errors into categories, prioritising their importance and offering you a simple-to-understand description of what the problem is.

Every PC owner faces the problem of slow computer syndrome at some stage and one of the most common causes of this frustrating issue is the Windows registry. In brief, this is a database that stores configuration information about all the hardware and software on your system and does so for each user account. Through persistent use, entries become redundant or unorganized, which is why users need some way to sort it out from time to time. RegCleaner attempts to provide a solution to this problem but does it deliver the goods?

What you get is a small program that displays the data that holds your Operating System together. It does so using the raw values and as such, some of the entries may seem mystical to anyone that doesn’t have much experience of the Windows registry. For users who do know their way around, however, they will find this utility to be efficient and useful for weeding out any lingering entries such as unused file types, “dead” uninstall information, or unwanted startup services.

There is an automatic scan but it seems to be geared towards manual removal of entries. Good for quickly removing multiple keys, the lack of a confirmation dialog could lead to disaster, but as you work through various lists, everything you affect is backed-up, should you accidentally get trigger-happy.

We like the no-nonsense interface of RegCleaner, which suits users who have clear objectives in mind before opening the program. Conversely, if you aren’t confident around the registry, don’t expect any spoon-feeding from here. For that, you may want to look to alternatives such as Registry Repair or Registry Booster.
