When it comes to cleaning the Windows registry, my usual first response is to suggest manual cleaning, rather than relying upon third party software to do the job for you. There has always been a reason why I have recommended manual cleaning, and that is because you have more control over what keys are actually deleted.

Most software based registry cleaners simply scan the registry hives, inform the user of, say, 500 or so problems, and then quickly proceeding to suggest deleting every marked problem. Little does the gullible user realise that out of the 500 suggested entries marked for deletion 200-300 may simple be false positives – something the software thinks is a problem, but, in fact, isn’t, and to delete the item(s) could result in a system crash.

Smarter than Average

AMUST Registry Cleaner works rather differently, in that it uses SmartScan technology. If SmartScan is unsure about a particular registry entry it re-scans the registry to find out if the entry is actually valid and important before marking the registry entry for deletion. This effectively eliminates the risk of important registry keys being erased and the registry becoming compromised.

Start as you mean to go on

AMUST Registry Cleaner has a smart, clean interface and is really simple to use. All that is required is that the user presses the Express Scan button and AMUST will do the rest. From here on AMUST scans and fixes registry entries in the following categories.

1. Component subsystem

2. Internet Explorer

3. Shared Components

4. Control Panel

5. Microsoft Office

6. System and User MRU List

7. Associations

Scanning progress is monitored by seven progress bars, enabling the user to instantly see how the scan is progressing.

Taking to Task

The left hand pane of the Registry Cleaner Window contains menu items such as Tasks – Scan & Fix, Report & Undo: Utilities – Backup, Compact: and Options – Schedule, and Settings. These are relatively straightforward in respect of the actions they undertake. Scan & Fix, of course, is the default option when you first open AMUST. However, the most important option to consider, before even considering Scanning & Fixing your registry is that of Backup.

Backup

Backing up the registry is ‘the’ most important task prior to making changes to registry entries. After all, if you make a mistake and you haven’t got a backup then your system can easily fail to boot correctly.

While AMUST does contain an option to backup the registry, it doesn’t actually encourage the user to perform regular backups prior to performing remedial work on the registry. Rather than having the option to backup the registry as a separate button, it would be more preferable for AMUST to have incorporated an automatic backup option ‘prior’ to the application making changes to the registry. I suppose the one consolation is that a backup can be scheduled, from the schedule option window, for a specific time and day, but that is not the same as having an automatic backup option every time you run the Scan & Fix.

Small is Good

As the registry is the heart of the operating system it is accessed every time you use your PC. Consequently, as you add and remove applications, change hardware, and generally tinker with your PCs settings, the registry can begin to become quite bloated. Obviously, as one uses the AMUST registry cleaner gaps will, inevitably, appear in the registry listing. Even though the ‘key’ has been deleted the vacant space still takes up room. A simple analogy would be to think of a list of items written on paper. Now cross out all the things you think don’t need. The list is just the same length, even though you don’t want as many items. To reduce the amount of space the list occupies on the paper, therefore, would require the re-writing of the list on another sheet. In the case of the registry, however, the vacant space can be grabbed back by simply compacting the registry, thus removing all of the vacant space and making the registry somewhat smaller and faster. How small, of course, is dependent upon how much detritus is removed in the first place.

A Time For Everything

Keeping the registry in trim can be a chore, however, AMUST’s scheduling option enables you to set up an automatic Scan, Backup, or Compact on a regular basis, be it Daily, Weekly or Monthly; there is even an option to schedule the scan for when your PC first boots up.

Undo

After cleaning the registry your system should run much better. However, there may be times when things just don’t run according to your expectations. You may, therefore, feel that the registry clean has made things worse rather than better. In this instance AMUST has a simple remedy, Undo. To reverse anything that AMUST has done to the registry all you have to do is press the Report & Undo button and then select the session to undo. Your registry will then be returned to the state it was prior to you using AMUST.

Verdict

AMUST Registry Cleaner is different from other registry cleaners in that it uses SmartScan to determine whether a registry key should be deleted or not. Although this method doesn’t completely eliminate false positives, it certainly does reduce them, making AMUST a far more reliable registry cleaner. If it has a downside, it is the fact that it doesn’t create a backup of your registry during the normal scan and fix process. This is disappointing, particularly if you simply enable the ‘automatically fix all issues’ option. Without the safety net of a backup each time AMUST is run you could be getting yourself into deep water.
