There's one rather popular registry cleaner not included in the test: RegVac Registry Cleaner (Super Win Software). I'm curious to see how its score would have been...

From a quick read:

In the Featured Products table:

    Prize should be Price

    The one instance of 29.95 euros probably should be 29.95 dollars
In the Registry cleaning engine accuracy comparison, round 2 table:

    It is not immediately clear (to me, anyway) what these results mean.

    Maybe I have to think about it longer (ouch).

"Prize" fixed, thanks! The euros are correct, see: http://www.pctools.com/registry-mechanic/purchase/

The result table shows how many of the manually inserted registry errors and how many false positives the products find. So the larger the number in "positive" the better, the smaller the number in "false positive" the better. There was a problem in the table, the data didn't match the column captions, this is now fixed.

You are correct, if/when we do a followup study it will be included as well.

Registry cleaning engine accuracy comparison, round 2

The test environment's registry was manually modified to contain 2000 registry entries of test data, 1000 entries to test for false positives (i.e. registry data that might look like invalid but is in fact valid) and 1000 entries to test for positives. Only the products that contain a way to search for or filter the results were used.

Since, according to the table, PT2009 found 1150 positives, one might wonder where the extra 150 came from …

Under the "Registry cleaning engine accuracy comparison, round 2" table, this phrase occurs four times:

    to accurate count the results.

This is better English:

    to count the results accurately.

Well that's indeed strange. For me the page shows euros, I would understand that if I would enter their site from a computer inside Europe but I'm not. Well, I changed their price to USD in the page, I guess that's somewhat right.

You're in Grenada or thereabouts, right? Maybe if the user's IP is non-USA, they substitute euros. An instant ~50% increase! That would be tacky.

A comparison of trial period (where applicable) terms and conditions would be revealing ...

Yeah, good idea. Registry Mechanic for example was almost impossible to review because the product was so full of nag screens. For example just clicking a registry error on the results list would pop up a nag screen.

This is THE comparison I wanted before deciding on the purchase of a registry cleaner. Indeed, there are tons on the market and most are touted as THE best. Many have their devotees. Some indeed appear to remove more "Empty" "Invalid" or "Unused" entries than others so its tempting to call them "better". After reviewing the JVT PT 2009 Manual and each of the capabilities of this "cleaner-upper", I defy anyone to show me a better one. As a long term user of an earlier version, I found it an easy task to pay the minimal upgrade fee. You can't beat an offer that includes 5 pc's for the price of 1 license! I've never had a crash or freeze up using the old version so I have every confidence that this 2009 version will serve me well. I'm NOT a "power user" by any means. I believe in the dictum: "Don't try this at home.... :lol: " but my machines run just fine between the defragging and the cleanup. I keep the compact antivirus software (NOT Mr. Nxxxxn) and the latest sp's for my O/S current as well. Thanks Finnish Friends!
