K9-PCFixer 1.8

Registry optimizer and defragmenter to increase system performance
1.8.243 (See all)
K9 Tools

K9-PCFixer can allegedly help you increase your system’s performance and stability by finding registry issues. The program has a nice interface with a lot of visual support, like the use of gauges and colors. However, it looks too similar to other products, which makes me believe that some of them may be clone versions of the same tool.

The application scans the registry to find various types of problems, such as unused entries left behind by some applications after being uninstalled, shortcuts to inexistent files and defective settings of Com and Active-X components. As scanning the registry usually takes a long time, you can specify what areas to inspect. Luckily, you can examine the full report and decide which problems you want to get fixed. Likewise, you can avoid the dangers involved in messing with the Registry by creating backups. Finally, the tool can also defragment the registry, which has a very positive effect on computer speed.

Buying K9-PCFixer is definitely a big risk because working with registry issues is a “black box” for most users and there are multiple scams out there. The free version of K9-PCFixer certainly finds a lot of problems but fixes only 15 of them, which is no proof of its effectiveness, because it is difficult to see any real performance improvement after such a small change. In my opinion, if the developers of K9-PCFixer really want to guarantee their program’s validity, they should be more generous in terms of the number of issues fixed. The bottom line is that in a market practically flooded by system optimizers, K9-PCFixer does not really have much to offer.
