The first one is Advanced Vista Optimizer from Systweak. The application has multiple built in accessories. The Advanced Vista Optimizer contains a plethora of tools (around twenty-five) in a single user interface. Apart from regular cleaning of the Windows Vista-based Computer of the temp files and cookies, it also includes some features that enhance your system performance. Some of these include the disk defragmentation, Windows system registry cleaning and defragmenting, data encryption, and privacy protection. It also has several tweaks that allow you faster shutdowns and quick booting.
In all, the Advanced Vista Optimizer fixes the Vista errors in the registry and offers you good protection from people who like to peek into what you have been doing. As with any software, the Advanced Vista Optimizer also has a drawback that makes you reboot the computer in order to finish the cleaning. The AVO is free to use for a month and should you wish to use it further, you can purchase it at around $35. However, for a person who would like to use single software for most of his/her privacy considerations as well as other tools, the AVO is a good deal.
The second most popular tool I found is the Error Cleaner from FreeVistaFiles. This software performs cleaning of Windows Vista based computers and also removes Vista errors from the system registry. The Error Cleaner is a shareware, too, wherein you can use the software free for 60 days. If you like the performance, you may buy it from http://www.freevistafiles.com/Error-Cleaner+Error-Cleaner.html. It also includes a Cookie Manager so that you can specify the cookies that you do not intend to delete.
Finally, let us checkout the Windows Vista Cleaner. The fact that the software is not from a reputed brand but created by a freelance programmer makes it even more interesting. However, the interface is almost the same as the Error Cleaner (see the screenshots). The Windows Vista Cleaner is much popular and works well on Windows Vista to remove the temporary and log files. It also removes the cookies and history traces to protect your privacy. The software is also free to try. The best thing about Windows Vista Cleaner is its easy to use interface.
Even though there are several software coming up almost the other day with plenty of claims, not all are reliable. To be honest, some of them can do more damage to your computer than cleaning the Windows Vista based computer. I will still recommend that you use Comodo System Cleaner in conjunction with CCleaner to keep your computer clean and safe. These software have been around for considerable time and have proven to be among the best ones. The actions performed by these two software are enough to remove junk, privacy traces, and to scan and remove Windows Vista Errors from the system registry. The best thing about the Comodo System Cleaner and CCleaner is that despite the popularity they enjoy, they are still free to use for a lifetime.
