Wise PC Engineer offers a collection of PC cleanup and maintenance tools, designed to optimise your PCs performance.

The Disk Cleaner, for instance, scans your hard drive looking for junk that can safely be deleted. It identifies these leftovers by extension (assuming that, say, *.tmp files are temporary), which is a little riskier than simply deleting your browser cache and the contents of your Windows temporary folders, but can also recover much more drive space.

The Registry Cleaner similarly locates redundant Registry keys, but places a greater emphasis on protecting you. Once your system has been scanned, the program will evaluate the consequences of deleting each key, and recommend you delete only those that it's sure can be removed safely.

Once you've tidied up a little, the program's Registry Defrag tool will compact your Registry files to ensure they're taking up the minimum of RAM and hard drive space.

A simple defragger can then optimise your entire hard drive to improve its overall performance.

And there's also a file undelete tool, though this is poor by comparison with the rest of the package. It scans your drives for deleted files, but to locate them you must know exactly where they're stored, and navigate there through your folder tree (more difficult than usual as the folders aren't even in alphabetical order).

You can schedule the disk and Registry cleaners to run on a regular basis, at the time of your choosing.

And while they're not available in the trial, if you buy the program you'll also get a few other options. These include a secure delete tool, which wipes away confidential files so they can't be recovered; a System Optimizer will help ensure your PC's settings are delivering the best possible performance; and a 1-click tuneup option performs your chosen optimisations at a single click.
