Baidu PC Faster is a free PC optimisation, cleanup and maintenance suite.
The program has all the regular speedup tools, with modules to remove junk files, clean the Registry, wipe browser and application histories, control your Windows startup programs, optimise your internet connection, free up system resources, and more.
The App Store is a more unusual extra. On installation, it checks for and highlights any missing updates for your applications. But it also provides an easy way to find and install further programs. If you need an Office-type application, for example, you might click the "Business" category, browse to LibreOffice, click "Install", and just wait: Baidu PC Faster will download the latest version and launch its installer for you.
The integrated Virus Scanner is another ingredient you won't find in most maintenance suites. In this case that might be a good thing - it's an on-demand scanner only (no real-time protection), and not very accurate - but it's easily accessible if you need a quick system check.
Bonus extras include a defrag module, file wipe and undelete tools, a context menu editor, LSP repair tool, and more. Some of these are basic, and none are even close to the best of breed freeware, but a few are worth having.
Baidu PC Faster has some problems. Its recommendations can be questionable; several modules are horribly limited; the English language translation is one of the worst we've ever seen in a corporate product ("impact of other startup items may result in ineffective settings partly"); and it's a little intrusive, adding two services to your PC which are running all the time.
The program does have some time-saving features, though, and a clean and straightforward interface keeps it easy to use. If you're an experienced PC user, looking for a free maintenance suite, then it's worth a closer look.
