IObit Toolbox contains a selection of useful maintenance tools for your PC. It's lightweight and doesn't need to be installed, so you can run it directly from a USB stick.

The main interface in IObit Toolbox is bold and easy to understand, with the tools organized into four categories, Clean, Optimize, Repair, Security and Control. Inside each of IObit Toolbox's categories are a set of tools. There's a lot here, from a registry cleaner and privacy sweeper to a startup manager and disk explorer.

Some of IObit Toolbox's functions replicate what's available in Windows, like System Control, but the presentation is different and arguably nicer to look at and better organized. One of the most useful tools is perhaps the file recovery tool - even if you've emptied the recycle bin, there's a good chance you can get your file back with Undelete.

Overall, IObit Toolbox is a really useful collection of applications that will be very useful to keep on a portable drive, ready to fix whatever iss going wrong with your PC.
