Windows: CCleaner, our favourite Windows maintenance tool, just updated to a new version with the added ability to clean up Windows' cluttered right-click menu.
CCleaner's context menu editor is super easy to use: just head to Tools > Startup > Context Menu and find the menu item you want to get rid of. Click on it, and press the Disable button. You can press the Delete button if you choose, but Disabling is a good alternative that lets you bring it back in the future.
The new version of CCleaner also includes Windows 8 support, better support for Opera 12, Firefox Aurora and Chrome Canary, as well as some other bug fixes and minor improvements. For the full list of changes, hit the link below, or just open up CCleaner and check for updates to download the new version.
CCleaner is a free download for Windows only.
