CCAuto updater is a free tool to automatically update CCleaner. With this tool you never have to download and install the new versions, CCAuto updater will do it for you. You can either run it manually, on schedule, or on start up.
After CCAuto Updater has updated CCleaner it will let you know with a small balloontip message or prompt.
CCAuto Updater also has the option to run CCleaner scheduled without any UAC (User account control) prompts. Another advantage of using CCAuto Updater is that the "Yahoo! Toolbar" won't be installed in the updating process.

How does it work?
1. Download and extract the CCAuto Updater zip file.
2. Run cc_update.exe. It should automatically prompt you for Administrator Rights if you have UAC enabled. In case UAC is enabled and you do not get a promopt, start the program and by rightclicking on the CCAuto Updater icon and choose the option "Run as administrator".
3. Click on "Browse" and select the direcory where you installed CCleaner. CCAuto Updater will now gather all the information of your currently installed version of CCleaner.
4. For manual update click "Update CCleaner". For scheduled updating use the checkboxes on the bottom.
