I.E. cache deleted upon reboot

After installing CCleaner and thereafter rebooting my internet cache was deleted when entering desktop. Is this an automatic function within CCleaner? If so I would like to turn it off.

Thanks

By default, Ccleaner settings are set to what most users want to get rid of. However you can uncheck any objects you want Ccleaner to leave alone.

Internet cache is either Internet Explorer "Temporary Internet Files" and Index.dat files (Windows tab), or whatever browser you use on the Applications tab.

If you want to keep cookies, uncheck Cookies in the same sections, or better, go to Options -> Cookies, and move the cookies you want to keep from the left side to the right. Next time you run Ccleaner with Cookies checked, the ones you moved to the right will be kept.
