For some reason, ccleaner just randomly stopped erasing my google chrome search history. I even went through the lengths of buying CCleaner pro and it still wont clear the history. Please help me!!!
Pro has no extra ccleaning power (per single user on a pc) when compared to free. However what it does give you is direct and priority email support with the developers.
That said, your question is an often covered issue here on the forum. Does Ccleaner say in the results that chrome was skipped?
If so it could be that chrome (or a chrome based application) is still running. This is usually caused by chrome either running in a window or if you have background chrome services turned on (cloud print, background sync). If after turning background services off and exiting chrome via file/exit the problem persists, check Windows task manager details/processes tab for chrome.exe
