CCleaner hangs when cleaning IE history in CCleaner Bug Reporting Posted August 14, 2009 DennisD, Thanks for the reply and suggestion. Yes, it was from a recent Microsoft update, and uninstalling it solved the problem. CCleaner cleans IE History quickly without Windows Search installed. The "hang" reoccurs after reinstalling Windows Search. I hate to give it up because it is so quick, thorough, and a huge improvement over the standard search engine in XP. I wonder if it is just something peculiar with my machine since I cannot find any other references to the issue in the forum. I normally use Firefox, so I may just uncheck the IE History box in CCleaner so I can keep Windows Search installed. Thanks again! Hi fastcolts, and welcome to Piriform. Was that "Windows Search" part of a recent update from Microsoft? Maybe uninstall it and see if it actually is the problem. You would need to check the "Show Updates" box in Add/Remove programs to do so. EDIT: It probably starts with Windows if it's from MS. I can't check as I passed on that update.
