![]() The vast majority of the fixes only need to be performed once, and having them as the default option can slow your computer down and increase the risk of you erasing something you didn’t mean to. Secondly, only select the advanced options once you’ve decided to use them and then uncheck them when you’ve finished – don’t leave them ticked. So what’s the final verdict? The first step is to make sure you know what an option does before you choose it. It’s in Advanced, however, because it can take really long time to complete some online accounts even point to 6 hours or more! Wipe Free Space works by overwriting these areas of your disk, thus making it much harder to extract data about deleted files. You can wipe only free space or the entire drive, and you can choose up to 35 passes, meaning data will be. In other words, deleting a file doesn’t get rid of all its data, it just says ‘this space can now be considered free’. Open CCleaner and go to > Tools > Drive Wiper. When you delete files from your disk, much of the space they occupied retains data from those files but is effectively re-allocated as ‘free’ space. This feature is for anyone interested in security. If you are confident that the hotfix they refer to is ok, there’s no real need for the uninstaller. The uninstallers exist in case you install a patch that causes problems and you need to remove it. Hotfix Uninstallers – hotfixes are also known as patches. Like many log files, theses are not something that the average user is very interested in, but they can be useful for bug fixing. It’s a Microsoft service for Windows users’ internet services. IIS Log Files – IIS stands for Internet Information Services. Clearing it accidentally can be irritating, but not fatal. User Assist History – this will clear recently-used programs from the Start Menu. If you have any special set-up, it will be reset. Tray Notifications Cache – again, where Windows stores information about the items that appear or have appeared in the Tray Menu. As CCleaner warns, any custom preferences will be reset, although nothing will actually be removed. Menu Order Cache – this is where Windows stores information about the items that appear or have appeared in your Start menu. Nobody seems to be able to agree, so this one is completely in your own hands. Others argue that Windows deletes them automatically, so there is no need. Some people argue that over time the function becomes overcrowded, hence the need to delete. Pre-fetch files are basically parts of programs that Windows caches (‘pre-fetches’) so they are easily accessible when needed. Old Prefetch Data – this is actually a controversial option. Bearing this in mind, let’s go through what some of these Advanced bits actually do. ![]() These options are precisely the tools that could do some serious damage to your system if used wrongly. I’ll say it again, while CCleaner will positively shout it – don’t use the Advanced options unless you are very, very sure that you know what you are doing.
