CCleaner also provides a startup manager, an uninstaller, and a System restore interface. Also, CCleaner cleans up files that have been created by background processes (like cookies and cache) which users do not manually delete.

Since anyone with access to these files gains immense information about the user, deleting these files is the easiest way to prevent this. As such, CCleaner can assist in getting rid of cache files and browser cookies which store private data. This is hardly a concern nowadays, given that hard disks come cheaper with greater storage capabilities. The first use case this definition brings to mind is freeing up memory from the hard disk. Wise Disk Cleaner is very easy to use and operates in much the same way as any drive cleaner– hit the Scan button for an analysis, then click Clean to remove the listed junk files.CCleaner is a utility program which helps in getting rid of potentially unwanted files and invalid Windows registry entries from a computer. I now find Wise Disk Cleaner to be among the very best, and the fact that there is a portable version available is certainly a huge plus.

However, Wise’s range of freeware has certainly improved since those early days and they have also cleaned up their act– no more bundled potentially unwanted extras. I admit that I haven’t been overly complimentary toward Wise software in the past, especially when they were bundling the awful ”Ask toolbar”. Anyway, I’ve been using Wise Disk Cleaner (portable) as my default drive cleaner for quite some time now, on my own machines and on clients’ machines, and have found it to be extremely safe and effective. I had heard that CCleaner had moved into the dark side since being acquired by Avast but this was the first time I’d witnessed proof of that firsthand. Personally, I haven’t used CCleaner for years and when I downloaded the free portable version for comparison purposes while compiling this article, the very first thing that happened, on the initial run, was a popup advertising the commercial edition… disappointing: That still holds true today and I guess CCleaner’s reputation for safety is what keeps people using it. However, I proved through a series of articles back in 2012 that just about any other free drive cleaner does a better job than CCleaner. For many years CCleaner has been the ubiquitous free drive cleaner, trusted and used by millions of people worldwide.
