As you probably nou allready, WS2012, like any Windows, it does not contain a good and reliable disk cleaning application, the one build in is defanatly more then insuficient. My PC is an old one, I have noticed that all previous patches through Windows Update were large and occupied a lot of disk space on C. From what I am aware off, there are only 2 disk cleaning applications compatible with Windows 8, CCleaner and TuneUp Utilities. I allready use CCleaner, it is freeware, it is not enough, altought it helps save a lot of disk space. TuneUp utilities is trial, so it can be used only for a limited period of time. This week some new patches were announced, if they are like the previous ones, very large, this will become a disaster . So I am asking you if you know any realiable disk cleaning applications compatible with Windows 8 and WS2012.
