DelProf2 1.6.0 was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this software available. The most popular versions among the software users are 1.6 and 1.0. The software lies within System Utilities, more precisely System Optimization. We recommend checking the downloaded files with any free antivirus. The actual developer of the free program is Helge Klein.
From the developer:
Delprof2 is the unofficial successor to Microsoft Delprof which does not work with operating systems newer than Windows XP.
Delprof2 deletes inactive user profiles. If you want to reclaim disk space just run it without parameters and it will delete all profiles except your own and some special profiles needed by the operating system (like “Default”).
You may want to check out more software, such as TweakXP Tweaking Utility, UpdateScanner or ResChanger 2005, which might be similar to DelProf2.
