It’s that time of the month when Piriform’s team delivers their regular CCleaner update, and sure enough they’ve announced the availability of CCleaner 4.19 and CCleaner 4.19 Portable.

The big news this time is compatibility with Windows 10 Technical Preview. If you’re using the new system so much that it’s cluttered with junk, then the program can now give it a thorough cleanup, just like any other.

Improved application support sees the program do a better job of cleaning the Opera 25 cache.

There’s more reliable automatic update checking.

We can’t remember the last time CCleaner displayed an error message for us, but if major problems do strike then version 4.19 brings improved exception handling and reporting.

There are also the usual collection of non-specific translation and interface tweaks, along with a scattering of minor bug fixes.

CCleaner 4.19 and CCleaner 4.19 Portable are available now as freeware downloads for Windows XP and later.
