Here are all the files bundled inside the Portable ccsetup582.zip ( note that I normally delete all files but CCleaner64.exe, Portable.dat and License.txt and copy over the CCleaner.ini configuration file from the previous version):Īccording to the version history at the addition of a fully functional Driver Updater to CCleaner Pro v5.82 (i.e., that can both detect and install driver updates) is the only change that was made in this release - there are no bug fixes so I think I'll be skipping v5.82 altogether.

Simply excluding all Intel network cards from the driver scan seems like a quick and dirty way to solve the problem, and it makes me wonder how many other outdated drivers are being recommended (and automatically installed) by Driver Updater in CCleaner Pro.Īs a general rule most third-party driver updater and registry cleaner utilities are detected by Malwarebytes as PUPs (potentially unwanted programs). This has been corrected, so that such driver updates for Intel network cards should no longer be offered as of tomorrow morning. According to employee Ezra CCleaner's post today (1) in Two Issues with Driver UpdaterDriver Updater will be 'fixed' so that it no longer looks for driver updates for Intel network cards.įor the point 1 It's detecting an older version as if it's newer (see screenshot). I've seen reports where the new Driver Updater feature in CCleaner v5.82 is offering outdated drivers for Intel network cards that are older than the installed version.
