I checked CCleaner Free Portable v5.83 and as I reported <here> for v5.82, there's no Driver Updater feature bundled inside ccsetup583.zip (i.e., no CCleanerDU.dll file and no Driver Updater on the main interface). Given all the serious bugs reported for this new feature at https://community.ccleaner.com/forum/46-driver-updater/ I'm personally happy to see it's not going to be included in the Portable version. I suspect Driver Updater was deliberately omitted because the Portable version is not installed into Windows like "traditional" software and will run from a removable USB thumb drive on multiple machines with different hardware configurations.
