  1. Hello, just yesterday I wondered why my Windows partition is running out of free space while not storing any additional data. I quickly fired up SpaceMonger and searched for space eaters. I quickly identified the C:\Windows\System32\DriverStore to eat up a huge chunk of HD space. What is the Windows driver store? browsing through the files I realised that 80% of the space required was related to stored nVidia drivers. Each version of a driver package took about 150+MB which quickly added up to 1.75GB for storing OLD drivers. Since I am logged in as administrator I decided to just delete those directories. I was unable to do so, because its a SYSTEM folder. If you do a quick google search you will find that you can either take ownership of those directories and delete them the dirty way or you can use a Microsoft tool. pnputil -e PnPUtil lists all the installed 3rd party drivers. e.g. Since my system is already cleaned up I can't show you multiple entries. But the scheme is simple: Each .inf file represents a driver (unordered). It starts at 1 (no preceding zeros) and ends at whatever amount of 3rd party driver you have installed. How can you cleanup those space eaters? Simple! pnputil -d oem<OEMDriverNumber>.inf How should CCleaner support this mechanism? Working with the PNPUtil is a pain. There is absolutely no batch processing or cleanup mechanism. 1. It would be great if CCleaner could support the user by calling PnPUtil with "-e" and parse the resulting list into a data grid, so the user can get a quick overview on which drivers are stored (ideally with size - which is not reported by PnPUtil). 2. Let the user select any number of drivers and send the remove command for those. Note: Unless you specify the "/f" command you can NOT remove driver currently in use and thus affect your system in a negative way. Thanks for CCleaner! Thanks for reading, Mertsch
