I am using Windows Vista Home Premium 32-bit with CCleaner v2.06.567 and have a few additional features for the program to clean:
WINDOWS ERROR REPORTING
FileKey1=%allusersprofile%\Microsoft\Windows\WER\ReportArchive|*.*|RECURSE
FileKey2=%allusersprofile%\Microsoft\Windows\WER\ReportQueue|*.*|RECURSE
FileKey3=%localappdata%\Microsoft\Windows\WER\ReportArchive|*.*|RECURSE
FileKey4=%localappdata%\Microsoft\Windows\WER\ReportQueue|*.*|RECURSE
The Disk Cleanup utility built into Vista cleans these files but is very slow at doing so.
PERFORMANCE AND RELIABILITY MONITOR
FileKey1=%programdata%\Microsoft\RAC\PublishedData|*.*
FileKey2=%programdata%\Microsoft\RAC\StateData|*.*
Upon deleting these report logs, Windows Vista may take around 24 hours to generate new reports again.
WINDOWS INSTALLER
FileKey1=%systemdrive%\Config.Msi|*.*|REMOVESELF
Windows Installer (.msi) files create this folder in the root directory of the partition on which they are run. The files within this folder are usually deleted once the installation has completed, but the folder itself remains orphaned.
CRYPTNET CACHE
FileKey1=%userprofile%\AppData\LocalLow\Microsoft\CryptnetUrlCache\Content|*.*
FileKey2=%userprofile%\AppData\LocalLow\Microsoft\CryptnetUrlCache\MetaData|*.*
The files in these folders can build up significantly within a short space of time and can be safely deleted. They will be regenerated as and when required.
GENERAL LOGS
FileKey1=%windir%\Logs\CBS|*.log
FileKey2=%windir%\Logs\DPX|*.log
FileKey3=%windir%\Logs\WindowsBackup|*.etl
SYSTEM ASSESSMENT TOOL
FileKey1=%windir%\Performance\WinSAT|winsat.log
This file is created after running the System Assessment Tool from the "Performance Information and Tools" Control Panel. Also in this folder is a DataStore folder containing XML files with filenames that begin with the dates the tool was run. All but the most recently dated file can be deleted.
FOLDER VIEW SETTINGS
RegKey1=HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\BagMRU
RegKey2=HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags
RegKey3=HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\MuiCache
RegKey4=HKCU\Software\Microsoft\Windows\Shell\BagMRU
RegKey5=HKCU\Software\Microsoft\Windows\Shell\Bags
These keys contain stored folder view settings such as details, tiles, and large icons view. To reset folder views back to their defaults, these keys can be deleted and will be regenerated automatically when required. Previously, these settings appear to have been included in CCleaner, but I have not seen any similar functionality in more recent builds.
PROGRAMS AND FEATURES CONTROL PANEL
RegKey1=HKCU\Software\Microsoft\Windows\CurrentVersion\App Management\ARPCache
This registry key speeds up the display of the list of programs in the "Programs and Features" (or "Add/Remove Programs") Control Panel. After uninstalling a program, the cache entries are typically not removed from this location. The ARPCache key is automatically recreated (without the previously orphaned entries) when you open the "Programs and Features" Control Panel again.
