DeviceCleanup V0.7.1.0 - Removes non-present devices from the Windows device management
Freeware by Uwe Sieber - www.uwe-sieber.de
Works under Window 2000, XP and higher
On x64 Windows only the x64 release can delete devices.
All devices listed by DeviceCleanup are currently not present, usually they have the problem
code 45 which is CM_PROB_PHANTOM, "The devinst currently exists only in the registry".
You can select one, multiple or all devices and remove them. If the device is attached again
it will be detected as new.
The 'last used' time comes from the write time of the device's registry key
under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum
On some Windows the times are set on startup or even while it is running every few hours,
so all devices seem to have the same age. On a Windows 7 the Sysinternal ProcessMonitor
shows a recurring RegSetKeySecurity caused by a svchost.exe hosting the PlugPlay service
every 11 hours 45 minutes. No idea what is causing it. I you want to check yourself:
Set a filter "operation is RegSetKeySecurity" and set the option "Filter -> Drop filtered
events", otherwise your pagefile (or other backing file) gets flooded in no time.
On most Windows the time is set when the device gets active, so it makes sense to use this as
'last used' time.
Non-PnP devices and 'soft' devices are not listed because they are not automatically reinstalled.
These are devices whose ID begins with
- HTREE\ROOT\
- ROOT\
- SW\{
If you want to delete them, use the Windows Device Manager.
For removing devices admin privileges are required, otherwise you get an access denied error.
Since regular device management functions are used, any removed device's CoInstallers are called
as planned, so you might loose for instance custom Explorer icons for card reader volumes. Just
have the card reader attached while executing DriveCleanup to prevent this.
A command line version is available too:

DriveCleanup V1.5.0 - removes non present drives from the device tree
Freeware by Uwe Sieber (c) 2007-2017
Works under Windows XP and higher only. Under x64 edtitions of Windows
only the x64 version works.
Removes from the device tree non present
- USB hubs
- USB mass storage devices
- USB Disk devices
- USB CDROM devices
- USB Floppy devices
- USB Storage Volumes
- USB WPD devices (Vista, Win7, Win8, Win10)
and their registry items under
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\UsbFlags
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EMDMgmt
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2\CPC\Volume
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\BitBucket\Volume
Usage:
DriveCleanup [-t] [-n] [-u] [-d] [-c] [-f] [-v] [-r]
no params: cleanup all
-t test mode
-n no wait for keypress when finished if started standalone
-u only USB mass storage devices
-d only USB Disk devices
-c only USB CDROM devices
-f only USB Floppy devices
-v only USB Storage Volume devices
-r only registry items of USB volumes
-w only USB WPD devices
Called with admin previleges and without a parameter it removes all types of devices
listed above and cleans the registry.
Without admin previleges it switches to test mode and shows the items it would remove.
Samples:
DriveCleanup -t
test mode, lists devices and registry items to remove
DriveCleanup
removes non present devices related to drives and their registry items
DriveCleanup -v -d
removes non present USB Storage Volumes and USB Disks
Administrator previleges are required for cleanup.
DriveCleanup isn't stricly limited to drives. USB hubs and the Enum\NextParentID.xxxxx.n
values may be not drive related.
Deleteing automatically any type of non-present device seems to be too dangerous, therefore
I've made a GUI tool for this, so it's up to the user not to delete something important...
http://www.uwe-sieber.de/misc_tool_e.html#devicecleanup
DriveCleanup calls Windows device manangement functions for deleting devices entries. If it shows OK
then Windows responded that this succeeded. When finished DriveCleanup checks all again and should
find zero devices if it showed OK for all before. Sometimes Windows says OK but in fact the device
is still present.
Since regular device management functions are used, any removed device's CoInstallers are called
as planned, so you might loose for instance custom Explorer icons for card reader volumes. Just
have the card reader attached while executing DriveCleanup to prevent this.
Starting with Vista Administrators have no more write access to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum
and even being the owner they have no right to change the permissions. Therefore deleting unreferenced
NextParentID.xxxxx.n items needs more than admin previleges. To get these, DriveCleanup steals the access
token of a system process and impersonates its context to change Enum's security descriptor, then performs the
cleanup and restores the security descriptor. Maybe this alerts security software.
Since V1.4 volumes of the Windows volume shadow copy facility are't skipped anymore. Before they where skipped
because I wasn't sure if it is ok to delete them. Since Microsoft offers it's own tool to do so, I is ok
