How to erase U disk use record?

Open the Control Panel-> Management tool-> Computer Management to see if Removable Storage has a lot of USB records ah?

See how to remove it:

1. Add the environment variable devmgr_shownonpresent_devices to the system, the value is 1

2. Run Device Manager to open the view hidden device. Expand the disk drive, storage Volume two, and the U disk related

Kill off.

3. Turn on Computer Management to delete Removable Storage related.

4. Delete the system environment variables added to the 1.

So far, it may not be possible to delete all the USB usage records in the registry at hkey_local_machine/

There may still be a use record in the System/controlset002/enum/usbstor, and then open the mighty REGEDT3

2 tool, locate the item, modify the permissions, and then delete the subkey. In addition Hkey_local_machine/system/control

Some of the SET002/ENUM/USB associated with USB Storage mass devices are also deleted.

Clear the registry USB disk usage record

1, press the start--〉 Run, enter the command in the input box: regedit

2. Delete the Usbstor subkey of the following directory in the registry.

(1) Hkey_local_machine/system/controlset001/enum/usbstor

(2) Hkey_local_machine/system/controlset002/enum/usbstor

(3) Hkey_local_machine/system/controlset003/enum/usbstor

(4) Hkey_local_machine/system/currentcontrolset/enum/usbstor

After deleting the Usbstor subkey, the general confidential inspection software cannot be checked.

If you need to completely erase the USB usage records, after doing this, you can proceed to the following procedure:

1, delete the following USB subkey except Root_hub, Root_hub20 all records.

(1) Hkey_local_machine/system/controlset001/enum//usb

(2) Hkey_local_machine/system/controlset002/enum/usb

(3) Hkey_local_machine/system/controlset003/enum/usb

(4) Hkey_local_machine/system/currentcontrolset/enum/usb

Permission actions are consistent with the above operation.

2, delete the deviceclasses under the a5d ..., 53f ... And so on with the USB word part of the subkey.

(1) Hkey_local_machine/system/controlset001/control/deviceclasses/{a5dcbf10-6530-11d2-901f-00c04fb951ed}

(2) Hkey_local_machine/system/controlset002/control/deviceclasses/{a5dcbf10-6530-11d2-901f-00c04fb951ed}

(3) Hkey_local_machine/system/controlset003/control/deviceclasses/{a5dcbf10-6530-11d2-901f-00c04fb951ed}

(4) hkey_local_machine/system/controlset001/control/deviceclasses/{53f56307-b6bf-11d0-94f2-00a0c91efb8b}##?# usbstor#disk&ven_alcor&prod_flash_disk&rev_8.07#2624bfbb&0#{ 53F56307-B6BF-11D0-94F2-00A0C91EFB8B}

......

The other actions are the same as the previous step.

Finally, another place is important, the Windows system generated log files

The log for C:/windows/setupapi.log, the log recorded the use of U Disk Time and U disk manufacturers and so on information.
