Three ways to teach you to delete a U disk use footprint

Scenario One: Manually delete registry information.

㈠, first add environment variable "devmgr_shownonpresent_devices" value to "1" in the system

㈡, open Device Manager, then look at the hidden device, expand the disk drive and storage Volume two, and then remove the USB stick.

㈢, mouse click "My Computer" right to select "Admin" to open, and then delete the information related to removable Storage.

㈣, delete the system environment variable "devmgr_shownonpresent_devices" added to "㈠".

㈤, open the registry (enter "Regedit" in the Start Menu "run" input box to open the registry directly), after the registry opens, click Edit-Find, and then enter "Usbstor" in the input box to check only "items" and not select "value" and "data" (can speed up the search) , click "OK" or press ENTER to start the search, will search for "usbstor" items, and then all delete (each delete one of the time to press "F3"), if some can not be deleted, click the right mouse button select "Permission" to enter the permission settings, select "Allow"-"full Control" can be. If not, we can in the registry to select the mouse on the registry "My Computer", and then press "F3" and then query delete again.

Here we enumerate the details of the registry that need to be deleted: Delete the registry Usbstor subkey for the following directory.

⑴hkey_local_machine/system/controlset001/enum/usbstor

⑵hkey_local_machine/system/controlset002/enum/usbstor

⑶hkey_local_machine/system/controlset003/enum/usbstor

⑷hkey_local_machine/system/currentcontrolset/enum/usbstor

Delete the above Usbstor subkey, the general confidential inspection software can not check out the use of the U disk record.

If you need to completely erase the U disk usage record, after completing the above operation, we will continue to operate:

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

⑴hkey_local_machine/system/controlset001/enum/usb

⑵hkey_local_machine/system/controlset002/enum/usb

⑶hkey_local_machine/system/controlset003/enum/usb

⑷hkey_local_machine/system/currentcontrolset/enum/usb

The operation to remove permission restrictions is consistent with the above operation.

2, delete the deviceclasses under the a5d ..., 53f ... such as a partial subkey that contains a USB character.

⑴hkey_local_machine/system/controlset001/control/deviceclasses/{a5dcbf10-6530-11d2-901f-00c04fb951ed}

⑵hkey_local_machine/system/controlset002/control/deviceclasses/{a5dcbf10-6530-11d2-901f-00c04fb951ed}

⑶hkey_local_machine/system/controlset003/control/deviceclasses/{a5dcbf10-6530-11d2-901f-00c04fb951ed}

⑷hkey_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}

......

⑸hkey_local_machine/system/currentcontrolset/control/deviceclasses/{a5dcbf10-6530-11d2-901f-00c04fb951ed}

The other actions are the same as the previous step.

Plan two: Use related cleaning tools to clean u disk using records.

Cleaning up the U disk use record software is more common is the "usbviewer" tool, you can go to the Internet to search and download. Specific methods of use can also be found online.

Using the "usbviewer" tool to remove the use of the U disk sometimes can not be completely cleared of the situation, especially in the strict confidentiality of units, inspectors will be involved in the secret of the machine to carry out in-depth inspection, at this time the defects of the usbviewer exposed, because the mobile media plug record did not clear clean.

Plan three: The most effective way is to lower the level of the PC format, but it is more troublesome oh.

If your computer applications are small and use less space, and the reload system does not affect your normal work, this method is still possible. However, if your system installs a lot of scientific computing software (such as AutoCAD, FEM modeling simulation software, image processing software, professional development design software), the disk format is still more trouble.

Sometimes in order to be safe, we have to delete the U disk in the use of computer records, read the above introduction, you can choose a program to protect their privacy, and so what? Go ahead and try it.
