Restrict Access To Drives

You may not want other users of your computer having access to certain data on your machine.

Protecting Your Files from Other Users

[1] By Changing Drive Properties
This guide will show you how to deny access to other user accounts; you can also easily do things like give certain users read-only access (they cannot edit or delete files you protect) if you need to.
Do the following:
Right click on the drive, folder, or file you want to protect (never choose the entire C drive) and select Properties


Select the Security tab and click Edit…

Now click Add…

Type the user’s login name and click OK

Select Deny next to Full control (Alternatively you can customize permissions here)

The files permissions will now be updated. This may take some time.





Now login as the user to test the permissions; the drive/folder/file should not be accessible

Double clicking on the file should produce a similar error to the one above!


[2] By Change In Registry

1. Open regedit.exe from run
2.Scroll down for the following registry key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

3. In the right side pane, create a new DWORD value, ‘NoViewOnDrive’ & set its data value to the drive that you want to hise as per the below list:
A:1 B:2 C:4 D:8 E:16 F:32 G:64 H:128
ALL:67108863

Its also possible to implement the above by simply creating & executing a file with a .reg extension containing the below data:

REGEDIT4 [ Name & Version of your Registry]
[ Choose Registry Key From Key]
“NoViewOnDrive”=”Drive Number”
OR

1. Scroll Down to following in registry
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR



2. Modify 'Start' Dword to "4" to disable USB DRIVE
3. Set it to "3" to Enable Usb Drive Again.

[3] By Disabling Device From Device Manager

1. Right Click on 'My Computer' / Manage.




2. Click on Device Manager, under System Tools Tab.

3.You will see List of Hardware devices, Find 'Universal Serial Bus Controllers'.
