 Hi tj_zero, Thanks for your post. There are two options to disable the use of USB storage devices on Windows 10 computer. Option 1: Disable/restrict access to USB storage devices by Group Policy Editor Step 1: Open Local Group Policy Editor in Windows 10 by running gpedit.msc in Run (Win + R) dialog box. Type gpedit.msc in Run box Step 2: Expand Computer Configuration > Administrative Templates > System, and select Removable Storage Access. On the right-side pane, locate ''Removable Disks: Deny execute access'', ''Removable Disks: Deny read access'', and ''Removable Disks: Deny write access''. Double-click on each of them to configure it. Restrict acess to removable disks Step 3: Select Enabled, then click Apply and click OK. This will disable execute, read, and write access to any removable disks including USB storage devices connected to the computer. If you want to enable the use of USB storage devices, set it to ''Not configured'' or ''Disabled''. Select Enabled Option 2: Disable the use of USB storage devices by Registry Editor Step 1: Open Registry Editor in Windows 10 by running regedit in the Run dialog box. Type regedit in Run box Step 2: Go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR, and then locate the DWORD value named ''Start'' on the right-side pane. The default value data of Start is ''3''. Double-click on Start, and set its value data to ''4''. Change value data Step 3: Restart Windows 10 for the changes to take effect. This will prevent any USB storage device from connecting to the computer, and thus disable the use of USB storage devices on the computer. Note: By Registry Editor, you just disable the use of USB storage devices, but it won't affect the use of USB mouse, keyboard, and printer on the computer. Best Regards, Ian Xue
