Block access to removable media data carriers under Windows!
Configure access to all removable drives on all Windows 11, 10, ... operating systems!
Many users and administrators do not want external USB sticks, SD cards, etc. to be connected to the Windows computer in order to ensure more security on the operating system. This can be achieved under all Windows operating systems via two Windows registry entries. And thus prevent any unwanted software from being installed.
1.) Block access to all removable media via registry!
Open the key in the Windows Registry:
Currently logged in user:
For all users on the Windows computer:
and simply create a REG_DWORD, "Deny_All" and set the value to: 1
If you want to allow access to external drives again, then to 0 (NULL), or simply delete the "Deny_All" entry
(... see Image-1 Point 1 and 2)

Path: Administrative Templates ►System ► Removable Storage Access
Setting: All removable Storage classes: Deny all access activate
Tip: ► Force update on local group policy changes!

If you enable this policy setting, all access to removable storage classes is denied.
If you disable or do not configure this policy setting, read and write access to all removable media classes is allowed.
