Let’s assume that as an IT administrator, you deployed a configuration profile via Intune to prevent users from connecting USB devices to their computers. Everything works very well, and you’re quite satisfied with your setup. Then one day, you urgently need to copy a file from one of these computers. You don’t have Internet access to send the data via an online storage solution (OneDrive, Google Drive, etc.). On the other hand, you do have a USB device to hand. As you can see, you need a way to bypass the security set up above. In this blog post, I’ll show you how.

Resolution

You need to edit the following two registry keys below:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PolicyManager\current\device\System

Name: AllowStorageCard
Type: DWORD
Value: 0 for block, 1 for allow

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\StorageSense\Parameters

Name: StorageCardDisabled
Type: DWORD
Value: 0 for allow, 1 for block

Now you can connect the USB stick, and you’re ready to go!

Alternatively, You can wrap all this as PowerShell script and run it:

function change-registry([string]$reg, [string]$name, [int]$value) {
try
{
Set-ItemProperty -Path $reg -Name $name -Value $value -Type DWord -ErrorAction Stop
}
catch
{
New-Item -Path $reg -Force
New-ItemProperty -Path $reg -Name $name -Value $value -Type DWord
}
}

change-registry -reg "HKLM:\Software\Microsoft\Windows\CurrentVersion\StorageSense\Parameters" -name "StorageCardDisabled" -value 0
change-registry -reg "HKLM:\Software\Microsoft\PolicyManager\Current\Device\System" -name "AllowStorageCard" -value 1
