This article explains how to turn Dev Drive Protection On or Off in Windows 11.
Dev Drive is a new form of storage volume available to improve performance for key developer workloads. It is built on ReFS technology to employ targeted file system optimizations and provide more control over storage volume settings and security.
By default, Dev Drive is created for the best performance and automatically grants trust in the new volume to support antivirus configuration and administrative control over what filters are attached.
There are two performance modes one can use with Dev Drive. The following table summarizes performance mode synchronous and asynchronous scan behavior.
|PERFORMANCE MODE STATE
|Not enabled (Off)
|Opening a file initiates a Real-time protection scan.
|Open now, scan now.
|File open operations are scanned asynchronously.
|Open now, scan later.
For more on Dev Drive performance and considerations, read the post below.
Starting with Windows 11 build 25931, you can turn the performance mode for Dev Drive protection on or off in the Windows Security app.
Enable or disable Dev Drive Protection in Windows
Here’s how to do that.
First, open the Windows Security app.
You can do that by clicking on the Start menu and searching for “Windows Security.” Then, under Best match, click on the Windows Security app.
In the Windows Security app, on the “Security at a glance page,” click the Virus & threat protection link on the left menu or the main window pane.
Virus & threat protection settings page, click the Manage settings link.
On the Virtus & threat protection settings page, under Dev Drive protection, toggle the switch to the On position to enable.
To disable it, toggle the switch to the Off position.
If you don’t have Real-time protection turned on, Dev Drive protection will be grayed out.
Save your changes and exit the Windows Security app.
Enable or disable Dev Drive protection using the Registry Editor
Using the Registry Editor is another way to turn on or off Dev Drive protection.
To do that, open the Windows Registry editor and navigate to the folder key below.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Real-Time Protection
If you don’t see the
Real-Time Protection folder key, right-click on the
Windows Defender parent key, then create the subkey (Real-Time Protection) folder.
Right-click the Edge folder key’s right pane and select New > DWORD (32-bit) Value. Type a new item named DisableAsyncScanOnOpen.
Double-click the new item you created (DisableAsyncScanOnOpen) and update the Value data:
- To turn on Dev Drive protection, type 0.
- To turn off Dev Drive protection, type 1.
That should do it!
