# Acrylic blur radius changer | ||
By default, the Acrylic effect comes with a blur radius of 30, both horizontally and vertically, while not allowing developers or users to modify it. This mod allows the user to modify the default blur radius across **all** apps that utilize the Acrylic effect, by injecting into DWM and hooking all functions necessary to set the aforementioned blur radius. | ||
This will only work on Windows 10, as Windows 11 seems to have changed the functions that make this implementation work. | ||
## ⚠ Important usage note ⚠ | ||
In order to use this mod, you must enable Windhawk to inject into system processes in its advanced settings. | ||
If you do not do this, it will silently fail to inject. **Changing the Windhawk advanced settings will also | ||
affect any other mod you have installed, and may cause instability as any other mod that injects into all | ||
processes will now inject into system processes too.** | ||
This mod will not work on portable versions of Windhawk because DWM is a protected process and can only be | ||
modified by a system account. Since the portable version of Windhawk only runs as administrator under your | ||
own user account, it will not have the privilege required to inject into DWM. | ||
## Examples | ||
