driver is blocked

Question

After update my driver is not supported. Is this because of Starlink system

Answer 1

Hello

Your question is extremely vague. Which sepcific driver are you referring to?

Answer 2

The driver is blocked because Windows considers it incompatible or insecure, not specifically because of Starlink.

On Windows 11 this usually happens for one of two reasons:

1. The driver is in the Windows Driver Protection database (Device Manager Code 48)
   In this case Device Manager shows:
   “The software for this device has been blocked from starting because it is known to have problems with Windows. Contact the hardware vendor for a new driver. (Code 48)”
   Resolution: obtain an updated driver directly from the hardware/device vendor that supports the current Windows version. If the device is used for Enhanced Sign-in Security, the old driver is blocked because it does not meet security requirements.
2. Memory Integrity (Core isolation) is blocking the driver
   Windows Security → Device Security → Core isolation can block drivers that don’t meet modern security requirements. When that happens you see a notification like “A driver can’t load on this device.”
   Recommended steps:
   • First, check Windows Update and the device manufacturer’s site for a newer, compatible driver.
   • If no compatible driver exists and the device must be used, Memory Integrity can be turned off under Core isolation in Windows Security. This reduces protection and is not recommended unless absolutely necessary.

Starlink itself is not the cause; the underlying reason is that the installed driver does not meet current Windows compatibility or security requirements. The fix is to install a newer driver from the device’s manufacturer, or, as a last resort, temporarily relax security (Memory Integrity) with the associated risk.
