Stop a driver from being blocked

Question

Stop a driver from being blocked

Dillon 5

I have a driver that is currently being blocked. It is running a $10,000 laser that is completely useless without the driver. I have turned off all items in Core Isolation and it still will not run. Under device manager it says it is being blocked.

I tried updating the driver it is the newest possible.

It seemed to happen after an update. Why after every update does Microsoft break everything? After an update I have hours and hours of work just to get everything working as it should. This is getting incredibly frustrating especially as I have deadlines I have to meet that unless this item gets fixed fast I will not achieve.

How can I get the driver to work and then use my laser?

Thank you Bulldog for asking if the driver is signed. After looking more and more into everything I finally found the stupid bitlocker code that would allow me to turn off the Driver Signature Enforcement. That after the restart allowed the driver to load properly and now I can continue the work that was suppose to be done already.

Again Thank you Bulldog.

Mainly that because of Windows 11 has increasingly strict driver security requirements (Ongoing effort to optimize the security). Drivers are now used for malicious activities (Be Careful).

I am glad that you able to fix it.

Adding: I advise you to have a more control over the updates since you are using a very critical component.

For this case I was isolate the device to work locally only and use another device for internet access.

I have been using the same driver and machine for around 3 years now. And i have turned off updates so it wont happen again. Also the machine is local and not on the internet. I only use it for internet when I have issues after updating. So now I shouldn't have any more again.
