How to stop cryptSvc?

Anonymous

I am trying to stop cryptSvc in cmd started as admin:

It refuses to stop displaying this message:

The following services are dependent on the Cryptographic Services service.

Stopping the Cryptographic Services service will also stop these services.

Norton Tools

Norton Antivirus

Smartlocker Filter Driver

Application Identity

I tried to disable Norton Auto-protect as well as Firewall with no change with stop cryptSvc.

You seem to have solved the problem by uninstalling Norton, which looks like the same method I used in the first place.

I find this way easier and more convenient.

Thank you for your response.

Disabling cryptSvc while Norton is running or activated is tricky since Norton Antivirus and Norton Tools are tied to this service.

May I ask would you consider a clean uninstall of Norton?

Here are some ways not to uninstall, but since I have a clean uninstall of Norton on my own computer, I can't do the most accurate test from my own laptop.

Option 1: Disable Norton from startup and reboot.

Open Task Manager (Ctrl + Shift + Esc), go to the “Startup” tab, then “Disable Norton” startup.
Restart your computer and make sure Norton is not running.
Try to stop cryptSvc again. net stop cryptSvc

Option 2: Let's try to enter Safe Mode (Safe Mode without Networking).

You can refer to Safe Mode: Windows startup settings - Microsoft Support

Norton related services can be automatically disabled in safe mode if they are one level below the system level.

Then we will try to disable cryptSvc from the command line.

net stop cryptSvc

Option 3: But I see that when stopping Norton Antivirus, the system prompts

The requested pause, continue or stop is not valid for this service. Is it possible that this signals that Norton has been manually shut down.

So let's try to run the command to shut down cryptSvc directly after shutting down the other services to see what issues are reported or if it shuts down smoothly.

net stop cryptSvc

Answer 4

Thank you for your reply. I temporarily turned off Norton protection and tried first command with following message:

net stop "Norton Antivirus"

The requested pause, continue, or stop is not valid for this service.

Edit: I can stop these two services only:
"Smartlocker Filter Driver" "Application Identity"

Hi Peter Šimkovič

Welcome to Microsoft Community.

Based on your description, I understand that you tried to stop the Norton related servers but were refused to do so, and I understand very well how you feel!

From the information you have provided, it appears that the problem occurs due to the cryptSvc service being bound to another service.

So we need to disable those bound services first, and then disable cryptSvc.

Please note: 1. The above commands are based on the environment of my personal computer, which may have some differences from your computer. If the code does not work properly you need to change the name of the service.

Disabling or stopping the encryption service affects system functionality, especially functionality that relies on Windows security and certificate architecture.

The specific steps are:

Click “Windows Logo Key” to open the search bar -> In the search bar, type “cmd” and open with administrator privileges -> Please enter the following command

You can also use “Windows PowerShell”.

Stop dependent services net stop "Norton Antivirus" net stop "Norton Tools" net stop "Smartlocker Filter Driver" net stop "Application Identity"

If any of these services refuse to stop, make sure they are not running any important tasks or try to disable Norton Antivirus completely from the Norton Antivirus interface.

Below are the disabling steps provided by a Norton official website.

The link is: Unblock safe apps by temporarily turning off your Norton protection

Disclaimer: Microsoft provides no assurances and/or warranties, implied or otherwise, and is not responsible for the information you receive from the third-party linked sites or any support related to technology.

If you have successfully stopped all dependent services, try stopping the cryptSvc service again. net stop cryptSvc
Disable the service If you want to prevent cryptSvc from starting again, do the following sc config cryptSvc start= disabled

I sincerely hope that the above solution will solve your problem. Please feel free to contact me if you have any problems or still can't solve them. (Photos related to the question would be great!) .

I looking forward to hearing back from you.
