I'm looking for a way to disable Copilot throughout our organization because we're using a different LLM. I've searched for solutions but haven't found anything effective. I came across some documentation that doesn't seem to work. If anyone has advice on how to disable Copilot for all users, I'd really appreciate it! Thanks!

First off, you need to clarify which Copilot you're referring to because Microsoft has so many versions with similar names! But I'd suggest using AppLocker via Group Policy to disable the packaged app. Specifically, you can block 'Microsoft.Copilot' and 'Microsoft.MicrosoftOfficeHub'. That's what I did in my own domain, and it worked perfectly! Just make sure to add the default 'allow' rules; otherwise, you might end up blocking essential apps, like I accidentally did with the calculator! Haha!
Yeah, same here! The combination of AppLocker and the right policies killed the issues we were facing. Make sure to test thoroughly to avoid accidentally blocking useful apps.
I totally feel you on this! We're also having Copilot pop up everywhere despite taking the advice to turn it off. It's pretty frustrating! Any luck on your end since you posted?
If you're running Windows 11, I found a PowerShell script to disable Windows Copilot by tweaking registry settings. Just be careful, as it’s quite a hands-on approach. You create specific registry keys to turn it off, and it even accounts for default user setups. However, some of these methods have been deprecated lately, so always check current documentation before trying it out!
That's useful info! But heads up, I tried a similar script earlier this year, and it didn't work because Microsoft changed some settings. Always good to verify those registry paths!

For sure! We also had to use PDQ to remove Copilot from all PCs to prevent users from clicking on it, which just led to error messages. We kept M365 Copilot active for testing, but AppLocker worked wonders for our main issue.
