Uninstalling Roblox from Teacher's Laptop.

[Koldov]

I have found an installation of Roblox but can't seem to find a way to uninstall it cleanly.

 

If I log on as Admin it doesn't show at all, not in uninstall from Programs and Features or in any menu, as it's installed in the user's Appdata.

 

If I log on as the user I can see it to uninstall, but it wants to go to the Roblox servers and as it is blocked it won't continue.

 

I also can't see if there are any services running under the user as that function is blocked.

 

Is it worth unblocking Roblox from the filtering to uninstall with the application uninstaller or just delete everything I can find in folders and registry relating to it?

Would just unfilter that laptop while you unblock it , then add an applocker restriction to prevent installation again

Is it installed as a Chrome app?

Is it installed as a Chrome app?

 

No, I don't believe so. It doesn't show in Chrome's Apps.

 

It shows up as Roblox Player and Roblox Studio in the user's start/programs menu.

Windows Store App?

Windows Store App?

 

I don't think that's possible (laptop is runinng LTSB)?

If you wipe their local profile, that'll delete it.

Well, I've 'uninstalled' it, but it has still left masses of folders and files to manually delete anyway.

 

add an applocker restriction to prevent installation again

 

Has anybody got a dummies guide for adding an applocker restriction for just one app?

 

I am trying to work out SRP and Applocker restrictions on a wider scale, but I need to give this laptop back today and I don't want it installed again!

 

If you wipe their local profile, that'll delete it.

 

Hmmmm, yes.... that will certainly delete it and their life's work that's sitting on the desktop... (don't get me started) but thanks for the help anyway!

NCSC recommend using an AppLocker allow list (whitelist) to control which applications can run, and have a set of policies at https://www.ncsc.gov.uk/collection/end-user-device-security/platform-specific-guidance/eud-security-guidance-windows-10-1809#applockerconfig

 

They have some more recent guidance, but it’s not as detailed. You can, however, download a set of GPOs to review.

 

If you just want to block Roblox, hopefully it’s digitally signed, in which case you can create a publisher rule to block it. If it’s not digitally signed, you’ll probably need to add a path or hash rule, which may end up being like whack-a-mole in terms of blocking it.
