You may need to remove a device from a collection because the user may not require that software anymore.
This is written under the assumption you know how to access SCCM.
1. So you go to the collection of the software so in this case: Device collections - software distribution - Adobe
2. Double click the collection you wish to remove the device from
3. Find the device in the collection. If there is a lot of devices then use the search bar
4. Right click the device and remove from collection (DO NOT CLICK DELETE AS THIS WILL REMOVE IT ENTIRELY FROM SCCM)
