You should not have even done this. You should have just unplugged the compressor for the winter if that's what you want. AC is used in the winter for humidity control for defrosting.
As far as opening the system, if you open it, or drain it, do not remove anything. If you open it you will need to replace the receiver dryer when you want to turn it back on from moisture contamination.
Why are you doing this procedure?
