They are an essential part of the Nation's defense.
Most castles started out as a motte and bailey. A mont and bailey is a wooden structure built on a higher hill in the area. It had a wooden wall around it and inside would be a main house/structure, barns, and areas for animals. When gun power was introduced to Europe this had to change so they changed the wooden walls to stone. Actually it was a faux wall. They left the wooden part and added stone in front of it. They made walls with a stone front and between the wooden wall and the stone wall they put in the bits and pieces of the construction mateials as a filler so that it looked solid. William the Conqueror changed castles forever. He built stone towers that were hard to attack and could be defended From the stone towers came the shapes we know of castles. Castles became status symbols and a show of power and money as well as for defense

Glass production has been around for 3000 years but they were not incorporated into early castles for one obvious reason. They offer no military defense and castles were military installations. So its unlikely that windows were added till after the period that castles were strategically important. THis would have probably been during the Elizabethan/Tudor period when castles became more like stately homes than defensible miltary installations. Probably the only place you would have found glasing in a medieval Castle would have been the chapel which may have had a stained glass window in it. Of course castles could have been retrofitted with glass but few were built with it as part of the original design.
No. They are part of the state department.
A keep is a very important part of a medieval castle. It is the castles finial defence from attackers.
