Are you really necessary? Say on a scale of 1-10?
Because I feel like you occur really frequently which makes me think one of the following:
a) The software I originally purchased is faulty.
b) You want to take up space on my hard drive causing me to run out of room, leaving me with the only option of buying an external hard drive so I have more storage capacity that will only end up being consumed by more Microsoft updates.
c) I'm a nerd for even caring about this at 12:19 in the morning.
