As long as you do not get the same updates all over again, there is nothing to worryx about.
The updates come in a certain sequence as they had been originally released. Sometimes updates can only be installed when previous updates have already been done.
I recently reinstalled a Win7 on a friends system and had to deal with over 260 updates. The process took 3 days - and that only because I kept looking for them. Else it would have been even longer.
