So here is my problem. I installed my ages of empires game and tried to run it and it couldn't find the rockalldll.dll (At this point i had about 6gb of space left) and so i was told to run registry booster so i did that and it had many files that needed to be fixed. So i created the backup that it says to do than repaired the registry's. After i did all the my disk space has went to 400mb. Does anyone know why this would be?!!!?? Also i checked the folder winsxs and its about 7 gb of file and 10,926 folders in it. I maybe be thinking if that could be my problem also.
