I have a Dell Server that has two drives. The "C" drive as 40 Gig on a Raid 1 and a "D" drive with 650 Gbs open on a Raid 5. The "C" drive is just about used up on space. It is running Server 2008 R2 Standard. The only folder that is really increasing in size is the "Winsxs" under Windows on the "C" drive. It is now over 11 Gb in size and there is only 3 Gb left of open space on the "C" drive. I have been watching this Winsxs folder slowly growing for months. It is loaded with folders that begin with AMD64_xxxxx_xxxxxxx_xxxxx ("x" are different characters). Any idea how to stop this from getting larger and how can I decrease it's size?
