You can change the folder for updates!
1: create a target directory
for example :
D:\other\desired\location
2:Ctrl+alt+delete>taskmanager>services>(right click on) wuauserv (then choose stop)
3:rename c:\windows\softwaredistribution
this folder to softwaredistribution.old
4:Run cmd as administrator and type this command then hit enter
mklink /j c:\windows\softwaredistribution d:\other\desired\location
("d:\other\desired\location" u can type another location that existed on your hard drive or you can create in step 1 )
5:type this command on Cmd and then hit enter
net start wuauserv
Or you can manually start service like step 2 !
6: if everything was ok
you can move softwaredistribution.old files in new directory in the new drive
Then it will work
