SBS2011 out of disk space

Question

Scenario:

SO: SBS2011 - HD: 186GB - Available space: 0

• The Exchange and Sharepoint databases are stored on a different drive,
• Users data are saved on a different drive

DIRs and file greater than 1GB:

• /windows/winsxs -> 45,5GB
• /windows/installer -> 5,5GB
• /windows/assembly -> 2,5GB
• /unknown -> 113,9 GB (this file is shown by windir only)

I tried:

1) Disk cleaner, the tool claim to be able cleaning 18Gb of system file, but once started and run for some minutes it stops with no message.

2) dism /online /cleanup-image /spsuperseded with no success

I already cleaned all temporary dirs and deleted all unused accounts getting 200MB of free space for a few minutes.

Any tip? thx

I clean the following location with a batch file and it cleans out more than any other Windows-included tool:

There are several locations that I mentioned here and Windows does not clean with it's tools.
