How do we keep the winsxs folder from growing exponentially?
Like others we just discovered that these winsxs folders are growing over 10GB in size. An on simple virtual servers with single websites we have several over 10GB in size. The plan was to only have 20GB drives on our SANs but these folders are consuming all of the disc space.
Are there any version of 2008 where the winsxs folders are not continually growing?
Talk about a wast of expensive SAN space.
Anyone tried deleting the contents of the winsxs folder?
Example 12.4 Gig file with 62,272 files in it and 15,443 folders in it.

Hi,
Its not good to delete content inside the winsxs folder. Rather you can increase disk space up to 50 GB. Moreover it is recommending system drive disk space by MS.
Also few more suggestions are for you.
- Configure page file and split it into two partitions instead of keeping whole in only C drive.
- If you have any applications (like SQL, other backup tools) use non-system drive to store application data instead of storing data inside program files.

You see a solution in those links????????????????????????
I see a tool that shrank it 3GB but is NOT a solution. I'll repeat what I and others have said that we have virtual servers with small hard drives that this is consuming.
Am I to expect that this folder will grow forever and we just need to always increase the drive size?

Hi,
"The only way to safely reduce the size of the WinSxS folder is to reduce the set of possible actions that the system can take – the easiest way to do that is to remove the packages that installed the components in the first place. "
For more information please refer to:
What is the WINSXS directory in Windows 2008 and Windows Vista and why is it so large?
