Shadow copy on windows 2008 server

Hello dear friends,
I am having error while disabling the volume shadow copying service on my windows 2008 server which is installed on Pentium Core 2 Duo System having 4 of RAM.
The service was enabled, but it is not in use for any of our official activity. So, being on safe side, I tried to disable it so that resources used by this service become available to operations.
But when I try to do so, I was greeted with following error:

Error
An error was encountered while attempting to browse the contents of shadow Copy Component.
A failure occurred accessing the Writer metadata.
Please put a light on the consequences of disabling this service and the way through which I can attain this objective.
Thanks.
