Deleting Vista Home Shadow Copies: A quick & dirty solution

So I've wondered, is there an easy and comfortable way to delete the volume shadow copies in vista home professional?
And am I right in assuming that deactivating the volume shadow copy service has no negative effects, or is it not a good idea because other windows tools need it too?

    Up to you, I think it may break windows update though. If an update goes wrong it relies on shadow copies to my knowledge. (I think)
    I believe it'd also break system restore too, so if you use system restore you won't be able to use it.

    I'll boot into my vista partition later and check.

    hm, ok
    So how do I delete the files and where are they stored? I think the shadow copies are taking up about 20GB, and all that for files which I have already on backup disks

    anything? shadow explorer allows me to view the files, but I would like to delete these absolutely unecessary backups altogether
    edit: apparently, running "vssadmin" in an admin dosbox lets me change the max size and various other settings of the volume shadow service
    hmm..
    vssadmin resize shadowstorage /For=C: /On=C: /MaxSize=300MB
    

    apparently resizes the vss storage space to minimum size and deletes all files. I did that and then set the size back to 30GB.
    Got 30 GB Hdd space back :P

    Wow that's ridiculous, surely there is some way to enable it.

    eh, that command seems to do the trick.. but yeah, having an official way to do that would be kinda.. better
    anyone got an idea?

    I made a .bat file called vssdelete.bat and put these two lines in it
    vssadmin resize shadowstorage /For=C: /On=C: /MaxSize=300MB
    vssadmin resize shadowstorage /For=C: /On=C: /MaxSize=30GB
    
    Running it as admin will basically delete everything but the most recent system restore point
    Change the "/MaxSize=30GB" part to whatever "vssadmin list shadowstorage" (again running cmd as admin) tells you you have set before, or don't use that line if you want it to stay that small and not waste hdd space
