My assumption is that this "freedom" will be short lived. What probably happened is that your shadowstorage was purged and you start from scratch accumulating shadows (at least 1 per day) and that will chew up 1GB each time. If you give me the numbers, I can do the arithmetic for you. What I need is: Total C: and freespace before SP1 and Total space of C: and freespace now. You can also make a quick check: Type CMD into the Start Search. CMD appears above, right click on it and "Run as administrator". In the little black OS window type: VSSADMIN LIST SHADOWSTORAGE - Then read the 3 numbers for C: (USED; ALLOCATED; MAXIMUM) And let me know those figures.

Tara, you should start your own thread. It is not nice to hijack the thread of someone else - especially if the question is of a completely different nature.

There you go. During the next month or so Vista shadows will chew another 41GB's off your free space that you enjoy now, which will then get you to 229GB free. You are going to see, you will loose at least 1GB each day.
Shadowstorage is alway 15% of the total partition (e.g. C:). But as long as it is not allocated, it will show as free.

You are welcome. You did nothing wrong. This is business as usual. Keep checking with the VSSADMIN LIST SHADOWSTORAGE command (maybe once a week). You'll see how it's ramping up until it reaches the maximum of 43GB. Then it will delete the oldest shadows to write the new ones - kind of a round robin.
