Just got a new dual core Dell XPS with vista x64 - once it's at the login screen and I log in, the had drive goes nuts for almost 10 minutes. Any ideas on what it' doing? I did take a peek at the resource monitor and it's processing all sorts of stuff like all the office documents I've worked on and civilization 4 files and a bunch of other stuff that has nothing to do with booting up.
First thing , Don't worry this is normal for a new Vista install :D
What you are seeing is the Vista File Indexer - It is building it's initial index and depending on how many files you have to index can take a while as the index for a lot of common files includes the contents, and metadata as well as the file names.
The main reason that it does take this ling is that it is set to stop as soon as it detects any user activity at all. If you can the best thing is to boot into vista and leave it running for a few hours without interruption - Overnight is best if you can.
The is a control panel item to control Indexing Options if you need to tweak the types of files or the locations indexed
