I just can't resize my partition in Windows Vista. I've tried the partition manager, but I get an error: Logical Disk Manager, Access Denied. So I used diskpart.exe, but when I tried to shrink my partition, I got access denied again! Booting in "Safe Mode with Command Prompt" doesn't work, nor does activating the hidden administrator account. How can I shrink my partition?

I would recommend not using the built in Windows tool for this task, even if you were to resolve the Access Denied problem. Unmovable files such as the page file, etc, usually prevent you shrinking the partition down to the size you actually want anyway.
A way around this is to use a free tool called GParted. Download, burn to a CD and boot into it. You will get a familiar interface which will allow you to play with your partitions. As it runs outside Windows, there no Access Denied errors and nothing stopping the unmovable files from being moved.
