It's common for files to be locked in this folder since they aren't always junk, sometimes they are in use by a running application. Try deleting them after a restart. If you can't get them all its not a big deal. Don't micromanage, as there are much larger portions of the OS that can be optimized for a much better effect.

CCleaner is a freeware system optimization and privacy tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. But the best part is that it's fast (normally taking less than a second to run) and contains NO Spyware or Adware! :)
Maybe some .dat file are used by the current applications. they are marked "read-only'. It 'd better not to remove them. IF you want to remove, boost your computer by a Bootable Cd (WinXP setup Cd), get to MS DOS mode.

type (from command mode, press Enter after each statement)

cd \

cd windows\temp

delete *.dat
