Yes! You definately want to delete browsing history and delete temporary internet files. That will make things even faster. You should probably do that weekly just for general housekeeping.
You also want to go to Start> All Programs> Accessories> System Tools > Disk Defragmenter. Defragment the disk after deleting unwanted files and internet temporary files every month. Fragmentation causes a lot of slow down of your computer because the head is having to travel all over the disk gathering bits and peices of the fragmented files.
