click on `tools`, then click on `internet options`,
under the general tab click on `delete files` in window click box `delete all offline content`. Then click `okay` in same window.
This will clear all off-line sh1te from your temp folder.
Then finally click `okay` at the bottom.
This should speed up your PC a little if not a lot :D
don`t know if it will work the same on wireless box of tricks, but worth a try
