Rebooting Windows without rebooting windows

What the hell is he going on about?

After a few days of using my NHS PC it becomes slow so I close everything down and reboot it which I hate doing.
What would be great is if I closed all software down and then ran a piece of software that emptied the caches so it feels as though it's just been rebooted.

Is there such a thing?

Yes, logging off does this...

You sure?
It doesn't seem to put me back to full power.

OK, I'll test it just before I go home, what you're saying makes total sense.
These Win7 NHS PCs are so slow and get clogged very easily.
