Desktop Is Anbormally Large

Hey guys, any help on this is greatly appreciated, Thanks

I try to keep my computer on as much as i can to avoid the long start up procedures and as i am on it 10/24hrs of the day i have no need to shut it down.

I recently was required to restart my computer to complete an installation process. When I turned my computer on I noticed that the desktop (Start menu, Task bar, Icons) were abnormally large. I figured that the screen resolution had changed(from the install), but it is still running at the maximum for my laptop (1360 x 768).

The start bar inst too noticeable but it has changed (see (1 - My Task Bar) and (2 - Generic - Old Bar))

I would like to have it back to the way it was and any help/ suggestions from you guys/girls would be very much appreciated :)

Thank you Arc And hannah for replying, Arc - that was exactly the problem although i have no ecolection of changing this.. A big thankyou for your swift reply, knoledge and for being friendly :) .... despite my lack of a brain
