How to increase the c drive size in acer laptop

If you are out of space totally, just look online for a new hard drive. Although you can always clean fmoe files out, from the sounds of things you probably have 20 different trialware programs floating around the laptop, 3 toolbars, and maybe a couple of anti-virus softwares running.

Make sure you empty out the recycle bin to clear any files you may have deleted, go to C:\Windows\Temp, delete all the files in there.
