Source -Yes, that is a word. If you’re about to order a lovely new PC with Windows 7 on it beware that you might not get the lovely speedy new system that Windows 7 promises to deliver. This is because of crapware. The sheer volume of useless software that can come pre-loaded with new PCs can have a serious effect on performance.
