A series of tests have revealed that even newer Windows 7 PCs are being bogged down by unnecessary software that makes them run much more slowly than Macs. Comparing factory versions of several notebooks versus clean models, PC Pro finds that Acer and Sony systems take about two whole minutes more to boot because of the "crapware," or third-party utilities and trial apps, preloaded out of the box. They also consume roughly 1GB more extra active RAM and also rob the system of as much as 2.4GB of space in Acer's case.
