reinstalling system of pc

[Husar]

i didnt mean that. i just mean reinstalling windows 7, not an upgrade. i heard that u need to reinstall the system each year to let it run optimally.

Every week.

Other than that, do you notice any problems or significant slowdowns? If not, then there's probably no big need to reinstall. Older windows versions had a tendency to become really bloated and thuis can still happen, but I got much less of an urge to reinstall Windows 7 every year than say Windows ME.
