XP system upgrade to Windows7 way to choose

        Q: I want to upgrade my system to WindowsXP Windows7, to ensure that all files other than the C drive are not affected, how do the original software is not to reinstall

A:?? In fact, this issue very simple, the upgrade to Windows7 WindowsXP there are two ways:

First, upgrade installation method (in the existing system, based on the upgrade of existing systems, data and software to retain the existing system).

The second is a new installation method (completely independent of installing a new system, nothing to do with legacy systems).

recommended a new installation, upgrade installation because it will inevitably encounter some unexpected problems. If the installation is new, as long as there is enough space in the partition, there will be basically no problem. In the new installation, format the C drive when Windows selects the installation location, and then install it (you can also boot to the Windows PE environment, format the C drive and then install it). As for the original software, of course, you have to reinstall it.
