Question: I want to upgrade my Windows XP system to Windows 7. What should I do to ensure that all files except the C drive are not affected? Do I need to reinstall the original software?
Answer: This question is actually very simple. There are two methods to upgrade Windows XP to Windows 7:
The first is the upgrade installation method (upgrading the existing system on the basis of the existing system and retaining the data and software of the existing system).
The second is the new installation method (install a new system independently and completely, without any relationship with the original system).
It is recommended to use a fresh installation, because upgrading and installing will inevitably encounter some unexpected problems. If you install it freshly, as long as the partition has enough space, there will basically be no problem. During a 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 it needs to be reinstalled.
