[SOLVED] Windows 7 to Windows 10 upgrade checklist?

[captobx]

Preparing to update system from Windows 7 to Windows 10.

do I have to save data ? What about installed software?

You should always be backing up data at all times, not just when upgrading the OS.

And you should always be prepared to run a full, fresh Windows install, if it's necessary.

Those are the only two things to really watch out for.
