In 1995 a new OS appeared. It incorporated major changes that thwarted people from backup of "program" due to features that we know as:

- The registry.
- Shared DLLs.

In NT, 2000, XP and beyond, the company added...

- Permissions.
- Ownership.

As such, it's been about 9 years and no backup has shown itself capable to backup a Windows "program".

What to do?

Organise yourself and keep your programs ready to be reinstalled.
