E.g. there is AutoCAD and Corel Draw installed on my Notebook. I bought those Apps some time ago. Can I let others use it and charge for it (per minute?)?
It will depend on the terms of the End User License Agreements (EULA) for the applications in question. Generally speaking, the answer is no. You would be violating the terms of the license agreements; several large software providers have default license terms to prohibit this. For example with Microsoft products you need a Service Provider License Agreement (SPLA), not their common retail version EULA, before you can 'rent out' Microsoft software.
Your intent would likely matter as well. If you do it just once, to help a friend, nobody is likely to care. If you're essentially trying to build a recurring business primarely based on giving people cheap access to AutoCAD without AutoCAD seeing any money, then the courts would likely go harder on you.
So, to clarify:
As always, please go see a qualified lawyer about this, don't take the words of a layman as me. But one thing, as an entrepreneur I will say don't try to build a business that is very directly positioned against the interests of large software vendors -- they have large legal teams and are not afraid to use them.
