How to transfer windows 7 profile to windows 8?

Question

Windows

Hello. Actually, the question is in the subject, I want to reinstall my system from the seven to 8.1.
The problem is that simply updating is not possible, the installer does not offer this item. In addition, the windows easy transfer application is not installed on my current system and I cannot use it (during installation, errors about the lack of free memory fly out, although everything is ok with it). So, I need to transfer files and applications with their settings from one system to another, I did not find anything worthwhile as third-party software on the Internet
