Sometimes Tor doesn't working, starting to freeze since I launch it. I close it, launch again and it the same happens again and again until I reboot.
What is it and to do with it?
maybe you should reformat that windows pc and install a real OS, like linux Ubuntu for example
I'd glad to, but it's impossible bacuse of the university internet. There is no linux analog for the program, which is used to connect to tnetwork.
Let me get this straight. China went to the effort of creating its own official Linux distro (Red Flag Linux, based on Asianux and Red Hat), a distro adopted for official use by the Chinese government over a dozen years ago, a distro developed by a company which is now majority owned by the Ministry of Information Industry and your University in China won't let you connect to the network using it?!
Wow. That's special.
Telling the admins that you want to use the national operating system might be interesting. Depending on how much you want to annoy them. I'd avoid that, but if you start experimenting with Red Flag Linux you can always claim, if you get caught, that you thought it was okay to use the country's operating system. After all, it's better than Windows.
I think you'll find, though, that Linux is quite capable of connecting to the network, but the University admins just don't want to have to support it when people have problems. Systems Administrators are pretty similar around the globe: the last thing they want to do is actually speak to the users. The program will probably be some rebadged connectivity thing.
You may be able to analyse the connection to then work out how to connect to the network. Once that's done, even if there are other programs which require Windows, you can always create a virtual machine to run Windows and those specific programs when you need them.
