My hardware is too weak to migrate to 10. (And, by the way, why to do it if my current system is working quit well, except this little one trouble.)
Your system is not working well.
It is completely broken and unsecure. Any script kiddie with 5 minutes of spare time could compromise your system and steal all of your data.
Hm, I can'st say that 2-core proc with 4 Gb RAM is light hardware requirements.
Linux runs with as little as 300MB RAM.
Depending on the desktop environment this obviously gets a lot more.
And, nore important, the Linux still user-hostile -- their programs not ever bother to put shortcuts on the main screen.
Do you really need so much clicky-pointy that you can't even put the shortcunts on the screen yourself?
Btw, there are dekstop environments which allow you to make a tick to have the shortcut on your screen...
