Killing running processes.

Use Task Manager to end running processes. You can call Task Manager by pressing CTRL+ALT+DEL key combination, or right-clicking "Taskbar" and selecting "Task Manager". "Application" tab shows running applications, "Processes" tab - running processes. Choose the process you want to end and click "End" button.

Unregistering DLLs.

You can unregister DLLs by entering proper string in command line (START/RUN). Regsvr32 allows you to unregister unwanted DLLs. Command line syntax: regsvr32 [/u] [/s] [/n] [/i[:cmdline]] dllname.

/u - unregister server;
/s - silent; display no message boxes;
/i - call DllInstall passing it an optional [cmdline];
when used with /u calls dll uninstall;
/n - do not call DllRegisterServer; this option must be used with /i.

After DLLs are unregistered, reboot the computer.
