Best practices for resolving NscTop issues

A clean and tidy computer is the key requirement for avoiding problems with NscTop. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update.
