Best practices for resolving ContextMenuExt issues

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

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time.
