Best practices for resolving exec issues

A clean and tidy computer is the key requirement for avoiding problems with exec. 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.

Use the 6resmon command to identify the processes that are causing your problem.
