Twunk_32 is a 16bit to 32bit on the fly conversion tool for windows. Recent malware programs use this to run trojan scripts. If you have high system usage by twunk_32.exe I recommend taking ownership of the file and renaming it to twunk_32.old.exe. Then see if any programs are affected by it's loss. It is not essential to windows function but other programs may use it.

Best practices for resolving twunk_32 issues

A clean and tidy computer is the key requirement for avoiding problems with twunk_32. 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. Always remember to perform periodic backups, or at least to set restore points.

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. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
