VAIO PC's that have VAIO Recovery Wizard should have this file. This file is used to access the Recovery Tool on a hidden partition in the hard disk. You can find this file under startup items in System Configuration Utility. If partseal is unchecked you will not be able to run the Vaio Recovery Wizard
PartSeal is NOT necessary for WINDOWS. It is necessary if you wish to recover your original Sony software. It doesn't have to be running all the time, but if you have to use it, you're already in serious trouble and may not be able to choose to load it. I found a bunch of information at Sony's site, but it's all in popup windows that can't be linked to

Best practices for resolving PartSeal issues

A clean and tidy computer is the key requirement for avoiding problems with PartSeal. 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 repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
