This file is a protection/security for programs that are sold and utilize copy protection. ( For example UFO Aftershock Game Europe edition) Disable when not playing game, or your system crashes after installing game.

It is labelled as StarForce Protection Synchronization Driver. Starforce is a notorious copy-protection scheme used in some games. Version appears 19,968 bytes in size. The file is located in Windows/System32/drivers directory and is left behind even after the Starforce protected game has been uninstalled.

it prevented my computer from starting and i had to delete it by starting the computer in: last known good...
Protection for games
Causes serious crash on my 64bit system. Windows tells me to disable this driver as unsigned and cause of the problem. when i do it works fine again.
After installing a game from a few years ago, this file prevented my Windows Vista 64 from staring up. Had to boot from the instal CD and manually delete the file to get back into Windows. A recent version of the game software actually doesn't use StarForce any more, so it's no longer needed. More recent versions of StarForce do not seem to have this problem, and do not need this file.
sfsync02.sys is causing my computer to generate the error and I can't even boot my computer in any mode so that I can remove it. If anyone knows of a way to bypass that file on startup so I can remove it then please email me. (I put my name as my email address.)
Is a nonessential program that prevents windows from starting up. Easy to delete using DOS. Boot from CD, enter system info, open command prompt "cd" to the directory C:\Windows\System32\drivers and type "del sfsync02" to delete the file.

If you are unable to boot your computer using "last known good configuration" try hitting f8 when your computer is booting up and select "ignore driver files without signitures" or whatever it says along those lines. It worked for me.
Causes serious bluescreen of death and prevents booting since that occured
Caused infinate repair loop. Had to use a bootable repair dvd that i burned on my laptop. Bad program, DRM needs to go..
Installed GT Legends by SimBin (racing game) that uses Starforce. My Win 7 64 bit PC went into an endless loop with Scandisk trying to repair. Could NOT get back into Windows 7. Solution: Load a new copy of Windows 7 on another partition. Then go into the old installation and rename sfsync02.sys in your windows/system32/drivers directory to something else.

Best practices for resolving sfsync02 issues

A clean and tidy computer is the key requirement for avoiding problems with sfsync02. 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. 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 6resmon 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 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
