Windowblinds Skining

showed up with Windows Addon

it does hook to other files also...
My firewall (Comodo) informed me wbsys.dll was trying to access the internet. There's no reason for it to access the internet, it's only for making Windows look different.
its quiet safe only skins windows, can slow windows down hud be left alone
It is used in WindowBlinds, but somehow my Comodo Personal Firewall is acting weird and won't let me access the net once I allow the file to be allowed
Windows Blinder Files for theming xp remove it if u dont have the software waste of space but need it if the software is there
Uninstalled it because it always was slow to end (kill) or lagged when shutting down Windows.

Windows XP Desktop enhancer. When you uninstall it, it leaves a lot of .dll files behind which can slow down your system. Autorun startup initialization dll , Delete through Autoruns Process Utility if you don't have Window Blinds installelled on your system

No security risk, its a process related to WindowBlinds. It does hook onto other applications, but remove if you no longer got WB installed.
I do not, nor have ever had WB installed on my computer and this file was picked up by my virus scanners as dangerous, and it caused World of Warcraft to have a fatal error. Even "legit" files can be hacked and altered to malicious extent. This is clearly no exception.

Might be for Windows Blinds, personally I wouldn't know as I have NEVER had that program installed, and yet this file has been confirmed by my computer to be causing a crash in several other programs that I do use. Legitimate name or not, this can be deployed as malware.

Best practices for resolving wbsys issues

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

To help you analyze the wbsys.dll process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
