Probleme mit Dienst Lexbce Server? Wie kann ich diesen Dienst löschen?

Get HijackThis from www.tomcoyote.org/hjt/ and install it in Program Files\HJT
NOT on the Desktop or in Temp!

Boot in Safe Mode, see how here.
Switch System restore OFF, see how here.
In Windows Explorer, turn on "show all files and folders, including hidden and system". See how here.  
Next, open Windows Task Manager by pressing CTRL+ALT+DELETE.
Click the Processes tab, select the process (if there) and click End Process for:
lexbces.exe

Next, click Start/Run and type services.msc and click OK. Look for the service:
lexbces.exe
Doubleclick it, click Stop if it's running, and change the Startup type to Disabled.  

Run Hijackthis, do a scan and FIX any lines with lexbces.exe in them.

Delete that file.
Delete ALL files from C:\WINDOWS\Prefetch.
Boot normal. When all OK, switch System Restore back on.

Now promise me, you will NEVER buy a printer from Lexmark/Dell again!

Click on Start/Run and type regedit and click OK.
Click on Edit/Find and type in lexbces and click Find Next.
If found, rightclick that and select Delete.
Press F3 to find the next, and repeat until the end of registry.
If you can't delete an occurrence (under LEGACY probably), just skip and press F3.  

Then reboot, and do that HJT thingie again.

I also found more on Microsoft's site. Article ID 324757, "Spooler subsystem app has encountered a problem and needs to close" and "Operation could not be completed" error messages
