Windows 7: Windows 7 stuck on welcome screen?

Windows 7 stuck on welcome screen after installing VMware Workstation 7 ?

I have Win 7 x64 and I have one account on it without any passwords.
I've just installed VMware Workstation 7.0.1 Build 2276000, after that Win 7 stuck on welcome screen and I have to click on the user image to continue.
Before that because I have just one account Windows 7 just showed welcome screen for a minute and then it went to Windows 7 desktop automatically, but now I have to click on my account image to continue.



Something that I've done :

Start >> Run >> Msconfig
Services Tab >> Checked Hide all Microsoft Services
Disabled all services except Eset Services (Anti Virus)

Unfortunately the problem haven't solved yet
How should I fix it?

Go to Start and type in "netplwiz" (without the quotes) and press Enter
Left click once on your profile name
Remove the checkmark from the "Users must enter a user name and password to use this computer." box
Click on Apply, enter and confirm your password when asked
Click OK to exit the dialogs
Reboot and check to be sure it works.

yeah, it works.
Thanks my friend.
We also can use "control userpasswords2" instead of "netplwiz".

control userpasswords2 works on my Vista and XP systems - but not on my Windows 7 systems.
