One workaround that works on 32bit, (Not sure about64bit) is to find someone with a working version. Have them send you the contents of their working folder. Delete all the files in the LogonStudio folder that you have now and copy the new files into Logon Studio. It should now work. I have similar probs running the defaults and couldn't make any Logons. I found this out when Vista crashed and I had to resort to XP. I could make Vista logons on my XP but just could, run them and see my work as it would display and had to have a tester.

thanks your info worked great pass it on to others i had same issue i found that windows system 32\oobe\info\backrounds file and changed the name to backroundsdefault.jpg.bak and bam it's working again make sure you have administer rights to change files

I was having same problem (Dell Laptop, Win7 64bit) and this fix corrected the problem. It had been working until I double clicked on 'Windows Default by Microsoft' below screen listing My Logons. That is how the problem was created in my instance. Thanks for the fix. Love the program.

changing the name of my file in windows/system32/oobe/info/backgrounds - to backgrounddefault.jpg.bak  worked for me - i had the same problem -

thanks Koasati!

I have had the same problem with WIN7 Ultimate.  No Problem on a desktop running WIN7 Pro.

I have spent too many hours, downloading too many useless Freeware "Tweak" Apps .... Then I thought .... Why not look on the Wincustomize Forums???

5 Minutes to find Koasati's solution .... Which ..... WORKS!!!

Thanks!!! 

Thanks for all the help, the windows/system32/oobe/info/backgrounds/backroundsdefault.jpg to backgrounddefault.jpg.bak

How and where can i change  windows/system32/oobe/info/backgrounds/backroundsdefault.jpg to backgrounddefault.jpg.bak
plz help (koasati) 

oh never mind i got it worked thxxxxxxxxxxxxxxxx (koasati)

Sweet! I've been reinstalling programs after a recent hard drive failure, and LogonStudio would not work. Then I remembered I had to change something the last time. But what? Came here, did a search, and helped myself.   

Then I hurt my arm, patting myself on the back................   

LogonStudio used to work seamlessly on my past laptop. Recently, I bought a new desktop and after installing LogonStudio it didn't work. Odd, I thought? After searching for a fix, simply changing windows/system32/oobe/info/backgrounds/backroundsdefault.jpg to backgrounddefault.jpg.bak worked instantly.

Thanks for the assistance Koasati.

Sometimes, a forum search has exactly what you need.

To fix this properly do this.

• Go to Start->Run and type in regedit.
• Back up your registry using File->Export.

• In the tree on the left, navigate to the following key:

  HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background

• Double-click on the OEMBackground key and change its value to 0.

• Click OK.

The logon screen background will now change as expected.

I just made an account to tell you a big THANK YOU, because this's my first time using W7 and, hell, I started to panick when Logon didn't work
