unable to change account picture in windows 8

I have recently upgraded to Windows 8 operating system on my computer. After successfully installing the OS I was trying to get used to it by exploring all the settings. One thing that I have noticed is that if I go to Charms Bar > Settings > Change PC settings and here I am not able to change the lock screen wallpaper. When I click on browse then it will simply freeze. I was also attempting to do the same thing for changing the profile picture but it again freezed. So if anyone has some idea how to fix this it would be helpful. Thanks

I think that you will have to turn off the lock screen slide show because you might be having only 1 picture and it will stop any error message that you are getting. To do that open PC settings and then click on Lock Screen which is located at the right side on PC and devices on left side. After that click on Lock screen on left side of PC and devices and then on the right side under Slide Show, move the Play a slide show on the lock screen slider to the left to turn it off. When you are done then close this PC settings.

It might be possible that there could be some problem opening the browse screen completely. You can check the part of it which is located below but nothing above it where you need to select the images from. So to fix this, you should try to run sfc /scannow command which might be able to help you out if there is some corrupted or modified system file in your computer. If this problem started happening recently then you can also try to do a system restore using a restore point dated before this problem started.
