    Running Vista SP 2.

    Yesterday I discovered a problem with my desktop background. It was black and did not allow wallpaper or any background for that matter.

    I've run Norton AV and other anti-spyware programs and get a clean report. I've tried rebooting -- no change, remains black.

    The rest of the desktop is OK (shortcut icons, etc.).

    I tried a restore to a previous setting, but that fails, so that is a second issue.

    Is there a registry key that has changed to cause the problem? Any ideas?

    I've been "fooling around" with the registry (bad idea, I know, but I did not make any changes). Could not find any key reference to desktop background. If it is a registry key problem causing my continued "black desktop background", it is well concealed.

    I also setup a new user on this computer. Alas, it has the same problem with black background and not allowing wallpaper.

    I'm sure the fix is simple, but I just cannot find it.

    Is there any chance that this is a pirated (and well hacked) Vista? If it was pre-installed by a brand name OEM (Acer, DELL, Lenovo, etc.) this would not be the case. If was installed almost any other way there is a possibility even if you have no idea.

    Not at all likely. Vista came with my HP Computer I purchased over four years ago, and it has been pretty much problem-free. This is a very recent problem. Everything ran normally a week ago.

    Can you do a System Restore to shortly before the problem started?

    As I mentioned in my first message, "I tried a restore to a previous setting, but that fails, so that is a second issue.."

    have you looked in Task Manager>processes for an explorer.exe, if you have one highlight the entry and click on the End process tab-reboot. if you haven't got one then click on new task and type explorer.exe in, close down and reboot

    Thanks for the suggestion, Huggie. Tried it but no change.

    Desktop short-cut icons appear normal. Task bar is normal. Screen saver works. I can change the desktop background color to a color other than black, but cannot display wallpaper.

    have you tried this goto Control Panel > Ease of Access Center > Make it easier to focus on tasks> In reading section make sure that "Remove Background Images" is not checked. if not try checking the box apply-uncheck and apply

    Thanks again. That sounded like it might work. Unfortunately, it didn't.

    I appreciate your sticking with me on this.

    Found a suggestion to go to the registry key:
    HKEY_LOCAL_MACHINE\Microsoft\windows\CurrentVersion\Policies\System
    and delete what is there,
    There ar about 16 entries! I do not see any item that looks relavint to this problem and hesitate to just delete all of them.

    if you are going to delete any registry entries which I do not advise at this stage make sure you make a back up of the registry first

    I would back = up before I delete, but I do not think I will. This does not strike me as a solution.

    Things are getting worse with this computer-- and it is very frustrating.

    Here are some of the problems:

    Black blank desktop (continues)
    Cannot run Netflix Videos (OK on other computers)
    A newly adder User Account vanished
    No restore points although feature is set to create them regularly
    Script error message keeps appearing "An error occurred on the script on this page - object expected"
    Unwanted tab pops up on FireFox (Rootkit.sirefef.spy Trojan.fakeAV)
    Other unaskedfor tabs such as ond tellin me to update the browser -- I am using the latest FireFox 26
    Generally slow internet operation

    I have run the following in an attempt to fix the problem:

    Norton AV -- no problems
    Norton Power Eraser -- only reported registry keys regarding proxyenable, proxyserver and proxyoverride
    Sophos Virusmover Tool -- clean report
    Auslogics Boos Speed -- OK except for 6 file associations (which I have not found)
    Spybot S&D only found two tracking cookies which were removed
    AD-Aware -- Clean
    Kaspersky TDSS Killer -- no problems found
    Reinstalled Silverlight

    Yet the above problems persist.

    I have become reluctant to try other system scans and fixes for fear they might create even more problems.

    Is a re-installation of Vista the only remaining solution? Kind of Draconian.

    Perhaps I should consider buying an upgrade to Win 7. That would mean a lot of work getting all my apps and hardware drivers working on the new O/S.

    My XP computers are working just fine, thankfully.
