    Desktop wallpaper turns black after context menu delay

    Hi all, every time when I right-click the desktop, there is a 10 second delay before the context menu is shown. After the menu is visible my desktop wallpaper turns black when highlighting the desktop (black squares) or hovering over icons. Desktop wallpaper will return to original state after a couple minutes.

    My device is a newly imaged Lenovo Carbon laptop (Windows 10), with all driver updates from Lenovo, and all latest Windows Updates incl drivers/firmware installed. My context menu does not have any applications (already checked via ShellExView and registry checked on shellex\ContextMenuHandlers). This is a basic build with no Nvidia drivers installed, and disk/file integrity checks already conducted.

    Will also note, the desktop wallpaper is applied via group policies and cannot be changed. Any other pointers that I may check, before considering re-installing Windows?

    Have you followed the instructions at below link i know you said you have used the ShellExView program but i just want to make sure you did correctly.

    Using ShellExView to Determine the Problematic Extension

    Boot your computer into Safe Mode and let us know issue resolves.

    I would like you to check the system integrity of your Windows OS installation.

    • Please type cmd.exe into Start Menu search box.
    • Please right click cmd.exe and select "Run as administrator".
    • Please type the following command and press the <Enter> key: sfc /scannow (Please note that there is a space between 'sfc" and "/scannow".)
    • It should take about 20 minutes to run, if there are no serious errors.
    • If the System File Checker reports that some errors were fixed, but some remain; please reboot your computer and run the System File Checker from an Administrator Command Prompt, again.
    • If the System File Checker again reports that some errors were fixed, but some remain, please reboot your computer and run it a third time.
    • If "Resource Integrity Violations" (errors) are reported that could not be corrected, or were not corrected after a third SFC run, then please navigate to the folder: C:\Windows\Logs\CBS and copy the file "cbs.log" to your desktop immediately. I am asking you do that because that file is dynamic, so I want to be able to examine a copy that is unchanged from the time that the System File Checker was run.
    • If there are errors that couldn't be corrected, let me know and I will provide you with instructions as to how to upload the file.

    I have rechecked ShellExView and there were only two items which have been disabled with the same results. They were '7zip' and 'TheDesktopConextMenu Class igfxDTCM Module'.

    sfc scan was already conducted previously with no errors.

    Same problems occurs when logging in with a different user account. Will check safe mode and tinker with wallpaper gpo.

    Shellexview doesn't show all shell extensions.
    Try also Shellmenuview, and failing that, Autoruns (both free).

    However your description doesn't sound exactly like a shell extension related crash; you might even consider your graphics driver. Some people who've experienced explorer crashing have found they have needed to use an OLDER driver.

    Safe Mode would mean, of course, you're using a basic graphics driver.

    Finally got this sorted. Issue was associated with device not accessing gpo's over wifi (tied to wallpaper access). After the correct permissions (rules) have been made, then context menu appeared instantly.

    Thanks all for your time.
