In this video, I showed two possible ways to fix the problem of black screen of death (BSoD) with mouse pointer (cursor) during start up in Windows 10. This problem is common for computers, laptops, desktops, and tablets running the Windows 10 operating system, either Home, Professional, Enterprise, Education. And could affect any PC brands like Dell, HP, Acer, Asus, Toshiba,Lenovo, and Samsung. In this situation, when you power up your PC, it loads up as usual until it gets to the point where you’re suppose to see your desktop, but instead of that it shows you an entire black screen with only your mouse pointer showing on the screen as you can see on this laptop. The most common cause is your user shell being corrupted either by some malware, applications, or system updates.
1. The first method is more suitable if you suspect that this problem could be due to certain malware changing the value data of your user shell, so to fix that you need to manually correct the value data of your user shell. To do that, while on the black screen press the keyboard combination, “Ctrl+Alt+Delete” at the same time, it should take you to a blue screen with different options, there select task manager from the list. In the task manager, click on the file menu and select run new task. You should see a dialog box, type in “regedit”, and then click on the check box below where it says “create this task with administrative privileges”, and then hit ok.
You should then see your registry editor page pop up. There you want to double-click on the folder “HKEY_LOCAL_MACHINE”, double-click on SOFTWARE, Microsoft, Windows NT, CurrentVersion, Winlogon. Here is a path address to the folder where your shell is located [Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
At this point you should have some files on the right side of the screen, there check for the file named shell and double-click on it. You should have a dialog box pop up. In the field under the value data, you want to ensure it says explorer.exe, if not then delete whatever you currently have in this field and type in explorer.exe. Then click ok to save the change and close the registry editor. Again press the keyboard combination, “Ctrl+Alt+Delete” at the same time, it should bring you back to this blue screen and on the bottom right corner you should see the power icon, click on it and select restart to reboot your computer.
2. This second method is more suitable if you suspect that your black screen error could be as a result of a Windows update you recently installed or some applications that you’ve installed and that you think might be causing this problem. Here we will be using the troubleshooting tool from advanced startup option to either revert back to the previous version of windows or boot to safe mode and uninstall the application that could be causing this error. To do this, while on the black screen press the keyboard combination, “Ctrl+Alt+Delete” at the same time, it should bring you to this blue screen where you have these different options, press and hold down the shift key and then select restart from the power options at the bottom right-corner, keep holding the shift key until you see the advanced startup option page. There select troubleshoot, then advanced options. If this black screen error occurred after you installed some major updates, say you upgraded from Windows 10 build 1709 to build 1803, then you can select the option that says go back to the previous version, and then follow the instructions to revert to your previous build. But if you suspect that this could be coming from an application you recently installed then you want to boot to safe mode and then uninstall or modify the application from there. To do that you want to click on startup settings. Then on the page that follows, click on restart. On the page that follows, press F4 or the number 4 on your keyboard and then wait for your computer to boot into safe mode. From here you can go to the Windows search and type, “add or remove programs”, and click on it, there you should see a list of all the programs you have currently installed on your computer. Then check for the program you suspect might be causing the problem, click on it and select uninstall to remove it.
