There is a backup of the desktop on my phone. But when I log in to the cloud service on my computer, I can’t see the icon on the desktop. I only have SMS and contact software.

If there are no icons on the desktop and no icons on the taskbar after booting, it means that explorer.exe failed to load properly when the system started. The reason may be a routine program disorder, or it may be caused by malicious programs, Trojans, viruses, etc.

First open the task manager, click "File" - "New Task" in the task manager. In the pop-up Create New Task tab, enter "explorer.exe" and click OK to temporarily restore the desktop. If the desktop is not restored, explorer.exe may have been lost or damaged. You can give priority to restoring explorer.exe.

It may be that the Shell entry in the registry has been modified. Click "File" - "New Task" in the task manager. In the pop-up Create New Task tab, enter "regedit" and click OK. This will open the Registry Editor. Then navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon, and then check whether the Shell value under this branch is "Explorer.exe". If not, manually change it to "Explorer.exe". If there is no Shell item, add it, that is, create a new string, change the name of the string to "Shell", and change the value to "Explorer.exe".

At the same time, you can try to add an extra layer of insurance. Open "C:\WINDOWS\system.ini", under the first line "; for 16-bit app support", add the following two lines:

[boot]

shell=explorer.exe

If there is already content of "[boot]" and "shell=", but it is not followed by "explorer.exe", or "explorer.exe" is followed by something else content, you need to change it back, that is, change it to "shell=explorer.exe".

It is also possible that explorer.exe itself is missing or damaged. You can download explorer.exe from the Internet, use Task Manager to open "C:\Program Files\internet explorer\iexplore.exe", use IE to access the Internet, enter the link below to download the explorer.exe file, and then unzip it to C:\WINDOWS ( Before decompressing, if explorer.exe is running, shut it down first), and then re-run the exe.
