Problem Description:
The win10 operating system, due to the development of opc before, has changed the system permissions, which causes every time the computer is started, the toolbar at the bottom of the desktop
The search button and the network connection button cannot be used, and there will be error prompts such as windows cannot access the specified device path file.
solution:
1. Find Task Manager –> Details –> explorer.exe. End mission.
Click File –> Run New Task –> fill in explorer.exe, click OK.
This solution can solve the problem that the search box and the network connection button are invalid. But you need to do this every time you start up.
2. Open the Local Group Policy Editor and enable "User Account Control: Administrator Approval Mode for Built-in Administrator Accounts" in "Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options".
3. Check the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\EnableLUA value in the registry, usually it should be set to 1. If it is invalid, some people suggest trying to set it to 0.
4. The ultimate method ----- system restore, reset, reinstall~
