Let me share the solution with you, welcome everyone to read and learn.

When encountering this kind of problem, we first look at whether the other party has entered the wrong account, such as whether she has entered the guest account.

We start by clicking on the Start Menu - Sign Out.

After the dialog box pops up, we can select "Switch User", where we can choose to log in to your previous account, and we can find out if you have entered the wrong account. Usually we have an administrator account.

Another method may be that you have done a restore on your computer, and you have done a one-click restore on your boot. Or maybe you made a mistake restoring your settings. At this point, we can right-click on my computer and select properties.

In the dialog box that pops up, select Advanced.

In "Startup and Failback", click "Settings".

There is also a possibility that your system settings have been changed somehow. We can do this by following the steps below.

Let's click on the start menu, click on "Run".

Enter it in Runtime". Point OK.

Under User Configuration, select Administrative Templates.

Double-click on the right to open the Desktop.

Find "Don't save settings when exiting" and double-click to open it.

A dialog box pops up, and we select the "Disabled" point applied. Rebooting will do it.

If the above methods still don't work, it is estimated that your computer has been poisoned very seriously, and the files have been changed a lot. Upgrade the antivirus software to the latest level, restart it, and press F8 to enter safe mode to prevent antivirus. If you look at it again, you can only reinstall the system.
