Under normal circumstances, the Windows7 menu bar does not appear, if you need to use the menu bar to press the ALT key. However, after using some software, the Windows 7 menu bar has been permanently displayed, how not to switch.
Having the Windows7 menu bar permanently displayed can be handy for some of your operations, but it also gives other users the opportunity to modify the system settings, and perhaps at some point you may find that some of your own personalization definitions have been tampered with.
If you want the Windows 7 menu bar to be restored to the system default state, you can "send and receive freely" by using the ALT key, then follow these steps to cancel the Windows 7 menu bar always displayed.
1, first please confirm in the folder option is checked "Always show menu"
2. Open Group Policy Manager
If the Windows 7 menu bar is still "stubborn" when the option is canceled, enter the Group Policy Editor, win key +r to open the Run window, and enter Gpedit.msc carriage return.
3. Disable menu bar options in Group Policy Manager
In Group Policy Manager, expand User Configuration → manage template →windows component →windows Explorer, and then double-click Show Menu bar in Windows Explorer in the right window.
In the window that pops up, modify enabled to disabled.
