It may be that your operation time is a little long and the cache is full, which will lead to the abnormal switching of the language bar, the unresponsiveness of the right button, the disorder of the folder content and so on. Generally, restarting can solve the problem.

The reasons for this phenomenon are:

1, using QQ software is incompatible with the system, uninstall, and then download and install again.

2. Too many open programs interfere with each other. Close all programs (don't open too many web pages), including the monitoring of antivirus software. Don't kill viruses behind the scenes.

3. After running, the cache will be full (including too many open web pages), and various strange failures will occur, which can be recovered after restarting.

4. It may be incompatible with other programs or other input methods, and downloaded software or input methods that cannot be switched will be uninstalled and deleted.

This failure may be caused by registry corruption, and the solution is as follows:

1. Press F8 to enter safe mode, then exit, and then enter normal mode (repair registry).

2. If the fault still exists, please use the system that comes with the system to recover until there is no such fault (if the normal mode recovery fails, please press F8 to enter the safe mode and use the system recovery).

3. If the fault remains, use the system disk to repair it, open the command prompt and enter SFC/SCANNOW(SFC and/) to insert it into the original system disk repair system, and the system will automatically compare and repair it.
