The unknown Win7 system trick date bar displays week information

In fact, even if the Windows 7 date bar is not modified, it is very convenient to view the day of the week. Once you have a small tool, you can easily view the date and week by clicking the time bar, so the meaning of the modification is not great. Of course, this depends on personal usage habits.
Q: The default Windows 7 date bar only shows the time and year, month and day, and there is no information for the week. I think it would be more convenient to display it with the week. I don't know if Windows 7 can display the week? Table or what software is installed?
A: The specific operation method is very simple. Click the time zone of the taskbar with the mouse, click “change the date and time setting", and then click “change date and time”, then Click “change calendar settings” in the pop-up window to make the following changes:
short date (S) is "yyyy-Md dddd";
long date (L) is "yyyy' year 'M 'Month' d'day 'dddd'”
Then step by step to make the time zone on the taskbar display the week. This operation is not only suitable for Windows 7, but also for other Windows systems.
