First, Windows key+space bar "space"

[Function]: Transparent all windows, quick view of the desktop (no need to switch)

[shortcut key]: win+ space

[Summary]: This is very useful when opening many program windows, and the desktop will have gorgeous light and shadow effects. Try the unused ones first.

Second, Windows key+D.

[Function]: Minimize all windows, switch to the desktop, and press it again to reopen all the windows just now.

[shortcut key ]: win+d

[Summary]: This function was available in the previous system, except that the display desktop of win7 was placed in the lower right corner of the taskbar (that is, the rightmost rectangular bar).

Third, Windows key +tab key.

[Function]: The legendary 3D desktop display effect

[shortcut key ]: win+tab

[Summary]: I remember that there should be a post about this effect, but I think this trick is the simplest.

Fourth, Windows key +ctrl key +tab key.

[Function]: 3D desktop browsing and locking (screen capture)

[shortcut key ]: win+ctrl+tab

[Summary]: I want to leave a picture after seeing its effect. Win+tab can't do di Win7 said-I can!

Five, Windows key+number keys

[Function]: For the fixed programs in the quick launch bar, open the corresponding programs in numerical order.

[Shortcut]: win+ number (1-9)

[Summary]: Woohoo, is this function cool?

Six, Windows key +P

[Function]: Open the setting window of external display.

[shortcut key ]: win+p

[Summary]: Office workers must be familiar with this function. By the way, connect the projector and switch quickly, hey hey.

Seven, Windows key+X.

[Function]: Open the "Mobile Center" setting window.

[shortcut key ]: win+x

[Summary]: The setting window includes various functions such as display brightness control, volume control, notebook battery monitoring, mobile phone synchronization setting, external display management and so on.

Eight, repair the system default file association

[Function]: Repair the system default file association.

[Shortcut]: None

[Summary]: This move comes in handy when we inadvertently destroy the default file association of the system. It's not as easy to modify file association under win7 as winxp. Do you believe it? try out

[operation method]: start->; Cmd, enter the association. XXX=XXXfile, the format is as follows.

XXX stands for file type, such as repairing the file association between TXT and BAT. These commands are related. TXT=TXTfile and assoc。 BAT=BATfile。

Nine, turn off the system sleep function

[Function]: Turn off the system sleep function.

[Shortcut]: None

[Summary]: The hibernation function under Windows 7 needs the support of hardware and operating system. There are many problems with this function at present. It is recommended to close it before the official version comes out, which can also save a lot of disk space (about 4G) for the system disk.

[operation method]: start->; Cmd, type powercfg -h off, and then press enter.

X.Windows key+keyboard direction key

[Function]: Quickly resize the window

[Shortcut]: win+↓↓→

[Summary]: When working and studying, if you need to see the contents of multiple windows at the same time, xp needs to slowly adjust the size and position of the windows by hand. Win7 provides this convenient and quick function (if it is two windows, just combine them ↓→), and↓↓↓ is to maximize and minimize the current window.

XI。 Modify the host and service files, but not the permissions.

[Function]: Modify system files such as hosts and services.

[Shortcut]: None

[Summary]: The user rights management of Win 7 is strict. By default, you can't directly modify files such as hosts and services, which indicates that you don't have permission. There are many tutorials on the Internet that explain how to get administrator or file permissions. If you just want to modify such a file, you don't have to make such a fuss, just make a small gesture * _!

[Operation method]: Copy other places except the folders of the host and the service file system, modify it with any editor, save it, and then paste it back to cover the system file with the same name.

Twelve, slimming right click "send to"

[Function]: Make the button on the right more refreshing.

[Shortcut]: None

[Summary]: After the system was installed and used for a period of time, when I wanted to give the whole shortcut of a file to the desktop, I found that the menu was too long ... Only the commonly used ones were kept, and the storage location of win7 was very different from that of xp, both under "C: \ documents and settings \ administrator \ send to", and the location of win7 was also different. Of course, by default, these folders must be hidden. If you can't see them, don't forget the advanced folder option to show hidden files and folders.

[operation method]: enter C:\Users\[ your current login user name] \ appdata \ roaming \ Microsoft \ Windows \ send to.

Thirteen. Running code

[Function]: At the beginning of opening, it is no longer possible to find and "run" the program.

[shortcut key ]:win+R
