Is the computer more and more closely related to us? Office, entertainment, many people’s main work of the day is to contact with the computer, a small screen, is what we look at most every day. Therefore, many people also lament that, with the use of computer time is getting longer and longer, health conditions are threatened, especially vision is not as good as it used to be. But if I were to tell you that using the most popular Win7 system now can effectively reduce the risk of vision damage, isn’t it surprising? In fact, we are through the Win7 system to set the window and the background color of the display to adapt to our eyes, as if we are in nature looking at the green grass, blue sky, is not more comfortable than against the monotonous, white background black text? First of all, we have to set the Win7 colors soft. I believe that many users are not unfamiliar with this point, right-click on the desktop margin, select “Personalization → Window Color → Advanced Appearance Settings”, and then the pop-up dialog box in the “Project” to “Window Then change “Item” in the pop-up dialog box to “Window” and “Color” to “Other”. Set Window Color In the pop-up dialog box, change “Hue”, “Saturation” and “Brightness” to “85, 123, 205″ respectively. 205” and then OK, the color setting is finished. The effect is very obvious after setting the window color. You will find that all the text editing area in the Win7 window will turn from the original harsh white to a softer bean green, and this color is actually the eye doctors have been recommending the color of vision protection. In addition to the background color to have “green” to protect eyesight, that shorten the time to use the computer can also be done to protect the role. However, we always forget the time and play until late without realizing it. So, here we need to take care of another function – “Timed Reminder”, and the same protective color, timed reminders can actually be achieved through Win7’s own function, and the module to achieve this function is called ” Scheduled tasks”. Click on the Start menu and enter the word “Scheduled Tasks” in the search bar at the bottom to find the “Scheduled Tasks” module. At first glance, this interface seems a bit complicated, but it is much simpler to operate. First, click “Create Basic Task…” on the far right to create a new task, and then determine a name for the task (e.g. “Timed Break”), then click the next page to change the trigger to “Then set it to “Occur every 1 day” in the detail settings page. Set the time Next the system will ask when the task needs to be performed, we just need to select “Show Message”, and then write a reminder text (such as “time to rest, leave the computer for a while ~”), so sure that Win7 will be able to perform regular reminders operation. Of course, the reminder is still a bit rudimentary, and can only be used at a fixed time of the day. In fact, we just need to right-click to bring up the properties panel of the task, open the “Trigger → Editor” sub-option, and then check the “Repeat task interval” and select a suitable time (such as 1 hour), and then the ” Duration” is modified to “Indefinite”, Win7 will automatically pop up a reminder every once in a while.
