How to reset Win8 ClearType settings?

Many Windows users have discovered and tried using the ClearType text tuner built into the system. Its interface is shown below:

However, I believe that in the position shown in the second picture, many people are as confused as I am. After the adjustment, I found that the display effect is not as good as that.

How to restore it? This is a difficult problem. After some searches, including some foreign forums, most people have not found a solution. Some people say that they can be re-elected in a certain order. After I try, this is still not possible. . Moreover, even if different monitors are connected to the same PC, the procedures and steps for selecting the clearest text may be different. (I am like this.)

How should I reset the settings? It seems that only analysis. With ProcMon, unsuccessful, the specific reasons have yet to be verified. However, by searching the developer's resources, I found some information about the screen settings on MSDN.

1. Go to the registry HKCU\\Software\\Microsoft\\Avalon.Graphics. Below, there are several monitors that will generally have How many keys are named DISPLAY1, DISPLAY2, …, DISPLAYn. All we need to do is click on each of the DISPLAYx keys and delete all the keys on the right side (except for the default " Normally, the ClearType tuning should not look like this:

2. Go to the registry HKCU\\Control Panel\\Desktop, below, find four key values ​​that start with FontSmoothing. Set to 2,0,1,2 respectively.

3. Log out of the currently logged in user and log back in to restore the settings and reset the adjustments made by the ClearType tuner to the system default state.

Okay, it can be seen from this that the ClearType of the user interface is per user related settings. This is reasonable, because each user sees the effect of the screen text is different, there should be personalized preferences for each user to save. However, I hope that Microsoft will improve this tuner function in the next version of Windows, making it more practical and user-friendly.
