Win8 system makes win+PrtSc return to 0 method

Friends who have used Windows 8 must experience the full-screen screenshot method win+prtSc in Windows 8.
We have a quick screen capture button under Windows 8: win+prtSc, everyone knows that prtSc is under Windows. Screenshots of shortcuts
But under Windows 8 you can quickly save your screenshots to C:
Users under the current computer name PicturesScreenshots folder via win+prtSc.
And take a screenshot (X). Named png, x increments from 1.
Most of the students hope that X will return to 1 after the screen capture, but tried a lot of operations and failed (for example, deleting the previous screenshot).
The value of X will still increase, and there will be no change.
After many efforts, we finally found a solution. Modify the registry.
Registry value location:
[HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorer]
If you need to restart sorting, we can change the value of ScreenshotIndex to the right of this registry root key to 0.
