This method requires registry editing, so be careful!
Run
regeditand navigate to:HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ExplorerLook for a DWORD value named
ScreenshotIndex, which stores the next screenshot's index:
To reset it, change the value back to 1
Note 1: If you already have existing screenshot files in the Screenshots folder, they will not be overwritten even after the counter reset. Thus even after resetting the value back to 1, Screenshot (3).png will be created in the example above (since screenshots 1 and 2 already exist). If screenshots 1 and 2 are moved/deleted however before a fresh screenshot is taken (after the reset of course), the new file will be saved as Screenshot (1).png.
Note 2: If you want to automate the reset, use the following command:
reg add HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer /v ScreenshotIndex /t REG_DWORD /d 1 /f You can also save the following as something like ResetScreenshotIndex.reg:
Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer] "ScreenshotIndex"=dword:00000001
