Then, right-click on the Google key, select New > Key, and name it Chrome. Following that, you need to create a REG_DWORD value. To do that, right-click on the Chrome key, select New > DWORD (32-bit) Value, and name it as ScreenCaptureAllowed.
By default, it carries a Value data of 0, and you need to keep it that way to block screen capture on Google Chrome. However, if you want to allow it, you need to double-click on this REG_DWORD value and set the Value data as 1.
Then, click the OK button and restart your computer. Alternatively, you can also delete the REG_DWORD value as well. For that, right-click on the ScreenCaptureAllowed, select the Delete option and click the Yes button.
Like the GPEDIT method, you can allow some origins to allow the screen capture in Chrome. For that, you need to right-click on the Chrome key, select New > Key and name it as TabCaptureAllowedByOrigins. Then, right-click on the TabCaptureAllowedByOrigins key > New > String value, and name it as 1.
