In the past I used USBtiny and USBasp programmers to flash Atmel microcontrollers. Under Windows 10 the programmers did not work, even though Windows 10 seemed to detect them correctly.
It turns out Windows 10 does not use/fetch the correct drivers.
To make things work again most folk use Zadig a tool which automatically installs some legacy drivers typically used for USB programmer dongles.
After the drivers are installed Windows 10 finally detects my USBasp programmer dongle as it should.
