Alfa has not released a driver package for Alfa AWUS036NHA (Atheros AR9271 chipset) beyond Windows 7.
However it has come to our attention that AWUS036NHA can be stable on Windows 8, 10, and 11 using this third party driver. This driver was made for a different brand product which uses the same AR9271 chipset. Note that after installing, the device will appear in Device Manager as "TP-LINK Wireless USB Adapter" instead of Atheros or Alfa. This is because TP-Link is associated with Microsoft as the Device Developer ID of this driver package.
We have tested the driver extensively and it appears to work with the Alfa AWUS036NHA well. However it should be considered a beta driver until further notice.

Thanks a lot mate.
WORKS! After Hours how to run AWUS036NHA under Windows 10. Thanks.
forgot to mentioned
click on browse my computer for driverS
also when you install the drivers from the links that i provided
the device is properly recognized as Atheros AR9271
as recently as march 2021
this is what i found that it works on windows 10 64 bits version 20H2
simply download the cab file directly from microsoft
extract the cab file to a folder using winrar
then send the extracted folder to my documents
now go to device manager to install the drivers
if the driver path is set to default
meaning my documents then all you have to do is click next and it will automatically
will detect and install the driver files
if you change the path because you install a previous driver manually
then make sure to set the path to my documents
i will try to find a newer driver version then will post the link
but for now this one will do
this is just the driver, without any app
you can use windows built in wifi scanner app
these are the links
