In Device Manager, Under Sound Video & Game Controllers, Right click the Realtek 2832U Device then click "Update Driver Software",
Click "Browse My Computer for Driver Software",
Click "Let me pick from a list of device drivers on my computer".
A 2012 Realtek 2832U driver should be on the list if you have previously installed the correct Realtek driver package. Select the Realtek 2012 driver, click Next to install the driver, the dongle then works and the 2012 driver remains installed.
If you can't see a 2012 in the Device Manager driver list or if windows is blocking the install of the 2012 driver, uninstall the 2832U device from Device Manager and delete the driver files. Then install the 2012 driver from its setup file. After Windows updates to the wrong 2009 driver, the 2012 driver will be in the driver list in Device Manager. Go to the list and re-install the 2012 driver. Windows does not re-install the wrong 2009 driver after that.
