Wireguard on Lightsail gone Ship-Wrecked

For a long time now I run an AWS Lightsail VPS serving as a wireguard gateway to my home server. Since recently connecting to the Lightsail instance via wireguard is no longer possible.
When I took a look with SSH I got

$> sudo wg-quick up wg0
[#] ip link add wg0 type wireguard
RTNETLINK answers: Operation not supported
Unable to access interface: Protocol not supported
[#] ip link delete dev wg0
Cannot find device "wg0"

To be sure I updated all packages, but the problem still persisted.
The port used by wireguard had not changed and still was accessible according to the network settings of Lightsail.
What change in the Lightsail VPS or network settings could cause an issue like this? It literally just stopped working over night.

USBasp driver for Windows 10

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.

USB driver installation with Zadig

After the drivers are installed Windows 10 finally detects my USBasp programmer dongle as it should.

More Windows 10 Issues

On my new Windows 10 installation I came across a few more issues:

LibreOffice did have a nasty offset where the mouse pointer would click way above where it was pointing. The solutions to this bug was to disable OpenGL rendering as described here.

Another bad experience was with VirtualBox which would sometimes boot up virtual machines with corrupted graphics where nothing is readable or even recognizable. The solution to this behavior seems to be to set the “Override high DPI scaling behavior” setting to “Application”; the setting can be found by right clicking on the VirtualBox shortcut/executable > Properties > Compatibility > Override high DPI scaling behavior. I found the solution here.

USBasp in Windows 10

Unfortunately Windows 10 does not accept the standard drivers for the USBasp programmer. The reason is that the drivers have no valid signature from Microsoft (as required by Windows 10).

The only way around this problem seems to be to temporarily disable signature checking and then install the drivers (if you are fine with the security risk). This is described in detail here.
