Windows11 Right Click Menu

I recently purchased a mini PC, the most expensive one I've had for myself in a very long time, and before I knew it, I was a Windows 11 user (lol), and I've been using it with almost no problems. However, there are some differences, and the most troubling is the mouse Right-Click.
As I wrote in Keyboard Operations in Windows, I am a command line lover by nature (:-), so I try to use the keyboard without using the mouse as much as possible in Windows. Of course, I use the mouse if it is more convenient, so the typical example is Right-Click. Especially in Windows Explorer, Right Click + m (Rename) is very useful. This is not only for renaming a file, but also for copying and pasting a file name in a program or report, Right Click + m + CTLR+c is a specific combination.
It seems that this Explorer Right-Click menu has changed with Windows 11. It may be possible to make it the same as Windows 10 by changing some OS setting, but that is against my policy of using Windows as it is (as much as possible) (:-o), so I need to consider alternative methods.
For some reason, the keyboard operation SHIFT+F10, which is the original right-click menu by keyboard, seems to be the same as in Windows 10, so this is my first choice. However, the drawback is that SHIFT and F10 are a bit far from each other. As the second candidate, after right-clicking, for some reason F2 seems to be used to change the name, so I am considering which of these two candidates to make standard. I would like decide soon ,since my finger has already pressed Right Click + m + CTRL+c several times without my permission and struck out (:-o).

Windows 11

I bought a MINISUFORUM UM350, a mini PC with high specs (relatively :-), and have started to play with it a little bit. My motivation is originally to make my old and slow computer usable using Linux , but such spec like Ryzen5 3550H Memory16G SSD256G is too high for such geeks (:-). It's like someone who used to drive on the freeway just under the speed limit on the lower side in a small car decades ago suddenly getting a super car (maybe not quite the same :-).
As for Windows, I am just an ordinary user, so I did as I was told about updates, etc. But I am sure it was Windows 10 when I bought it, but it seems that before I knew it, it is now Windows 11 when I thought some update had been run (:-o). With this high spec (in a relative sense), Windows Update is over in a flash, so I didn't notice it. In case of dynabook N40 with ATOM CPU, it took at least hous, sometime a couple of days for Windows Update. I am not a little bit ready for it, but I am now a Windows 11 user (lol).

Connection Spesific DNS Suffix

I bought a small computer called MINISFORUM and solved the initial problem with the keyboard. And now I am ready to use it! But as a nature of engineers (:-), I want to check various things before using it in earnest. This time, I also casually tapped ipconfig and found an unfamiliar domain name in the connection-specific DNS suffix field !?

I am not prejudiced against the country of origin of personal computers, but when I saw this, I was a bit scared (:-). Could it be spyware? Is there spyware in it?　I searched every file and registry and tried to check for viruses, but there was nothing that looked like that.
In conclusion, and this is a bit of a guess, but it seems that if you just remove the DNS suffix in the network settings, ipconfig will show the previous configuration values. So perhaps, but the configuration values from the computer assembly and testing process were still there. As proof of this, when I (fearfully) connected the computer to the network, this value disappeared.
I don't store any important information on my computer that could be stolen (really? :-), so I don't really care. , so I am not too concerned about it, but I wonder if it would be a big problem for companies that handle critical information. I am worried about that. I wish they would erase such information properly (lol).

Unifying Keyboard

In the old days, keyboard connections were made with a PS/2 cable, which I used for a long time, but nowadays it is completely rare to see such a connection. When USB keyboards were first introduced, many game players stuck to PS/2 because "I can't press the buttons at the same time unless I use PS/2! However, nowadays USB keyboards can be used for simultaneous pressing to a certain extent, and this has become less of a problem.
I also use a Bluetooth keyboard that can be connected to multiple computers for work and home use, but the purchase of the MINISFORUM UM350 has confirmed the necessity of a Unifying type keyboard. Of course, it may be a matter of course for those who frequently switch Linux OS (:-o).
Bluetooth is not recognized until after the OS is booted, so the keyboard cannot be used until the Bluetooth setting is made after the OS is first booted. However, without a keyboard, you are stuck in a so-called deadlock where the first setup is not possible. With Unifying, the keyboard is recognized by the UEFI (BIOS) before the OS is booted, so it can be used. Of course, if there is a UEFI that can recognize Bluetooth, it is possible, but I have not seen it yet. I don't know why, but I guess Bluetooth is too big to be included in UEFI.
Recently, Bluetooth + Unifying keyboards are available, and there are also Unifying USB keyboards that can be shared with multiple mice and other devices, so I'm planning to buy such a keyboard next time (I think it will be a while before I do so, lol).
