Windows 10 Anomalies

Anomalies are; abnormality, exception, peculiarity, oddity, irregularity, inconsistency, incongruity, aberration, quirk, rarity, etc...
The first thing that bothered me is the way MS was forcing Windows 10 as an "update" as opposed to an upgrade!  The next thing that bothered me was the way everything was "rearranged" AGAIN.  Why is it that every time there is a new operating system, all the parts I need to use are located some where else??  I don't mind change, but for goodness sake, make the changes intuitive or useful!!  Don't hide the control panel or my recent items, or my other favorite programs that used to be "right there"!
Now for the things that REALLY bother me!  Windows 10 automatically changes the formatting on your drive to UEFI and changes your BIOS without asking or without another option.
More on this later as I discover more quirks!
Other notes of interest:
1.  A UEFI system can't boot from NTFS, only FAT32.
2. A UEFI system can boot only from a GPT disk, not MBR.
3. A BIOS system can boot only from an MBR disk and not GPT, which is why you can't take an OS disk from a BIOS system and put it in a UEFI system and expect the system to boot.
4. Most UEFI motherboards come with a Compatibility Support Module (CSM), which is enabled by default.  If you want to run your system as UEFI, you need to disable the CSM via the motherboard's interface (see the screenshot below) before you try to install Windows.
5. A CSM makes the motherboard actually look like a BIOS system, allowing it to boot from NTFS and MBR disk--but you lose the UEFI features and are essentially just using BIOS.
6.  Graphics cards need to support UEFI Graphics Output Protocol (GOP), to be able to show information as the computer and OS starts. UEFI GOP replaces the old VGA format most graphics cards use.
7.  Because UEFI requires a GPT disk to boot from, whatever disk you install to must have all partitions deleted from so it can be configured as GPT.
8.  Your UEFI system can boot only from a device that has an EFI boot loader, so after the CSM has been disabled, the only boot devices that are listed will be UEFI aware.
