Apparently, Microsoft changed a lot of thing in its Windows 10 Technical Preview, and one of them is support for floppy disk drives. Microsoft no longer supports use of this drives for data transfer and reading, and is not specified why the company decided to make this move.
There’s no certain information about whether the support for floppy disks will return in the final version of the system, but one of moderators of Microsoft’s Community forum said that it is expected to return in the stable version of Windows 10.
You would say (as well as Microsoft’s developing team, as it looks like) that nobody uses floppy disks anymore, and that this method of data transfer and reading is surpassed a long time ago. Because there are other, more modern, faster and more capable ways of data transfer. But you would be surprised how many users are complaining about the absence of floppy disk drives in Windows 10.
One of the users who noticed that he’s missing this feature said this on Microsoft forum:
“I just noticed that my floppy drive was not installed in Windows 10, all I have is the device hardware ID ACPI\VEN_PNP&DEV_0700 and could not find any once else posting about this abnormality. I know there are some that think a floppy drive is not worth having but I use mine on occasion and would like support added back in.”
The best thing that Windows 10 Technical Preview participants who want floppy disk drives back could do is to report about this issue through Windows feedback, because purpose of this feature is to collect needed information from users about pros and cons of the system. Also, if you really need to use your floppy disks, I could recommend you to downgrade your system back to Windows 8, because even Microsoft says that Windows 10 Technical Preview should not be used in everyday work.
