Windows 10: USB drive having SSD shows read only

Recently, I connected a new SSD as a USB drive. It shows "Write Protected" in windows 10. However, same one if I connect to Windows 8.1, then the write protection is not there. Can not do driver update under windows 10 as it is write protected. Has anyone faced similar problem? Your assistance will be appreciated.

External SATA3 SSD to USB (512GB Crucial MX100 SSD) showing up as a Hard drive in Windows 10 Defragment and optimize drives?

When checking the Windows 10 Control Panel feature Defragment and Optimize your drives, my 512GB Crucial MX100 SSD installed

in a Nexstar (NST-266S3-SV) 2.5" SATA3 to USB 3.0 external HDD/SSD Enclosure shows up as a Hard disc drive (not as a solid state drive)?

I've tried uninstalling it, restarting Windows 10 with no change to the SSD showing up as a Hard disc drive in the Defragment and Optimize your drives feature. I've unplugged the enclosure and plugged it back in to the same as well as different USB ports
with no change.

The 512GB Crucial MX100 SSD shows up everywhere it should, is easily accessed, runs at 450MB/s Read, 420MB/s Write as an external USB storage device (using numerous SSD Benchmarks), has the latest Crucial firmware and driver, shows up as healthy in SSD Storage
Tools, etc.? My ASUS G751JY notebooks two internal drives (512GB OEM Samsung SM951 PCIe M.2 OS SSD & 1TB Samsung 850 Pro Storage

SSD) show up correctly in the Windows 10 Control Panel Defragment and Optimize your drives as Solid State drives. The ASUS G751JY

notebook has the latest ASUS AS211 BIOS and all the latest hardware drivers as well as Windows 10 updates?

Any and all suggestions appreciated, I'm stumped. The only good thing is that despite showing up as a Hard disc drive, everything runs & works perfectly using it as an external 512GB storage SSD.

 

Purchased Windows 10 on USB from Microsoft Store

I just received my Windows 10 USB from the Microsoft Store. It is write protected and shows up as "Read Only" instead of "Online" in Disk Management. Not only is the USB write protected, I also can't change the drive letter because the "Change Drive Letter
and Path" option is grayed out. The normal writable USB flash drive allows me to change the drive letter but not the read only retail Windows 10 USB from Microsoft. Why won't Windows allow me to change the drive letter of the read only USB drive?

 

I had this on my c drive SSD, I signed windows out and the disk was no longer write protected. Why it happened in the first place, I don't know.
