I have one drive which is split into two partitions. One partition has Windows 10 installed and another has Windows 7. Does removing a drive letter trought Disk Management in Windows 10, of Windows 7 system and vice-versa, prevent Windows Defender from scanning the other systems files?
Thank you!
A partition without drive letter in this Windows installation cannot be accessed by normal Windows applications and is in effect invisible. It will also no longer be shown as a drive in File Explorer under "This PC" and not be scanned by Defender.
Removing the drive letter is a well-known method for avoiding any Windows access to a disk or partition.
