What you wrote about is what an OEM can do without any fear of Microsoft's reprisal. In fact because of the OEM agreement the OS does not have to include ANY feature or item since the support is between Dell and they customer. To cut support costs such things vanish.
Not much new here but I continue to bump into folks new to how OEM licenses work and some of them compare what they get in the Full Retail version (which is where we begin the conversation.)
Dell stopped shipping the popular Backup and Recovery Manager v1.3 with Windows 7 Computers in May 2014 .
Dell replaced it with Dell Backup and Recovery Basic v.1.6 and later 1.7. This version was written for Windows 8.x and it disables two important functions of Microsoft Windows 7 Backup and Recovery.
The "Create a System Repair Disk" no longer functions and more importantly the "System Restore from an Image" is also disabled.
Uninstalling the Dell software will restore the "Create a System Repair Disk" but the "System Restore" remains unusable.
The "Basic" version of Dell's software has very few functions and is a marketing ploy aimed at getting the end user to purchase their "Premium version" which restores the functions previously available in their "Backup and Recovery Manager" v.1.3
Anyone who purchased a Dell computer after the first of May and has Dell's "Basic" version will not be able to recover their computer with an Image if they have a major failure.
I wonder if Microsoft knows what Dell did to their Windows 7 Operating System?
