Windows 10: system reserve taking up 550GB

Hi This is crazy. System reserve taking up 550GB space. Does anyone know the fix?

Recovery Partition vs System Reserved Partition

Thanks for all the info guys.

Both original & target SSD's are listed as MBR as opposed to UEFI. I may have created a partition unknowingly in getting the original/new unformatted drive recognized, but I don't recall taking any steps that Windows did not step me through.

Not that an upgrade to WIN 10 Pro is contemplated, but I suspect that having no System Reserved partition will not allow that to happen, after seeing how the original WIN 10 upgrade created a problem for some WIN 7 users that had a smaller 100mb vs 500mb System Reserved partition.

 

system and reserved folder 550GB win 10

I found that a folder called $Extend is 550Gb

$Extend is a system reserved folder used by NTFS v3.0 or later. These files are required by the OS and should not be deleted.

System Reserved Memory issue

Hi Rowan,

The reduction in available system memory depends on the configuration of the following:

• The devices that are installed in the computer and the memory that is reserved by those devices
• The ability of the motherboard to handle memory
• The system BIOS version and settings
• The version of Windows 10 that is installed
• Other system settings

As an initial troubleshooting step, I suggest that you check your system for memory problems.

Here's how:

• Type mdsched.exe in the search bar and select the best match.
• When prompted by the User Account Control, enter an admin user name and password, and click
  Yes.
• Follow the on-screen instructions to run it.

Let us know how it goes.
