Windows 10 install – Not enough memory

windows 8.1windows-10-upgrade

I am attempting to install Windows 10 on my desktop.

I got an error in the "Reserve Windows 10" app stating that I need at least 2GB of RAM (I am installing the 64 bit version).

I downloaded the media creation tool, hoping to bypass the Reserve app. The media creation tool still says I do not have enough Ram though.

The full error message: "You need to install at least 2 GB of RAM before you can install and run Windows 10. Contact the PC manufacturer to see if you can install more RAM."

I have 12GB Ram installed. 2 x 2GB modules and 2 x 4GB modules.
I swopped out modules, removed them, used one at a time, all modules are working fine and are recognized by Windows. The install simply wont work.

I have tried the following configurations for my Ram (A = 4GB same brand, B = 2GB same brand):

  • A B A B
  • B A B A
  • A _ _ _
  • A _ A _
  • B _ B _
  • B B _ _

I am currently running Windows 8.1 Pro as my OS.

EDIT 1

There was a bug with the technical preview and some VMs stating not enough physical memory. As I am open to any ideas I removed "Windows 8.1 Update KB2995388", this did not fix the problem.

EDIT 2

Some system info from dxdiag.exe:

dxdiag info

The error message:

"This PC can't run Windows 10" Error message

EDIT 3

The question is being asked on other forums as well (not by myself) with no helpful answers yet. Links I have found so far:

Link 3

EDIT 4

As per suggestions in the comments I tried the following:

  • Changing the page file
  • Swopping out the Ram stick in even more configurations
  • Running memtest86+ (No errors reported)
  • Installing from external media (both USB and DVD)

Some extra info, if it may help at all. A screenshot of the resource monitor's memory tab:

Any other solutions I can try?

I had a similar issue like this when I attempted to install Windows 10. However, this was from a preview build. (Ironic right?)

I disabled Windows Management Instrumentation. This can be done by disabling the service via Win+R -> msconfig then selecting the tab Services and finding the Windows Management Instrumentation then unchecking it and rebooting.

If you do not wish to reboot, just start up services.msc (Win+R -> services.msc) and then stop the Windows Management Instrumentation service and it's accompanying dependent services.

The setup will now proceed as expected.

This service provides extensions to the Windows Driver Model. Disabling this most likely removes access to critical checking functions, which results in the installer getting some sort of satisfactory results on the pre-checks.
