Windows 10 1809 update + KB4464330 can't set no paging file in System Drive (C:)

I finally found a solution to this problem. As someone already said in this thread, Windows 10 build 1809 doesn't allow to have the paging file on "portable drives" anymore. So if you click on the "Safely Remove Hardware and Eject Media" icon in the system tray and you see the drive that you want to use for the page file there, then Windows will refuse to use it. The problem is that the BIOS on some older motherboards seems to report the internal SATA ports as "external" ports to Windows. There are now two solutions:

• Deactivate this behavior for the SATA ports in the BIOS (it should be called "hot-swappable", "non-removable" or something like this). However, this seems to only be available on newer mainboards.
• Tell Windows that the SATA ports are non-removable.

I had to use the second solution. Here you can find a nice guide:

I'm not sure how to get the number of a specific SATA port, I also used 0 to 5. Maybe it's the SCSI bus under win+r, msinfo32, System Summary, Components, Storage?

I hope this helps.

In my case the problem was solved when I disable the Hot plug in the BIOS, in HOT PLUG mode the mechanical hard drive is detected as External Hard Drive so windows 10 1809 do not permit the creation of the pagefile in that drive. apparently it is a new directive in windows 10 1809 because in 1803 it was not necessary to change the information in the BIOS.

in this post you can follow the instruction for those who don't have this option in the BIOS.

I hope this information helps you.

Hi Mahfoud,

This issue is not related to the blog post that you shared. 

Can you please run the following from an admin command window and share the output?

1. reg query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management"
2. dir /a c:\pagefile.sys
3. dir /a d:\pagefile.sys

New in 1809, page file doesn't get created on "portable drives". It's possible that the storage controller is incorrectly reporting the drive as "portable" causing Windows to not use the drive for page files. 

What's your storage controller (win+r, msinfo32, System Summary, Components, Storage) ? If you can share screenshots again, that will be great.

Thanks!

My PC has RAM 8 GB. And I want to move pagefile.sys from drive C to drive E. Because my drive C almost full. So I set up custom size page file in drive C to minimum size or no page file and use "System manage size" in drive E. but my setting not effective in Windows 10 Pro this version. In previous versions of Windows 10 Pro, I can move page file from drive C to another drive.

Hey Cut. I'm Greg, an installation specialist and 9 year Windows MVP, here to help you.

That Custom size you're attempting is way too low. The minimum size should be 1.5 times the amount of RAM you have.

See this guide for examples: https://www.tomshardware.com/news/how-to-manage...

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
