Windows 10: How to access winre.wim?

Where in a Windows 10 installation is winre.wim stored? If it's stored in the EFI system partition, how can I access it?

I'd like to use it to build backup software (Macrium Reflect) rescue media.

How do I (mount and) copy the contents of (hidden) WinRE?

I have a WinRE partition at the end of my SSD and I want to move it down following the Win NTFS system partition so I can install Linux in the fourth position.

This SuperUser suggests copying the contents of WinRE.

I would recommend assigning a drive letter to it and obtaining a copy of the WinRE.wim file. You'll need it to move the recovery environment somewhere later. You can obtain a copy of this file in other ways, but it will be easier just to get it ahead of time.

How to make a hidden partition visible says how to launch Disk Management to access Admin Privileges. But the steps say to right click on the hidden partition, but Disk Management never give me anything more than “help” popup.

Compacting a wim file?

Sorry, no idea where to put this. I just recently learned how to use dism. I use it to slipstream all hotfixes and ie10 ect into an AIO install disc. The problem is, it creates a huge install.wim after 8 index mounts and slipstreams. Considering all 8 images use the same darn wim and files, don't know why it has to increase the wim size by 1gig. Either I need to figure out how to use the same wim.install file for all indexes, or I need to compact the wim file which is now 4gbs with ie10 and all updates to April. Any way to do either?

 

Convert ESD file to WIM using DISM in Windows 10


I just needed to do it to grab the Winre from a newer ESD ISO(the official one from the release date, instead of the one I had the Friday before).

Just so others know, you need to do these steps if you wish to replace missing or corrupt Windows system files and libraries(.dll)(not so sure about replacing folders though).

*InfoIt must come from a Install .wim and not .esd
