Windows 10: questions about recovery concerning the inre.wim file location

I very clearly have two files reagent.xml and a large sized hidden file called winre.wim in the recovery folder under windows > system32.
1) Is this the windows image file for refreshing of windows or reinstalling windows ?
2) When this happens, does windows get refreshed or reinstalled to the latest build (I have build 1803 currently) or have I to use windows update to get back to build 1803
3) If this is the system image recovery file in Windows > system32>recovery, then what would I find on a recovery partition of almost 900 Mb on my laptop?

Thank you

:)

 

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?

 

Compacting a wim file?

Actually it turns out the answer is the dism that comes with Win8. Using the new Export-Image command, and a simple batch file, was able to compress my AIO wim by several hundred mbs.

Hi,

The WIM file format is almost the same as ISO files which is an image of a disc. These file types are usually opened by 3rd-party software which will enable your computer to mount the disk image for installation. Your question on how to install it is best
