The latest Winre.wim is over 700 MB, and its only going to get bigger. 1 GB or less is not enough.
I realize some users have space issues, but some do not.
That's the script I use, always with the most recent ISO with updated boot files from UUPdump.

Works nicely with more than one drive as well :-)

You can't use Macrium's base WIM, as it's severely outdated. You need to tell Macrium
to use the most current WinRE.wim located in your recovery partition.
Open an elevated command prompt. Enter:
reagentc /info
If enabled:
reagentc /disable
This places the most recent winre.wim into...
New SkuSiPolicy and WinRE, all boot media updated.
