Same here no any video output when at booting only red flash.
Now im trying to download the same as above, the newest one doesn’t work.
–Edit–
I see the WoR give some error in the logs:
2020-03-23 22:45:39.7888 [info] Verifying the boot package…
2020-03-23 22:45:40.2313 [warn] The server returned an error while checking the MD5 hash of the remote boot package.
Sees like the boot package is corrupted i will try it another day with a other browser.
When I followed mscooke69’s instructions, I had to manually recopy over the v1.5 firmware into the boot directory. When I checked the config.txt after flashing with WoR, it didn’t match the config.txt from the firmware zip file.
That explains a lot why its not booting, i will try it again thanks for sollution!
Thanks, Windows is now starting 
Yes I think I mentioned that in a later post
I have expanded what worked for me, including some of the actions in later posts. Hopefully this will give some guidance to anyone else looking to try.
Connectivity wise I have a USB-C in/out hub, with a normal USB hub connected to that. The second USB hub has my USB wireless keyboard/mouse dongle and a USB ethernet port. The current capability does not enable the on-board USB ports, ethernet LAN
Then as Marcinoo97 detailed
Run the WoR against your storage device
Use the ARM image from Step #3
Use the Drivers as a Zip from Step #4
Use the extracted UEFI from Step #1
The config.txt for me worked the first time, but then I couldn’t seem to get it to work, so I merged the two files from the WoR and UEFI.
On the screen where you have the boot options, merge the existing with those in the config.txt in the UEFI
my BootConfig is :-
arm_control=0x200
enable_uart=1
armstub=RPI_EFI.fd
disable_commandline_tags=1
disable_splash=1
arm_64bit=1
enable_gic=1
disable_commandline_tags=1
device_tree_address=0x1f0000
device_tree_end=0x200000
device_tree=bcm2711-rpi-4-b.dtb
dtoverlay=miniuart-bt
Open to Command Shells as Admin
Command Shell #1
Diskpart
List Disk - Find your storage device
Sel Disk n (n is your storage
Sel partition 1
assign letter T
Command Shell #2
bcdedit /store T:\EFI\Microsoft\Boot\bcd /set {default} recoveryenabled no
bcdedit /store T:\EFI\Microsoft\Boot\bcd /set {default} truncatememory 0x40000000
Explorer
Copy the contents of the extracted UEFI except for the config.txt to the T Drive
Command Shell #1
remove letter=T
You can now take the SD Card out and insert into your PI
Connect your PI up, you will need a USB-C in with a USB-C out and a normal USB out to be able to connect a keyboard/mouse or a USB hub. I have a USB Ethernet adapter in my hub
Switch it on and you should get a Raspberry splash screen.
Press ESC on that and go into the Device Config, set the speed to Max.
Save
Goto Boot Manager and select the Boot Device
Save and restart, then wait … and wait … and wait … press the enter key, might help.
Eventually you get the Windows setup screen. If you have everything plugged in and its working you should be able to complete the setup. If you haven’t then you might need to fiddle with the cable combinations.
Still stuck at 1Gb but its up and running and on the network. My SD card is maxed out, the performance is terrible but at least I can have a fiddle now and see if I can get any further
Thanks to Marcinoo97 and everyone else who has contributed
Hopefully that will help to give you a bootable Windows 10 on your PI4 and I haven’t missed too much out this time.
Thx this works for me the 1GB is terrible but it’s starting up!
Its not a desktop or a decent laptop, but then its not a fully enabled solution yet. If the memory can be opened up as well as the on-board USB ports then it could have its uses, but until then its not much more than a thing to try and fix. Adding an SSD helps with the performance, but its still a limited solution.
How can I boot from SD card? And can I use my RPI4 touchscreen monitor with it?
Try the steps above from mscooke69 for installing W10 on a Rapsberry Pi4.
I don’t have tested a touch screen i think its not working but you can try it.
The performance is also a issue with a USB-C dock and mouse there is some very very slow input.
The reason for this problem is the 1GB RAM and SD card performance.
I have heard from UEFI developer that any video output will work as long as it can display rainbow splashscreen but it might require some changes to config.txt, Your touch input has small chance of working in Windows as Windows lacks drivers for it. Try and report back!
New UEFI (v1.7) has 1.5GHz cpu speed as default so people will no longer complain that their rPi is stuck at 600Mhz.
and that is no longer needed with newest UEFI (v1.7)
mscooke69
could you elaborate guide on how to install … on the diskpart part… i dont understand
currently i am trying to deploy windows 10 arm64 for my final year project.
Which part don’t you understand?
step 6 are done after finishing step 5?
this one means we cannot use the device usb ?
No, there are no drivers at present to use the on-board ports, the best you can do at present is connect a USB hub to the USB-C input and run through that. I have my wireless keyboard/mouse dongle, ethernet adapter and SSD running though it so its possible, but less than ideal. The SSD makes a big difference but limited on the swapfile useage
do you mean use the power input? how to boot up the pi with hub ?
sorry i’m a litle bit blurred…
I have used a usb C hub with power delivery and USB ports for keyboard mouse.
There is such one USB-C port which you can use 
I think a usb C hub with bootable USB 3.0 Disk make such a different speed boost or is it not compatible yet?
