There is a lot of disk free space on C: but you don't have the Recovery files.
I suggest you do a Repair Install Windows 10 with an In-place Upgrade

I could not figure out how to upload a zip file here, so I placed the logs and zip file on my dropbox:

Dropbox - Ten Forums Logs - Simplify your life

Everything found 0 files when searching for winre.wim

"The installation media (ex: ISO or USB) must be the same edition and same or newer build as your currently installed Windows 10. If it's not, then the repair install will fail."

Since the vendor didn't supply recovery media, I do not know whether the install media I created a few months back would even work with this version.

Open a CMD window as administrator and type:
Winver
It will show what version is installed.
You can download Win 10 iso Ver 21h2 using MCT
Next, right click on the iso and select mount. It will create a virtual DVD. On it, run setup.exe and it will begin the Repair install.

First scannow:

Code:

Windows Resource Protection found corrupt files and successfully repaired them.

Second scannow:

Code:

Windows Resource Protection did not find any integrity violations.

It is not necessary to have a recovery partition if you create a bootable Windows 10 iso and use its Windows recovery partition.
Also the computer appears to have available Macrium ram disk to repair boot problems.

If you want to create a Windows recovery partition to have "belt and suspenders" then you can.
The in place upgrade repair is an easy method in which Windows recreates it.

All of the drives are MBR.

If the in place upgrade repair is successful the partition structure will appear as in this link: (see partition layout)
https://docs.microsoft.com/en-us/win...iew=windows-11

If the computer had BIOS: UEFI / GPT then you could create the partition layout in this link:
https://docs.microsoft.com/en-us/win...iew=windows-11

To perform an in place upgrade repair you can download the iso to the desktop or create a bootable Windows 10 iso.
Both options are available via these links:

Create Bootable USB Flash Drive to Install Windows 10
Download Windows 10 ISO File
https://www.microsoft.com/en-us/soft...load/windows10

Before performing the in place upgrade repair please perform these steps uninstall any of these non-Microsoft software
a) antivirus
b) firewall
c) drive encryption

If possible, you can perform the in place upgrade while other drives have their cables detached or while the drives have been uninstalled.

With the recovery environment disabled winre.win should be in the C:\Windows\System32\Recovery folder. When the recovery environment is enabled it is moved from there to the recovery partition. There is only ever one winre.wim file, where it's located depends on whether recovery is enabled or not.

Now if the recovery partition is deleted so that C: can be expanded while the recovery environment is still enabled, then the only copy of winre.wim will be lost. If you have the install ISO or USB for the version of Windows that is installed, then you can get another copy of winre.wim from it.

You need to open the Install.esd (or install.wim) from the Sources folder on the iso/usb. You can use 7-zip File manger to do this. Copy it and put it in c:\Windows\System32\Recovery\ and you will then be able to enable recovery environment.

This is possibly easier, and certainly quicker than an in-place repair install. Both would work though.

The method that Bree commented on I'd like to view.

In case there are any problems the in place upgrade could be the backup plan.

The iso can be downloaded to the desktop.

A separate recovery partition can be created immediately to the right of the C: partition with a few administrative command prompt commands.

This should make the computer maker's splash screen appear during bootup and give you the time to start tapping the relevant key to get into its Bios/UEFI or the relevant key to get into its Boot options menu.
The relevant keys should be identified in the computer manual & on the maker's support site. They might also be identified onscreen while the splash screen is displayed.

2 Is your computer booting into Bios or UEFI mode?

Looks like I have 21H1. Are the other numbers important to be matched the same as well?

You have Win10 21h1.
MCT will download Win10 21h2

A repair install will also do an upgrade

Will it mess up the week's worth of setting up and debugging problems on IIS to get my web sites running? Or is this upgrade fairly transparent?
