Microsoft allows you to freely download Windows 10, and burn the write the image to an 8GB USB memory-stick, or burn the image to a dual-layer DVD.
Then, as described earlier in this thread, you can "browse" the media.
2. How can I find the .wim file on one of them?
From a Windows command-line on one of them:
a. CD \
b. DIR /S /A *.win > C:\Where-is-it.txt
[This will take a while, without writing anything to the screen.
When it completes:
c. Notepad C:\Where-is-it.txt
[Look for the correct folder & correct filename.]
Copy the correct file to an external USB memory-stick, for physical transport to your computer. Copy the file into a new folder on your computer.
3. Do I need to copy it to my recovery partition, and how do I do this?
The REAGENTC command can specify the "path" of that "new folder".
Maybe, consider NOT doing any of the above, unless you fully understand what you are trying to achieve. Instead, just accept the very-minor "risk" of NOT applying the update, which would leave your Windows only slightly more "risky" than it currently is.
After October 14, 2025, Microsoft Support for Windows 10 will stop, forcing you to upgrade your computer to Windows 11. Installing Windows 11 is best done on a brand-new, and empty, disk-drive. In 2025, what you install will include this problematic update, thus relieving you of any issues with this update.
Your current disk-drive will be out-of-warranty by October 2025, and should be "retired", set aside, and labelled for what it was. In 2026, you will have the option to reconnect the old disk-drive, if you have a need to boot into Windows 10 "one last time".
