Windows 10 comes with it's own curl but seems to be behind on the curl updates. So I wanted manually update curl to latest version which is curl 8.17.0 at time of writing. Get latest curl for Windows
Firstly, delete curl.exe at C:\windows\system32 and C:\Windows\SysWOW64, these were stuck at version 7.52.0. You'll need take ownership of the file, with your username.
Then find what default curl.exe is being used in the command line cmd.exe.
Execute where curl.exe
So, we see chocalatey is now the source of curl.exe command, it's 1st on the resultant list.
Upgrading chocalety, using following command
choco upgrade chocolatey choco upgrade curl
Upgrade completed with proper shims.
If you don't have chocalety, then you can manually copy files from curl 8.17.0 zip folder /bin copy these files:
curl-ca-bundle.crt
curl.exe
libcurl-x64.def
libcurl-x64.dll
trurl.exe
to next directory in the list.
And now curl is upgraded in cmd.exe when you launch it.
