WinGet is down because Microsoft let a security certificate expire
Microsoft only recently updated its Linux-style package manager for Windows, WinGet, adding support for zip files. But at the moment, fans of the tool are reporting that it is not working, with many seeing "InternetOpenUrl() failed" errors.
The problem stems from something of an embarrassing SNAFU for Microsoft. The company appears to have forgotten to renew the SSL certificate for WinGet.
