If you have a feature request, please post to the UserVoice.

Important: When reporting BSODs or security issues, DO NOT attach memory dumps, logs, or traces to Github issues. Instead, send dumps/traces to secure@microsoft.com, referencing the GitHub bug number. Ideally, please configure your machine to capture minidumps, repro the issue, and send the minidump from "C:\Windows\minidump".

• Your Windows build number: (Type ver at a Windows Command Prompt)

Microsoft Windows [Version 10.0.17017.1000]

$ uname -a

• What you're doing and what's happening: (Copy&paste specific commands and their output, or include screen shots)

In apt-using distros, the command /usr/lib/update-notifier/apt-check is used to show the number of available updates and the number of available security updates, in STDERR and normally in 0;0 format, but there's a flag for human readable.

With WSL, I get
$ /usr/lib/update-notifier/apt-check 2>&1
E: Unknown Error: '<class 'PermissionError'>' ([Errno 1] Operation not permitted)

• What's wrong / what should be happening instead:

$ /usr/lib/update-notifier/apt-check
0;0

• Strace of the failing command, if applicable: (If <cmd> is failing, then run strace -o strace.txt -ff <cmd>, and post the strace.txt output here)
