+### Optional WinSSH Configuration
+
+When using the WinSSH communicator, you may run into an issue where a PowerShell
+command can't display a progress bar. A typical error message might look like:
+
+```
+Win32 internal error "Access is denied" 0x5 occurred while reading the console output buffer.
+```
+
+In order to prevent this, we recommend setting `$ProgressPreference = "SilentlyContinue"`
+in your box's PowerShell profile:
+
+```
+if (!(Test-Path -Path $PROFILE)) {
+  New-Item -ItemType File -Path $PROFILE -Force
+}
+
+Add-Content $PROFILE '$ProgressPreference = "SilentlyContinue"'
+```
