If a Microsoft Windows system is running the
Microsoft Defender
Firewall,
firewall software that comes with Microsoft Windows systems, you can
check on whether connectivity is allowed on a particular
network
port from a
command-line
interface (CLI) using
PowerShell. You can determine whether the Windows Firewall is active on a
system from a command prompt
using the command netsh advfirewall show
currentprofile. If the value of "State" is "ON", then the Windows
Firewall is active on the system.
C:\>netsh advfirewall show currentprofile Domain Profile Settings: ---------------------------------------------------------------------- State ON Firewall Policy BlockInbound,AllowOutbound LocalFirewallRules N/A (GPO-store only) LocalConSecRules N/A (GPO-store only) InboundUserNotification Enable RemoteManagement Disable UnicastResponseToMulticast Enable Logging: LogAllowedConnections Disable LogDroppedConnections Disable FileName %systemroot%\system32\LogFiles\Firewall\pfirewall.log MaxFileSize 4096 Ok. C:\>
You can check on whether the firewall is permitting connectivity on a
particular network port, e.g., TCP port 3389 for the
Remote Desktop
Protocol (RDP), from a PowerShell prompt, which you can obtain by
typing powershell in the Windows "Search" field at the bottom
of the screen and then clicking on Windows PowerShell when you see
it returned by the search function. At the PowerShell prompt, you can issue
the command Get-NetFirewallPortFilter | Where-Object { $_.LocalPort -eq
3389 } | Get-NetFirewallRule. If you wished to check on whether
firewall connectivity is permitted for some other protocol, substitute
the port used by that protocol, e.g., port 22 for
Secure Shell (SSH)
connections.

When I sat down at a system running the Microsoft Windows 11 operating system on Saturday, I saw a message stating that Microsoft Paint had updated itself automatically. I had at least a dozen Paint windows open where I had posted screenshots over the past week for things I wanted to check later. I had not saved those Paint windows; I had anticipated going through them on Saturday, extracting information I wanted to keep from some images and then closing the windows and saving others. But I found the update had just closed them all without any prompt asking whether I wanted to save them and without saving the images. So I lost all the information from them irretrievably. Certainly, I should have saved the images in those Paint windows or used some other graphics application that automatically saves the contents of windows for that application or at least won't automatically update itself without saving any unsaved work, but I'm still irritated at the mindset of Microsoft developers regarding not caring about the impact to users if users have unsaved content in Microsoft applications, in addition to being irked with myself for not saving the information. I do use Paint a lot for simple graphics tasks, such as cropping and resizing screenshots, and I don't want it updating itself without warning when that may lead to a loss of information I haven't yet saved. You can determine when a Microsoft Store app was last updated and turn off automatic updates for apps obtained from the Microsoft Store, though you have to turn off the auto update feature for all apps, since there is not a way to do it only for a particular app, such as Paint.
