Microsoft: PrintNightmare now patched on all Windows versions

What is PrintNightmare?

The Microsoft Windows Print Spooler service has discovered a vulnerability known as PrintNightmare (CVE-2021-34527). It has the potential to allow malicious cyber actors to seize control of a targeted system. On account of its functionality, it is primarily used on Domain Controllers. Therefore, a malicious user might target a remote Windows computer and insert DLLs that a regular Windows user would then be able to execute as SYSTEM on the Domain Controller.

If you’ve used a Windows computer for any length of time, you’ve probably encountered a printer problem or two. Depending on your version of Windows and the printer model, the troubleshooting process can vary widely. But one universal headache remains: if your printer is set to print in the middle of the night (or any other ungodly hour), you may hear what sounds like a small child screaming in agony.

The noises are coming from your printer, which is attempting to print by emitting an extremely high-pitched frequency. It sounds like someone is getting tortured, but it’s actually just the result of frequencies that humans can’t hear, but most modern computers and mobile devices can detect that. Even so, this disturbing sound has been nicknamed “the screech” because it sounds exactly like that. Read More >

How to Disable the Windows Print Task

In Windows 10, you need to find the “Printers and Scanners” icon in the Control Panel. Click on it and then click on “Devices and Printers,” where you will see a list of printers. Right-click on the printer making the noise and select “Printing Preferences.” On the first tab, titled “General,” you should find an option for disabling printing at night. Select this option and set the time range of 12:00 am to 6:00 am. You can also disable printing during holidays or weekends if desired.

Microsoft: Change your printer’s scheduled task

One strategy you can use to remedy this problem is by changing your printer’s scheduled task. This will allow you to change the time at which your printer begins printing. You’ll be able to stop the screeching and give yourself some peace and quiet in the process! To find your printer’s scheduled task, follow these steps: 1) Open Control Panel, then search for “printer tasks” 2) Right-click on the printer you want to make changes to, then select “properties” 3) Click on the Schedule tab, then change the timing of when it prints 4) Click “OK” 5) Close Control Panel.

Microsoft: Update your Windows version

As it’s often called, the screech was originally a result of printers emitting inaudible frequencies. But over the years, all versions of Windows from Vista onwards have been programmed to emit sounds that are audible to humans when printing. These sounds are typically human-like screams and birds chirping.

There is no official explanation for why these sounds were chosen, but it’s presumed that they were designed to alert users who may be in another location. But the problem is, if you’re using an older version of Windows (earlier than Vista), then your device won’t emit any sound when printing, and you might not even know your device is making a sound at all.

Microsoft has released a patch that updates the operating system to include these “screaming or chirping” noises when printing to avoid this issue with an old operating system. This means that anyone still using an older version of Windows can enjoy the peace and quiet again too!

Microsoft: Manually set the time for your printer to print

Microsoft has a solution for this problem. You can manually set the time for your printer to print by following these steps: * Open the Control Panel and click on “Printers and Other Hardware.” * Right-click on your printer icon and select “Properties.” * Select the “Job Settings” tab, then scroll down until you see “Start printing at.” If you don’t see this option, your printer is a Cloud Ready Printer that automatically determines the time. * In the box labeled “Start printing at,” select a time that is suitable for you. * Click “OK” to save your new settings.
