Fix Windows 11 Black Screen Error

The third time is charm saying goes but not when we are talking about Microsoft. Print spooler is again in focus, in a bad way. This is the third print spooler vulnerability to emerge in just five weeks. While a critical flaw was originally identified and patched in June, a similar flaw came to light shortly after and was subsequently patched (with mixed success). Microsoft is once again advising its customers to disable Windows print spooler after a new vulnerability that allows hackers to execute malicious code on machines has emerged. While a patch fixing the flaw will be released in due course, the most effective workaround currently on the table is to stop and disable the print spooler service entirely.

"An elevation of privilege vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights."

Stop this service right away or you are risking a potential attack.

1. Press ⊞ WINDOWS + X to open the hidden menu
2. Click on Power Shell (admin)
3. In Power Shell type in the following command to check if spool service is running: Get-Service -Name Spooler followed by ENTER
4. If spooler service is running type in the next command to stop it: Stop-Service -Name Spooler –Force and press ENTER
5. Then follow with this command to disable it at startup: Set-Service -Name Spooler -StartupType Disabled followed with ENTER

That’s it, we hope a patch will come soon for all the people that are using network printing and indeed need this service running in order to do work.

Referenced Memory at - What is it?

0x Referenced Memory at 0x is an error code that occurs when the random memory addresses conflict. This error causes running programs or browsers to crash. Referenced memory at error code is considered as a service violation error. It is displayed as the following:

“The instruction at 0xf77041d24 referenced memory at 0×00000000. The memory could not be read.”

Solution

Error Causes

The ‘referenced memory at’ errors is either triggered by:

• Hardware failure
• Problems with the RAM and the registry

Hardware failure may result if the driver is not installed properly. The problems in the RAM indicate registry issues that occur due to data overload in the hard disk and poor PC maintenance. The registry saves all the information and activities you perform on your system on the hard disk. This includes the junk files, temporary files, invalid registry entries, and files of both installed and uninstalled programs.  These files accumulate and take over a lot of RAM space. Also, the referenced memory at error can be considered to be a form of memory leak where unknown third-party software can take up the memory space that has been reserved for a particular program. For example, if you have toolbars and add-ons installed in your browser, it can also lead to invalid registry storage in the registry. If you don’t clean the registry, these unnecessary files can overload your data and lead to hard disk/RAM damage and corruption triggering obscure error messages like referenced memory at error.

Further Information and Manual Repair

Referenced memory is a critical error; if not resolved it can lead to serious PC damages like a system failure. To avoid this, it is advisable to fix it right away. Here are a couple of ways to repair this issue on your system:

Cause: Hardware Failure

Solution: If the referenced memory at error is generated due to hardware failure then to resolve this error you must reinstall the driver that has caused the error to appear. Let’s say if the error pops up because of the printer driver, reinstall it. For re-installation of the driver, simply go to the control panel and click on the Device Manager option. Once you click it you will see a detailed page with a list of devices. Now click on the printer (the problematic driver in this situation) to reinstall the driver software. Double click on it to open the properties dialog box and then click the driver tab and update the driver. Once you have updated the driver, try using the printer. Check if it works. If it works and the referenced memory at the error code does not appear on the screen, this means the problem was with the hardware. However, if the error still pops up then this means the problem is deeper. It’s related to the registry.

Cause: Problems with the RAM and the registry

Solution: If the problem is with the RAM and the registry, then it is advisable to download Restoro. Restoro is a new, next-generation, and highly functional registry cleaner.

What is Error Code 37?

Error Code 37 is a Device Manager Error Code that you may come across when you are unable to use an installed hardware device on your PC. It will pop up on your screen with the following display:

“Windows cannot initialize the device driver for this hardware. (Code 37)”

If you receive the above message, it means that your operating system was unable to acknowledge the drivers for a particular peripheral device.

Solution

Error Causes

Error Code 37 mainly occurs due to device driver corruption. However, there are other factors that can trigger this error code, some of which are the following:

• Missing device drivers
• Out-of-date device drivers
• Presence of malware or spyware in the system
• The particular device is not compatible with your PC

Device driver corruption or other data corruption is not uncommon and part of everyday PC use.

From an installation gone wrong to an unexpected shutdown, commonly generated data errors are considered the main culprit behind error codes.

Further Information and Manual Repair

Just like most PC error codes, Error Code 37 isn’t that difficult to get rid of. There are many DIY methods you can try to have your PC running smoothly in no time. Here are a few methods to resolve this issue:

Method 1: Restart your PC

It is possible that the display of the error code is merely due to a temporary issue with your peripheral device and not anything serious.

Therefore, the quickest and easiest method to solve the error code 37 is to simply restart your PC.

Method 2: Scan for Viruses

If restarting does not do the trick, a quick scan for viruses and removing them is another simple method you can follow to fix your PC.

Since the error code is due to corruption of data, viruses such as malware or spyware create error in your PC’s registry and eliminating them can help restore some of the corrupt data, which also speeds up your PC.

As in previous Windows 10, inside Windows 11 also when you press the ALT + TAB key combination you will get a preview of all running applications along with all Browser tabs so you can go through them and pick the one you want to switch to. Alto, I personally am a big fan of alt-tabbing, I must admit that I am not a big fan of having multiple browsers tabs on screen when I do press key combo. Luckily there is a very easy way to turn this feature off. Turning browsers tabs thumbnails off

1. Press ⊞ WINDOWS + I to open settings
2. Click on System in the sidebar
3. Scroll down and select Multitasking
4. Find Alt + Tab section and click on the drop-down menu
5. Pick Open Windows Only
6. Close settings

Now when you press the ALT + TAB key combination you will still see your browser but only an active tab in it instead of all tabs as different preview thumbnails.

The latest security vulnerability was discovered inside both Windows 10 and Windows 11 letting any user access admin privileges inside the operating system. This can, of course, be used by a potential attacker to get full control of the system. The problem lies in Microsoft's security rules assigned to the Windows Registry and the Security Account Manager. Both for some reason have reduced restrictions allowing any local user to fully access the files without administrator privileges. The problem is even more amplified if we think about Security Account Manager which includes all account data including the passwords of all users using the same PC. This can provide a potential attacker with all information and let them log on into the administrator account for full control. Microsoft is aware of the matter and is tracking it with code CVE-2021-36934, and includes a complete workaround for the issue, which includes restricting access to  %windir%\system32\config and deleting any restore points or Shadow volumes that were created before that point until the hole is plugged with an official security patch.

Black Screen During Installation - What Is It?

Many are upgrading their OS to Windows 10, however, it’s not always smooth sailing because users have been reportedly experiencing different bugs including Black Screen after a successful update.

One common issue in installing Windows 10 is the appearance of a black screen after installation. This usually occurs when the user restarts the computer. Initially, there will be a black screen only appearing on the monitor. There are also cases where a mouse cursor is present, while some cases have no cursor at all.

Not only that, it seemed that you’ve lost all your desktop icons when experiencing this bug.

Solution

Error Causes

Just like the other bugs experienced by Windows 10 users, booting to a black screen has reasons. Before you even try to look for the solution, you first have to determine the cause of the error, in this case, the error would be black screen when booting.

• Error on external devices such as printer or mouse.
• Having outdated display/video drivers that normally result in black screen when OS is updated.

If error messages are left unsolved, you may encounter other Windows 10 related issues such as error code 0xc0000142. 

Further Information and Manual Repair

Before you even think of upgrading your OS to Windows 10, you need to know that there are specific system requirements and specifications to be able to successfully update your operating system.

• Minimum of 1 gigahertz (GHz) Processor
• Either 1 (GB) (32-bit) or 2 GB (64-bit) Ram
• You need at least 16 GB of free hard disk space
• A Microsoft DirectX 9 graphics device or later with WDDM 1.0 driver graphics card
• 800 x 600 display

If you were having some problems with your internet connection and you tried to run the Internet Connections troubleshooter but it displays an error message instead that says, “The default gateway is not available”, read on as this post will show you what you can do to fix this error. The first thing you can do to fix this error is to restart your computer and then try to run the Internet Connections troubleshooter again. However, if you still see the same error message, then you might want to troubleshoot the problem further. You can try to install the Network driver or reinstall the Network adapter drivers. You could also verify the power saving mode or reset TCP/IP as well as disable the Firewall temporarily.

Option 1 – Try installing the Network driver

The very first thing you can do to resolve the error is to install the network driver. It is a common solution to this kind of problem and most users encounter it right after a fresh installation of Windows 10. So if you have done this, then you need to install the network driver so that the network adapters can start working. You can find the network driver in the motherboard CD. On the other hand, if you are using a laptop, you might have to use another computer or mobile to download the network driver from the manufacturer’s website.

Option 2 – Update the Network Adapter drivers

If the first option is not applicable to you since you already have network drivers in your computer, you might want to update the Network Adapter drivers by following these steps:

• Tap the Win + R keys to launch the Run window and then type in the “msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand them.
• Then right-click on each one of the Network drivers and update them all.
• Restart your PC and see if it helped in fixing the BSOD error.

Note: If updating the network drivers didn’t help in fixing the “Windows could not find a driver for your network adapter” error, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

You could also try to reinstall the network adapter driver, refer to these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Option 3 – Try to verify power-saving mode

If you are using a Windows 10 laptop, then you should know that the Power Options panel plays an important role. So if you’re getting an error in your laptop, you have to check some settings that are related to the Power Saving mode. To do so, follow these steps:

• Open Control Panel and go to Hardware and Sound and click on Power Options.
• Next, click on the “Change plan settings” option of your selected plan and then click the “Change advanced power settings” option.
• After that, you should see the Power Options window, and here, expand the Wireless Adapter Settings and Power Saving Mode.
• Now make sure that the Maximum Performance option is selected. If it’s not, select it and save the changes you’ve made.

Option 4 – Try to reset the TCP/IP

As you know, the TCP/IP or the Internet Protocol is the most important thing if you want to use the internet on your computer. That’s why if it ends up getting corrupted, you need to reset the TCP/IP to fix the problem. To reset TCP/IP, refer to these steps:

• In the Windows start the search, type “command prompt” and right-click on Command Prompt from the search results.
• Then select the “Run as administrator” option to open Command Prompt with admin privileges.
• After that, execute this command: netsh int ip reset resettcpip.txt
• Once it’s done, exit Command Prompt and restart your computer and then check if the error is now fixed.

Option 5 – Temporarily disable Firewall

On the other hand, the error could also be due to the Firewall software installed on your computer. Thus, disabling them or any security software installed on your computer is always a good idea you can try when you’re not able to access the shared drive on your computer. There are times when you encounter problems like the error “The default gateway is not available” due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program and Windows Defender Firewall for the meantime and check if it fixes the error or not
