Specified service does not exist, 0x80070424

A few days ago we celebrated fixing of months-long PrintNightmare vulnerability by Microsoft, sadly a new bug and issue have been found. Firstly discovered Microsoft stated:

A remote code execution 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.

A few days ago, Microsoft officially released a patch that was supposed to finally fix it. As you might recall this vulnerability was present for quite some time, Microsoft's solution after a long struggle was to elevate certain privileges to administrator account only and remove user accounts from managing printers. It complicated things a little bit but it was stated payoff was worth it. The new issue now is that on a system that already had accounts created and set, old accounts still can hijack the system, patch issues address only accounts that are created after the fix is administrated, old ones can still do whatever they want. Once again of course Microsoft has stated that until it is again resolved you should again disable the Print Spooler service as a temporary workaround.

There are times when an IT admin has to set up multiple IP addresses to the same network adapter. Setting up multiple IP addresses in scenarios like hosting various SSL sites, speed up traffic exchanges can help in avoiding being blacklisted in the SPAM filters, and so on. So in this post, you will be guided on how exactly you can assign multiple IP addresses to the network adapter in your Windows 10 computer. There are several ways to assign multiple IP addresses in a network adapter. You can do it using the Network Adapter settings or using the Netsh utility, as well as the Windows PowerShell utility. To get started, refer to each one of the options provided below.

Option 1 – Assign multiple IP addresses via Network Adapter settings

• Go to Settings first and from there, select Network & Internet, and then click on the Change adapter options. This will show you a list of both the physical and virtual network adapters in your computer.
• Next, double click on the Ethernet adapter where you want to assign the multiple IP addresses and then click on the Properties button.
• After that, you should see the Ethernet properties where you have to select the “TCP/IPv4” or “TCP/IPv6”.
• Once done, click on the Properties button and then select the “Use the following IP address” option under the General tab.
• Now you have to add an IP address, subnet, and default gateway to the network adapter and then click on the Advanced button.
• This will open the Advanced TCP/IP settings where you have to click on the Add button so you can add an IP address. From here, you can keep adding multiple IP addresses to the network adapter. You also have the option to add multiple gateways or DNS IP addresses.
• Once done, if you execute the “ipconfig” command, you should see all the secondary IP addresses listed.

Option 2 – Assign multiple IP addresses using the Netsh command

Another way to assign multiple IP addresses to your network adapter is via the Netsh command.

• In the Start Search, type “command prompt” and from the search results that appear, right-click on Command Prompt and then select the “Run as administrator” to open it with admin privileges.
• If a User Account Control or UAC prompt pops up, just click on Yes.
• After that, run this command: Netsh int ipv4 add address name="Local Area Connection" 192.168.100.100 255.255.255.0 SkipAsSource=True

Note: You have the option to set “SkepAsSource” since it depends on your needs using the Netsh command. When it is configured as true, the IP address won’t be used by the OS for outbound connections.

Option 3 – Assign multiple IP addresses via Windows PowerShell

• Tap the Win + X key combination and click on the “Windows PowerShell (Admin)” option.
• After opening Windows PowerShell as admin, use the NetIPAddress command so you can add more IP addresses. Execute this command: Get-NetIPAddress | ft IPAddress, InterfaceAlias, SkipAsSource
• Next, assign an IP address to a network adapter by executing this command: New-NetIPAddress –IPAddress 192.168.100.100 –PrefixLength 24 –InterfaceAlias “vEthernet” –SkipAsSource $True
• Now to modify the “SkipAsSource” parameter, use this command: Get-NetIPAddress 192.168.100.100 | Set-NetIPAddress -SkipAsSource $False

In today's modern world many households have internet access, most of the connection nowadays is done via Wi-Fi or wireless but there is a high probability that you have also a few devices connected via cable. There are of course many disadvantages and advantages between cable connection and wireless connection.

The main advantages of a hard cable connection are of course faster speed and stability compared to Wi-Fi. But if we look into the cables themselves there is also a big difference between them. Not all cables are the same and quality as well as speed vary a lot between them. Choosing the right cable is essential in order to make a maximum of your internet and we have some great tips and explanations of what cables do so you can make the right choice and enjoy your full internet potential.

Not all cables are the same

Cheap cables and expensive ones are not the same no matter what everyone tells you. The old proverb you get what you pay is true and more expensive cables will be made from better materials and will have a higher transfer rate.

Quality network cables are separated into different categories with proper markings and when buying one you should always look for these markings on the cables themselves, do not buy cables that do not have markings since they will often provide lower transfer rates or will not be shielded from outside influences resulting in packet drops and instability in a network.

Categories and what they mean are:

• Cat-5 with a maximum speed of 100Mbps, typically unshielded.
• Cat-5e with a maximum speed of 1Gbps, available in both shielded and unshielded varieties.
• Cat-6 with a maximum speed of 10Gbps for runs under 55 meters (around 180ft), available in both shielded and unshielded varieties.
• Cat-6a with a maximum speed of 10Gbps, shielded.
• Cat-7 uses a proprietary GG45 connector rather than the standard RJ-45 connector seen on other cables for speeds of 10Gbps, shielded.
• Cat-8 with a maximum speed of 25Gbps (Cat-8.1) or 40Gbps (Cat-8.2) at a distance of around 30 meters (around 100ft), shielded.

Unless stated, these standards are typically rated at their quoted speeds for a run of around 100 meters (around 330 ft) and use a standard RJ-45 Ethernet connector. Each generation of cable is designed to be compatible with the generations that came before it, so it’s possible (for example) to use a Cat-6a cable with a router that only supports speeds of 1Gbps.

Shielded cables

When purchasing higher quality cable you might not be able to choose if you have shielding or not since some standards like Cat-6a, Cat-7, and Cat-8 are always shielded. But if you do not have the need for these and you are satisfied with Cat-5e for example you can choose.

Shielded cables are a little more expensive but they will provide you with a coating that will eliminate interference from outside waves making cables more reliable. Of course, if the cable will go through a room that does not have many radio waves or some other interferences then buying a shielded cable is a waste of money.

Cable platings

Usually, there are two types of connector platings on connectors, silver, and gold, and people usually think that gold is much better but there are major differences between silver and gold platings and truth to be told there is no better one, both are different and should be considered depending on your need.

Silver plating will provide you with faster speed since its conductivity is larger than gold, but gold is slower on the oxidation front so its life span is longer. On the other hand, if your cables are always connecting and disconnecting gold will be first to be scrubbed off from the surface since the gold coating is much thinner.

Overall if you would only connect cable once and have slower internet than cable capacity gold is the way to go, in another case if you would use the cable as always connecting and switching and your internet plan is the same as cable transfer capacity you might want to go with silver one.

Cable material quality

Network cables are made from copper, your standard conduction material but even here there are differences in quality and therefore the chance of pocket losses over it. More quality less loss and more stable connection and this will depend on the purity of copper that is used in the cable itself. More purity in copper, more stability, simple as that.

Conclusion

So as you can see, there are a lot of different things that will influence your pick of proper network cable but the overall best advice is to get one that will fit well into your needs and setup. pair it up with your router and your internet plan since just simply buying something that you can not use is really a waste of money.

If, while using your computer, you encounter the ACPI.sys Blue Screen error, read on as this post will guide you in fixing the problem. The ACPI.sys file is a Windows operating system file that is related to the MSDN 2939. ACPI.sys, the Windows ACPI driver, is an inbox component of the Windows operating system. It is the one that supports the power management as well as the Plug and Play or PnP device enumeration. And so if this file ends up getting corrupted, it is known to cause a Blue Screen error. Another possible cause for the ACPI.sys Blue Screen error includes RAM issues, incompatible firmware, hard disk issues, corrupted drivers or malware infection, and so on. Here are some Blue Screen errors that can be triggered by the ACPI.sys file:

• KMODE EXCEPTION NOT HANDLED
• PAGE FAULT IN A NONPAGED AREA
• SYSTEM THREAD EXCEPTION NOT HANDLED
• IRQL NOT LESS OR EQUAL
• KERNEL DATA INPAGE
• SYSTEM SERVICE EXCEPTION

To fix the Blue Screen error associated with the ACPI.sys file, refer to the instructions provided below.

Option 1 – Try to recreate the ACPI.sys file

If the first option didn’t work, the next thing you can do is to recreate the ACPI.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. This is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
• From there, look for the file named ACPI.sys and rename it to ACPI.old.

Note: As you can see, the file’s extension has changed from .sys to .old.

• Now restart your computer and check if the ACPI.sys Blue Screen error is now fixed.

Option 2 – Try to update or rollback the ACPI Driver

The first thing you can try to fix the Storport.sys Blue Screen error is to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Tap the Win + X keys to open the Win X menu and from there, select the Device Manager.
• After opening the Device Manager, look for the ACPI.sys driver and right-click on it, and then select Properties.
• Next, go to the Driver section. Note that the rollback option would only be available if you’ve recently updated the ACPI.sys driver. So if you can’t see it then click on the Update Driver button.
• After that, Windows will automatically check for the problems that could be related to the Blue Screen error.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver. On the other hand, if updating the ACPI driver, didn’t work, you can also try to copy the ACPI.sys system driver file from the System32 folder of another computer that’s functioning properly and runs the same Windows OS version. Afterward, place it on your problematic computer and check if it fixes the BSOD error or not.

Option 3 – Run System File Checker or SFC scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

 Reboot your PC.

Option 4 – Run the Blue Screen Troubleshooter

Troubleshooting Blue Screen of Death errors wouldn’t be complete without the Blue Screen troubleshooter. As you know, it is a built-in tool in Windows 10 that helps users in fixing BSOD errors like ACPI.sys. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 5 – Run System Restore

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Check-in your setting to see if there are some uninstalled or pending updates waiting to be installed and if that is the case install them all. After completely updating your Operating system error should vanish and you should be able to install Microsoft office without issues.

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.

HDMI which stands for High Definition Multimedia Interface is an audio/video interface that can be used to interconnect various multimedia devices. One of the common use for HDMI is when a CPU is connected to a monitor and a projector. Aside from that, it can also be used in connecting Blu-ray players and laptops to televisions as well as monitors. One of the main advantages of using HDMI is that it can transmit both audio and video at high qualities such as 4K using only a single connection. However, you may also experience some issues in using it every now and then and one of them is when you find that after connecting the devices using the HDMI port, the screen appears to be black and there is no audio output. In such cases, there are a variety of hardware malfunctions that could be causing the problem with the HDMI connectivity. Although there a lot of potential causes, there are also potential fixes you can try to fix the problem. Before you troubleshoot the HDMI Port problem, you might want to perform System Restore first as it might help you in fixing the problem. It could be that you’ve made some changes in some of the settings in your computer that triggered the problem. Thus, you can try run System Restore to undo them, refer to these steps:

• First, press the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the Stop error is fixed or not.

If the problem still persists after System Restore, then follow the given options below to further troubleshoot the problem.

Option 1 – Try to physically check the hardware of your computer

The first thing you can do is to check the physical status of the hardware in your computer. You can clean the dust off the hardware components like the Network Card or Graphics Card of the computer.

• You can try to plug out the HDMI cord/cable from both source and destination and then plug it back in after a couple of minutes.
• You can also check if the HDMI cable you are using is still in working condition.
• You can also try to change the source and the destination of the video and see if either one of them is in a non-workable state.
• Try checking if your settings are how they should be as intended in the “Project my screen” option by tapping the Win + P key combination on your keyboard.

As you know, NVIDIA is one of the topmost graphics cards used and it has been that way for several years already. And in those years, the company has managed to release the best cards on the market. However, there are still times when some things fail and don’t work as expected due to some NVIDIA driver issues. As of late, one of the issues users reported about NVIDIA drivers is that it keeps on crashing on a daily basis. It gets to the point where they aren’t able to play games anymore while some users experience lag and rendering issues. In addition, some users also reported that their computer display tends to freeze sometimes, and then things would seem to go back to normal but only for a short span of time as the crash seems to happen every 10 minutes. This can be extremely annoying as you won’t be able to use your computer properly. If you are one of these users, worry not for there are several ways you can try to resolve the problem in your Windows 10 computer. Make sure to carefully follow the options given below.

Option 1 – Try checking if the NVIDIA graphics card is enabled

Although the problem is quite massive, the fix could be as simple as enabling the NVIDIA graphics card if it turns out to be disabled. There might be some strange reason why your graphics card disables itself. Thus, the best and first option you can try is to check if the NVIDIA graphics card is enabled or not. To do so, follow these steps:
