If you have a firewall installed on your system, you may come across the error code 0x6d9. This error occurs when opening Windows Firewall with advanced security. The error code 0x9d9 is displayed as:
“There was an error opening the Windows Firewall with Advanced Security snap-in.
The Windows Firewall with Advanced Security snap-in failed to load. Restart the Windows Firewall service on the computer you are managing. Error code: 0x6D9”
This occurs when the Windows Firewall service is missing. The service doesn’t start due to permission errors on various registry keys. It is a critical blue screen of death error code that turns the computer screen blue and causes the Windows to shut down.
If this error code is not fixed it may start appearing more and more frequently resulting in total system corruption.
Error CausesVirtually, the underlying cause for Windows Firewall error code 0x6d9 is a damaged registry. The registry is the database of the system that saves all the activities including web browsing and programs installed and uninstalled and junk files on the PC.
The registry saves all the information in the RAM, your hard disk. As the disk gets filled with files, it then requires more power to run which impacts the performance of the PC and slows it down.
Simultaneously, since the hard disk is overloaded with data, it exposes the registry to file damages, fragmentation, and corruption which then eventually causes hindrance in running calling programs and running them on your system because files are either corrupt or missing.
Other than cluttered disk issues, registry errors also occur due to viral and malware attacks. If the Firewall is inaccessible, your system is prone to malware.

You probably heard about switches for LAN but not a lot of people heard about KVM switches. So what exactly is KVM switch?

If we look at the name, it is a shortcut for Keyboard, Video & Mouse and the original idea was to have multiple computers but one keyboard, mouse, and monitor. These peripherals would be connected to the KVM switch and other computers could all use one set of these on the fly when needed.
The technology behind the switch is a little interesting since it will actively fake signals to other computers that are not using peripherals. Once they are switched to them the transition is smooth and not noticeable. In old days these switches were more important than today since on every mouse or keyboard disconnection you had to reboot the computer, and although today that is not the case CPU will still detect disconnection and on the next connection it will run through the ID of the device and try to use the existing driver and if peripheral was connected in other USB port, it will install the same driver but connect it to the new USB port.
This type of reconnection can slow down work and place unnecessary load on the CPU so that is why KVM will fake connection in order to make switching externals on the computer smooth and in nick of a time.
These days modern KVM switches will offer you more options than just being able to switch between keyboard, mouse, and monitor. Modern switches now offer Lan, audio, and many more various options.
There are also different kinds of switches offering you only one option, like for example just a Video switch that will let you use one monitor on three computers and many more other specialized options.
So far we talked about Hardware switches, a real device being able to take peripherals into it and switch computers on the fly. On the other line, we have software switch solutions that will have specific software installed on all computers and have it run at all times, and switching between them will be through specific software.
There are two very good and main advantages of using software solutions instead of a hardware one. First, of course, is the price, since the most popular Synergy is an open-source solution, completely free of charge. The second big advantage is that software switch is not limited to how many computers can you use. Hardware switches tend to go to a large number like 16 but if you have a large cluster of computers over a LAN, let's say 30 then the box solution might be difficult.
On the other hand software solution will switch only keyboard and mouse since each other computer will have to have some screen on it in order to work. Both solutions have their strong advantages and disadvantages and it is up to you to choose one that best suits you.
If you are multitasking with a lot of computers or just need your peripherals from time to time to connect to another machine then the KVM switch is something that you might find the use of. Just be aware that if you go for some cheap switch you might experience some lag on your peripherals, but if that is not a concern you can get hardware one for as low as $50 USD.
