In case you don’t know, the .Net Framework is a programming infrastructure introduced by Microsoft. You will need it to run on lots of services and applications. Note that most of the applications that require the .Net Framework are packed with their installation files which is why it will be installed automatically on your computer when you install an application. However, there are instances when you’ll get an error message saying, “The .NET Framework 4.7 is not supported on this operating system” while trying to install the .NET Framework as a standalone service. The very reason why this error message appears is stated in the error message itself. Although the .Net Framework is supported on Windows 10, it is not actually compatible with some other Windows 10 versions. So it is most likely that you are seeing this error message because the .Net Framework in your computer is not compatible with the Windows 10 version you are running. Since that’s the case, you need to update Windows 10 to fix the problem. Updating your Windows 10 computer is the only solution you can try to fix this problem. Thus, it is advised that you check for Windows Updates even if you are now using the latest version of Windows 10. And since the issue is caused by an incompatible operating system version, once you install the exact version of Windows 10 required by the .Net Framework, the problem will be fixed. Simply follow the steps given below to do so.

• Step 1: Tap the Win + R keys to open the Run dialog box.
• Step 2: After that, type in “winver” in the field and tap Enter.
• Step 3: Next, your Windows 10 version should be given in the new window that appears. Take note that the number after the Version which is in the second line is your version number of Windows 10. And that the number must be 1507 or 1709. The first two digits in these numbers are the year while the second two represent the month when the update was released. So if you are running a 1709 version, this means that the Windows 10 version you are using was released in September 2017.
• Step 4: The next thing you have to do is to make sure that you have the Windows 10 version that’s compatible with the .Net Framework. To verify, you need to click here and click on the System Requirements.

After opening the link, take a look at the Supported Operating System section where it says, “Windows 10 Anniversary Update” and “Windows 10 Creators Update”. Since there are users who are not familiar with the version numbers related to both the Anniversary and Creators updates, refer to the list given below.

• November Update (1511)
• Anniversary Update (14393)
• Creators Update (1703)
• Fall Creators Update (1709)
• Spring Creators Update (1803)

As you can see, the Creators Update has version 1703 while the Anniversary Update has version number 14393 so if you are using a version lower than the 14393 version then it’s no wonder you aren’t able to install the .Net Framework 4.7 on your Windows 10 PC. Now all that’s left to do is to update your Windows 10 version and make sure that you will be updating it to the latest version available and then try installing the .Net Framework again.

Usually when online service is not working or when something goes wrong online it is DNS, well that is what most of the time is the case. And yes, DNS or Domain Name Server seems to be an issue with Facebook being completely down along with Instagram and wassap. The true cause is that there is no working Border Gateway Protocol (BGP) routes into Facebook's sites. BGP is the standardized exterior gateway protocol used to exchange routing and reachability information between the internet top-level autonomous systems (AS). Most people, indeed most network administrators, never need to deal with BGP. Cloudflare VP Dane Knecht was the first to report the underlying BGP problem. This meant, as Kevin Beaumont, former Microsoft's Head of Security Operations Centre, tweeted, "By not having BGP announcements for your DNS name servers, DNS falls apart = nobody can find you on the internet. Same with WhatsApp btw. Facebook has basically de-platformed themselves from their own platform." Many people are very annoyed by this and with the fact that they cannot use their social media platforms but it seems that Facebook employees are in even bigger annoyance as it was reported that Facebook employees can't enter their buildings because their "smart" badges and doors were also disabled by this network failure. If true, Facebook's people literally can't enter the building to fix things. Reddit user u/ramenporn, who claimed to be a Facebook employee working on bringing the social network back from the dead, reported, before he deleted his account and his messages: "DNS for FB services has been affected and this is likely a symptom of the actual issue, and that's that BGP peering with Facebook peering routers has gone down, very likely due to a configuration change that went into effect shortly before the outages happened (started roughly 1540 UTC). There are people now trying to gain access to the peering routers to implement fixes, but the people with physical access is separate from the people with knowledge of how to actually authenticate to the systems and people who know what to actually do, so there is now a logistical challenge with getting all that knowledge unified. Part of this is also due to lower staffing in data centers due to pandemic measures." Ramenporn also stated that it wasn't an attack, but a mistaken configuration change made via a web interface. Both BGP and DNS are down, the "connection to the outside world is down, remote access to those tools don't exist anymore, so the emergency procedure is to gain physical access to the peering routers and do all the configuration locally." Technicians on site don't know how to do that and senior network administrators aren't on site. It seems that it will all be down for a couple of more hours before the issue is resolved.

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.

Modern KVM switch

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.

Software switches

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.

Conclusion

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.

Hello and welcome to errortools another tutorial which aims to make your computer life easier and more relaxed. This time we will be talking about how to switch sound output devices in Windows 10 in a matter of seconds between Headphones and external speakers, Between 2 different speakers, or any other audio output device in general. Windows 10 with its updates has really gone from OK to one of the greats, little hacks and shortcuts which every update has introduced have really made life easier.

Option 2 – Run System File Checker scan

If restarting the explorer.exe process didn’t work, you can also try running the System File Checker or SFC scan to fix the error. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in this command: sfc /SCANFILE=c:windowsexplorer.exe

Note: If you are using a 64-bit Windows operating system, enter the “sfc /SCANFILE=C:WindowsSysWow64explorer.exe” command instead.

• Wait until the process is completed and then restart your computer.

Option 3 – Run the DISM tool

You might also want to run the DISM tool. This tool is known to repair potentially corrupted files in your system as having them could also system issues like the “System call failed” error. To repair these corrupted system files, you can run the DISM commands:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.

Graphic cards are essential to our computers but from time to time in the race to make better GPU and to grab a large portion of the market bad drivers get released and can create really unwanted and unpleasant experiences, from Windows freezes to the black screen of death, to AMD driver Windows crashing down and many more. This article will cover basic troubleshooting with AMD drivers and offer you solutions on how to fix them.

1. Rollback the previous version of the driver.

   Installing the new driver version is the reason for this particular error, so naturally rolling back the previous version which was stable and did not cause issues will solve the problem. To roll back the previous version of drivers follow the next steps: Open Start menu and click on settings, go to system and choose Apps and features Find: AMD Catalyst Install Manager, right-click on it, and choose to uninstall Go to AMD official website and download the previous driver version, install it on your computer Turn off automatic driver updates and reboot your system

2. Reinstall the driver

   Sometimes it is not a bug in the released driver, it is a corruption of files because of file transfer or any other specific reason. The reinstalling driver will fix an issue if this is the case. To reinstall the driver Press ⊞ WINDOWS + X and choose Device Manager Expand Display adapters, right-click on AMD device and choose to uninstall Go to the official AMD website, download the latest driver and install it Reboot your system

3. Disable browser extensions

   Some users have reported that error occurs only when they are watching videos online, if this is your case, go to your browser options and disable extensions to see if this will remove the problem.

5. Clean your graphic card

   Sometimes this error can happen due to excessive dust on your GPU, if you have the expertise, clean it or take it somewhere to be cleaned.

External hard drives have become essentials as they store data. However, they are also prone to issues and one of them is the “The device is not ready”. You could encounter this error when you try to access your connected hard drive. This error won’t allow you to access the contents of your hard drive so unless you fix it, you won’t be able to access any of the files on your hard drive. One of the most likely causes of this error is a hardware defect. Aside from that, it could also be due to loose connections, obsolete device drivers, as well as compatibility issues between the operating system and the hard drive. Before you start troubleshooting the problem, you need to determine if you were able to access your hard drive before you encountered the error or not. If not, you need to check the compatibility of the device with your operating system as it could be the reason why you’re getting the error. There are several potential fixes you can check out to fix this error. You can try to check the hardware connections, run the built-in Hardware and Devices troubleshooter, as well as the USB troubleshooter. You could also run the CHKDSK utility or update the drivers of the device or the USB drivers.

Option 1 – Try checking the hardware connections

The first thing you have to do before you further troubleshoot the problem is to check the hardware connections of your computer and see if there are damaged ones, just like with USB ports, it would also affect the overall connectivity of the device with the computer. So if you notice some irregularities in the connecting cable physically, you might have to buy another one and replace it and then see if it fixes the problem or not.

Option 2 – Run the Hardware and Devices Troubleshooters

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Note: You could also try to run the USB troubleshooter as it could also resolve the problem.

Option 3 – Run the CHKDSK utility

As you know, the CHKDSK utility can help you in identifying the bad sectors in a drive and fix them automatically. Thus, you can run it to fix the “The device is not ready” error when you connect your USB drive to your computer.

• Open Command Prompt with admin privileges.
• Next, type and enter this command to execute it: chkdsk /f <drive>
• Now, wait until the process is completed and exit Command Prompt.
• Restart your computer and try connecting the USB drive again and see if the error is fixed.

Option 4 – Try to update the drivers of the device

Although you can always update the device drivers using the Device Manager, you might want to try downloading the latest set of drivers directly from the manufacturer’s website. Once you’ve downloaded them, install them right away and then correct the external hard drive.

Option 5 – Update or reinstall the Universal Serial Bus Controller driver

If updating the drivers of the device did not fix the “The device is not ready” error, you can try to update or reinstall the Universal Serial Bus Controller drivers instead of using the Device Manager. Refer to the following steps:

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right-click on each one of the USB drivers and select the Update Driver from the menu.
