A required device isn’t connected

The File Explorer in Windows 10 provides several ways to organize the contents of folders and files in the system. Windows users can utilize some efficient styles to view the contents of the file system as per the user’s requirement. A user may opt to display the file picture in large size thumbnails while the other one could opt to set the icons of folder and files in a small or medium size list. On the other hand, while setting up several styles for the folder and file icons, some Windows 10 users have experienced some unusual issues where there is the Black background showing up behind folder icons. They tried refreshing the File Explorer a couple of times but it didn’t help in fixing the problem and the black squares are still visible on some folder icons. The black squares behind the folder icons might look disturbing though it’s not really a big problem and is merely a graphical glitch that does not cause any damage or whatsoever to the content of the folder and files. The most likely cause of this glitch might have something to do with the corrupted system files or it could also be caused by outdated thumbnail caches. In addition, graphical glitches like this one could also occur if you are using out outdated graphics drivers. To fix this problem, you need to follow the options laid out below.

Option 1 – Try using the Disk Cleanup to remove Thumbnail files

The Disk Cleanup tool is one of the options you can try to fix the black squares behind the folder icons. Through this tool, you can delete all the Thumbnail files on your disk. To use it, refer to these steps:

• Open the Search bar and type “disk cleanup” in the field.
• After opening Disk Cleanup from the search results, then from the drop-down menu select the C: drive to clean up and click OK.
• Wait for the scanning process to complete. Once it’s done, select the files you want to delete.
• Ensure that you select the box labeled “Thumbnails” under the Files to Delete section then click on OK.
• After that, a confirmation box will appear, just click on Delete files to delete the files permanently.
• Restart your PC.

Option 2 – Try resetting the Thumbnail cache

You have the option to manually delete the Thumbnail Cache to resolve the black square background behind the folder icons issue. Follow the steps given below to reset the Thumbnail cache.

• Open the File Explorer.
• Next, navigate to the View tab and select the option with Hidden items to display all the hidden folders and files.
• Next, go to this path: C:Users<username>AppDataLocal
• In the given path, make sure that you put your actual username in the username field. Then look for a file named “IconCache.db”. Right-click on this file and click on Delete.
• After that, go to this path: C:Users<username>AppDataLocalMicrosoftWindowsExplorer
• From there, select all the files and delete them.

Note: If a prompt appears saying, “The files are in use and cannot be deleted”, simply select the “Do this for all current items” option and then click on Try Again. If you get an error message, click on Cancel to close the window and restart your computer.

Option 3 – Try updating or reinstalling the Graphics driver

• Tap the Win + R keys to open the Run dialog box and then type in devmgmt.msc and tap Enter or click OK to open the Device Manager.
• Expand the section for the outdated device drivers.
• And then select the outdated driver(s) and right-click on it/them.
• From the drop-down menu, select the Update Driver option if you wish to update the driver or select the Uninstall device if you want to uninstall the driver and then follow the on-screen instructions to install the latest version of the driver.
• Restart your PC after the installation to allow the system to reinstall the driver.

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 everyone and welcome to another great tutorial from errortools.com I hope everyone is feeling great and that you are prepared to boost the performance of your computer. This time we will speed up Windows startup time and overall performance by eliminating startup programs that we don't need and do not use. Microsoft itself and some application developers tend to have some applications or some services always active and set to be loaded on Windows startup. If you want to change which of these applications are starting up with your Windows and change them, follow this easy guide and you will be speeding up your Windows in no time. First thing is to open a task manager, fastest and most direct way of doing this is with a keyboard combination of CTRL + SHIFT + ESC When Task Manager opens, click on the startup tab on top. Once you click on startup you will get a list of applications that are set to be started when Windows is booted. You can now click on the application and then click on disable on the bottom button, the application status will update in task manager to disabled and it will not be booted anymore when Windows starts. In this same manner, you can enable back some applications if you changed your mind about them. Please note that some applications are using some services and must have them running or they will not work properly. The best practice is to disable applications you are positive you will not use or use rarely so you do not want them to slow down Windows.

Even with the new Groove Music in Windows 10, a lot of users still prefer to use the old Windows Media Player. This isn’t surprising since Windows Media Player still remains to be one of the best players you can find. However, that does not mean that it is without flaws as it could still encounter some issues from time to time. One of the issues you might encounter when using the Windows Media Player is when you try to burn DVDs or CDs but end up failing due to an error that pops up that says, Windows Media Player cannot detect the length of the file. At the time of writing, it isn’t clear yet what the real cause of the error is. However, there are several fixes that are provided in this post for you to check out so you can resolve the problem. You can try to get rid of any unsupported files from the burning list or you could also try running the Windows Media Player troubleshooters. Aside from that, you could also try to drag and drop music or change the burning speed. For more details, refer to the following options.

Option 1 – Get rid of the unsupported files from the burning list

You must get rid of the unsupported files from the list of files to burn. This list can be found on the right-hand side of the Windows Media Player. One of the indications that a file is causing problems is when there is a white cross in a red circle next to the file. You can simply click on that icon to remove the file from the burning list. Once you’ve gotten rid of all the unsupported files, try to burn your files to the CD or disk once more.

Option 2 – Try running the Windows Media Player troubleshooters

The next thing you can do to fix the error is to run the built-in troubleshooters for the Windows Media Player. Windows 10 actually comes pre-packed with three troubleshooters designed for Windows Media Player. They can help in fixing the “Windows Media Player cannot detect the length of the file” error. To run these troubleshooters, simply tap the Win + R keys to open the Run dialog box and type “msdt.exe -id WindowsMediaPlayerConfigurationDiagnostic” for the Windows Media Player Settings troubleshooter or type “msdt.exe -id WindowsMediaPlayerLibraryDiagnostic” for the Windows Media Player Library troubleshooter, or type “msdt.exe -id WindowsMediaPlayerDVDDiagnostic” for the Windows Media Player DVD troubleshooter.

Option 3 – Try to drag and drop music

Another thing you can check out is to drag and drop all the tracks into the Windows Media Player before you burn them. All you have to do is open the folder where the tracks are located and highlight all of them and then drag them to the Windows Media Player. It should now be able to detect the length of each one of the tracks without any errors.

Option 4 – Try to change the burning speed

Since the burning speed is set to fastest by default, you can try to change the burning speed to resolve the problem. Just open the Options window and then go to the Burn tab. From there, select either Medium or Slow burning speed and save the changes made. Now try to burn your files to the CD or disk once again.

There are several kinds of errors you could encounter when you are running Windows 10 on a virtual machine. The Windows OS knows the difference between booting up in a standalone computer or in a virtual machine. This is why some specific drivers and system capabilities are used while emulating the Windows OS on software and during this phase, there are times when the System Preparation may throw up an error that says, “A fatal error occurred while trying to sysprep the machine”. This kind of error arises due to a race condition wherein the Sysprep command tries to stop the Microsoft Distributed Transaction Coordinator or MSDTC service and the VMware tool tries to start the MSDTC service. You may also see the following messages logged in the Setuperr.log file:

• [0x0f0082] SYSPRP LaunchDll:Failure occurred while executing ‘C:Windowssystem32msdtcprx.dll,SysPrepDtcCleanup’, returned error code -2146434815[gle=0x000000b7]
• [0x0f0070] SYSPRP RunExternalDlls:An error occurred while running registry sysprep DLLs, halting sysprep execution. dwRet = -2146434815[gle=0x000000b7]
• [0x0f00a8] SYSPRP WinMain:Hit failure while processing sysprep cleanup providers; hr = 0x80100101[gle=0x000000b7]

To fix the 0x0f0082, 0x0f0070, 0x0f00a8 Sysprep errors, you can check out two potential fixes. First, you have to check the status of the MSDTC service and the second one is to check the settings in the Windows Registry. Note that these fixes are proven to be effective on many users and apply to several versions of Windows, including Windows 10.

Option 1 – Check the status of the MSDTC service via Command Prompt

As mentioned, the error could be caused by the malfunctioning of the MSDTC service or it. Thus, you have to uninstall and reinstall the MSDTC service to resolve the problem and you can do that using Command Prompt. Follow the steps below.

• In the Start Search, type “command prompt” and from the results, right-click on Command Prompt and then select the “Run as administrator” option to open it with admin privileges.
• If a User Account Control or UAC prompt appears, just click on Yes to proceed.
• Once you’ve opened Command Prompt, execute this command: msdtc –uninstall
• The command you just entered will uninstall the MSDTC service. After that, you need to execute this second command to reinstall the service: msdtc –install
• Now exit Command Prompt and check if the error is now fixed.

Option 2 – Check the Registry settings

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and click OK or hit Enter to open the Registry Editor.
• After opening the Registry Editor, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSoftwareProtectionPlatform
• From there, look for a DWORD value that’s named “SkipRearm” and double click on it.
• Then change its value data to “1”.
• Restart your computer to apply successfully apply the changes made and check if it was able to fix the error.

Recently, a number of Windows 10 users reported an issue wherein they try to print from their PCs but were unable to and got an error message instead that states, “Port in use, please wait”. However, no matter how long they waited, nothing changed and they were still unable to print from their computers. On the other hand, when some of the users attempted to print wirelessly from their mobile devices, the printing continues which indicates that there is some issue between the computer and the printer. So if you are one of the users who are currently facing this problem, then this post should help. To fix this issue with your Printer, here are some possible fixes you can try that might work.

Option 1 – Run the Printer Troubleshooter

The first thing you can do to fix the “Port in use, please wait” error is to run the Printer Troubleshooter. This built-in troubleshooter in Windows 10 can help you fix most print issues. It checks if you have the latest printer drivers and then tries to fix and update them automatically. Aside from that, it also checks if you have connectivity issues or if the Print Spooler and the required Services are running fine. To run it, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msdt.exe /id PrinterDiagnostic” in the field and click OK or hit Enter to open the Printer Troubleshooter.
• Then click the Next button and follow the next on-screen instructions to fix the issue with the printer.

Option 2 – Try updating the Printer drivers

You might also want to try updating your printer drivers. All you have to do is locate the USB Composite Device. For complete details, follow the steps below.

• 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 USB Composite Device option and right-click on it, and select the Update Driver from the options.
• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: You also have the option to download the latest version of your Printer from the manufacturer’s website.

Option 3 – Try selecting the correct port for your Printer

If the first two options given above didn’t work, then maybe it’s time to select a correct port for your printer since the wrong port has been selected which is why you’re getting the “Port in use, please wait” error.

• Open “Devices and Printers” from the Start search.
• Next, look for your printer from the list of devices and right-click on it, and then select Printer Properties.
• Now go to the Ports tab under the newly opened Properties window and make sure that the port type matches the connection on the list of ports currently in use.

Note: If your printer is using a USB connection then the port should have a USB or DOT 4 in its description but if your printer is using a network connection then it should have the following description:

• WSD
• Network
• IP

And if you notice that there are several listings for the same type of port, you have to change the selection to a different one and then click the OK button to save the changes made.

Hello and welcome everyone, just a few years ago we had FLASH video content on the internet, we had FLASH games, full FLASH website experiences, and more, but then flash was shut down mostly due to security reasons meaning that in just a few months we have lost most of FLASH web content. However, there is still FLASH content on the internet even today, there are still FLASH videos and flash games, but we can not play any of that content since browsers do not support FLASH and you can not get the FLASH plugin for browsers. So what might be the solution for this situation?

Ruffle and FLASH emulation

Emulation of course. We will not be able to get the flash player working, well at least not the original and official one, but we can make flash content playable again inside our browsers. The first thing is first, we need to get an emulator package from the internet in order for this trick to work, one we will be using is RUFFLE. It is lightweight, it is free, it is open source and it is reliable, everything we need. Download RUFFLE from its official website here. For Chrome and Edge download the ZIP package, for Firefox, go to the Firefox section of the tutorial. There is also a desktop version of RUFFLE there so if you are keen on playing your flash content on your desktop computer you might well grab that as well, but for the sake of this tutorial where we are enabling flash in our browsers, we will not focus on that part since it is pretty straightforward. Now once you have downloaded the RUFFLE emulator, please extract it to the desired folder somewhere on your computer. Once it is extracted, start your browser of choice and follow instructions.

FOR CHROME:

1. Navigate to: chrome://extensions/
2. Turn ON developer mode in the top right corner
3. Click on Load unpacked
4. Navigate to the folder where you have extracted RUFFLE

FOR EDGE:

1. Navigate to: edge://extensions/
2. Turn ON developer mode on the bottom left corner
3. Navigate to the folder where you have extracted RUFFLE
4. Turn RUFFLE ON

FOR FIREFOX:

1. Go to the RUFFLE download page, we can not use the zip package we were using for Chrome and Edge
2. Right-click on the Firefox download link
3. Save link by clicking on Save link as...
4. Navigate to about: debugging
5. Click on this Firefox
6. Click Load Temporary Add-on
7. Select the .xpi that you have downloaded

BONUS:

If you want to enable FLASH content live on your website use:  <script src="path_to_ruffle/ruffle.js"></script>

When trying to run Computer Management, or when running mmc.exe or compmgmt.msc from a command prompt you get the error that the application has been blocked for your protection then keep reading in order to solve the issue. This is a permission issue where if a regular user tries to run such system tools will result in saying that it has been blocked. Along with this, you may have a Group Policy issue. This can be fixed, but you will need admin permission to achieve it. It’s because when they are run from the command prompt with elevated privileges, it works.

1. Change Group Policy Settings

   If your account is an admin account, and you are still facing the issue, then change the group policy settings: Open Group Policy Settings by typing gpedit.msc in the run prompt followed by pressing ENTER Navigate to User Configuration > Administrative Templates > Windows Components > Microsoft Management Console > Restricted/Permitted snap-ins Locate Computer Management policy, and double click to open it Enable it, exit Group Policy. When Enabled: The snap-in is permitted and can be added into the Microsoft Management Console or run from the command line as a standalone console. When Disabled: The snap-in is prohibited and cannot be added into the Microsoft Management Console or run from the command line as a standalone console. An error message is displayed stating that the policy is prohibiting the use of this snap-in.

2. Temporarily disable UAC

   UAC is the user access control panel, and if you need to run the command right away, you can choose to disable it for some time. Click on the Start button, and then type UAC to find the User Account Control Settings. Click to open, and then slide down the notification setting at the bottom. It will temporarily allow launching the application as there is no check. However, make sure to switch to default once you are done.
