There are times when after you upgrade your Windows operating system, the System Logs under the Event Viewer will display an error message saying, “Event ID 10010 error – The server did not register with DCOM within the required timeout”. What is DCOM? DCOM stands for “Distributed Component Object Model”. It is a proprietary Microsoft technology that allows the Component Object Model or COM software to communicate across a network. You can consider it as an extension of COM which is equipped with the capability of solving a couple of inherent problems related to the COM model to the better use over a network. COM is a tool that’s used for advanced configuration and troubleshooting in Windows 10. Developers usually use it to configure routine components and application behavior like participation in transactions and object pooling and so on. The Component Services needs the DCOM wire protocol in order to communicate with the Component Object Model components on other computers. By default, in a Windows-based system, the network computers are configured initially to enable DCOM. There are also some components in Windows that might require registering themselves with DCOM. However, if they fail to do so, you will encounter the “The server did not register with DCOM within the required timeout” error. To fix this, here are some suggestions you can check out.

Option 1 – Try to use the Component Services

• Tap the Win + R keys to open the Run dialog box.
• Then type “dcomcnfg” in the field and tap Enter to pull up Component Services.
• Next, double click on the Computers folder located in the right pane and right-click on My Computer, and select the Properties option.
• After that, switch to the COM Security tab under My Computer Properties and then go to the Access Permissions section.
• From there, click the Edit Default button and in the new window that appears, apply the correct permission to objects under the Group or user names section.
• Once you’re done, click OK and exit. This should fix the error.

Option 2 – Make sure that Function Discovery Resource Publication Properties Services is running

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “services.msc” in the field and hit Enter to open the Services Manager.
• Next, scroll down and look for the “Function Discovery Resource Publication” entry and double click on it.
• Then switch to the General tab and from there, make sure that the Startup Type is set to “Manual (Triggered).
• You also have to make sure that the service is running so if it’s not, just click on the Start button to start the service.
• Now click on Apply to save the changes made.

Option 3 – Try resetting the default DCOM permissions

• Tap the Win + R keys to open the Run dialog box.
• Then type “dcomcnfg” in the field and tap Enter to pull up Component Services.
• After that, expand Component Services > Computers and right-click on My Computer, and then select Properties.
• Next, go to the Default Properties tab, and in the Default Distributed COM Communication Properties section, make sure that:
  • Default Authentication Level is set to Connect
  • Default Impersonation Level is set to Identify.

SMB which stands for “Server Message Block”, is a protocol used for file sharing. It provides the Read and Writes operating on network devices. Thus, it is why it is widely used when accessing a server-based in Linux. Its latest version is the SMB2 which follows after SMB1. The SMB2 contains more fixes to vulnerabilities that were found in SMB1. The predecessor was vulnerable since it served as a gateway to various modern ransomware which is why Microsoft disabled it by default starting with Windows 10 v1709. When you try to share a file, you will get the following error message:

“Microsoft Windows Network: You can’t connect to the file share because it is not secure. This share requires the obsolete SMB1 protocol, which is unsafe and could expose your system to attack. Your system requires SMB2 or higher.”

In this post, you will be guided on how to check if the SMB2.0 version can be installed on your Windows 10 computer. To get started, follow the steps below. Step 1: Tap the Win + X keys to open the Device Manager. Step 2: After that, click on the Windows PowerShell (Admin) option. Step 3: In the Windows PowerShell window, type the following command and hit Enter:

Get-SmbServerConfiguration | Select EnableSMB2Protocol

Note: After entering the command, you will see the following content on your screen which means that your Windows 10 computer is now capable of running the SMB2 protocol Now all that’s left for you to do is to enable the SMB 2 protocol on your Windows computer by enabling the SMB 1 protocol first and then upgrading it to SMB 2 afterward. Refer to the steps below for more details. Step 1: Tap the Win + I keys to open the Settings app. Step 2: Then type in “control panel” in the search area and click on Control Panel from the search results. Step 3: After opening Control Panel, click on Programs. From there, select the “Turn Windows features on or off” option under the larger menu of Programs and Features. Step 4: After that, Windows Features will appear on your screen. And from there, make sure that you select SMB 1.0/CIFS File Sharing Support and then click on OK. Step 5: Now let it install all the required files and then restart your computer to apply the changes made successfully. After your computer has restarted, the SMB 2 protocol should now be supported on your Windows 10 computer. Note: On the other hand, you can also enter the following command in the Windows PowerShell window. Just make sure you have admin rights to enable it.

Set-SmbServerConfiguration –EnableSMB2Protocol $true

Hello everyone, in today's tips and tricks we will focus on providing you with various solutions on how to solve the Device not migrated error that appears after the Windows update has been performed. Sometimes sadly updates to our operating systems can introduce us to various issues that look scary but in reality, they are solvable and not so scary at all. After all who would not find this message concerning, especially when it happens in the middle of work. The first thing that would pop into my mind is that I have lost tons of work and that something in my hardware has gone very wrong and it is dead. Luckily that is not the case and this error means that due to Windows update drivers were not properly transferred due to some compatibility issues, maybe it was a corrupt update file, etc. Of course, the reason could be hardware malfunction as well, but if everything was working fine before the update, it is a software issue, and I must say it is a common one and fixable. Please keep reading this guide in order to fix the Device not migrated error.

1. Update the Driver

   You should always try this first, if the device is not recognizable, try updating its driver and see if the problem vanishes. In order to update the driver, we will need first to locate which device has not been migrated properly, we will do this with help of a search engine on the internet like google for example. So open your browser of choice, go to a search engine (google for example) and type in the search box first line from your error message, yes, that scary one. You will be given which device has malfunctioned and was not migrated properly, now we will locate the device and update its drivers. To do this press WINDOWS + X on your keyboard to bring up Windows secret menu and choose device manager. Find device inside device manager, right-click on it, and choose properties. Go to the events tab and make sure that the device has migration issues. You have now 3 options for updating the driver, you can do it manually, automatically, or with the driver installer. We will cover all 3 options so you choose which one best suits you. OPTION 1: Manually. Close the Properties tab, go to the device manufacturer website and download the latest driver, if there are no drivers there, the only executable installer for the device skip this step and try the other 2. After you have downloaded the driver package from the website, right-click on the device and choose update driver. Now navigate to the folder where you have downloaded your driver package and update the driver. Reboot your system. OPTION 2: Automatic update. Close the Properties tab, right-click on the device and choose to uninstall. Once the device is uninstalled, restart your system, and Windows will automatically search and install the latest driver for the device. OPTION 3: Via driver installer. If you have downloaded .EXE or executable driver installer from device manufacturers web site try installing it, if the installation fails, try using compatibility mode for the installer. Navigate where the installer is located, right-click on it, and choose properties. Go to compatibility TAB and try installing it with administrator privileges in Windows 8 mode. Reboot your system after this step. This should solve the issues, however, if the issue still persists, follow the next steps.

2. Verify the Corrupted System Files

   Press WINDOWS + X on the keyboard to open the hidden system menu and choose Command prompt (administrator) In the command prompt type in: sfc /scannow and press ENTER. The scanning process and repair of files will take around 15 min. Leave it to finish completely, do not restart, work on the computer or shut it down while the process is active, and only after it is finished reboot your system.

3. Update Windows.

   If your Windows is not updated sometimes this issue can be resolved by updating it on the latest version. Click on start and then on settings. Once the settings screen is opened, find and click on Update and Security. Go to the Windows update tab and click on DOWNLOAD or click on check for updates for the latest Windows fix.

4. Reset BIOS to factory settings.

   Sometimes BIOS not being properly configured can cause issues in Windows itself and prevent it from detecting PnP devices thus creating this error. Restoring BIOS back to the factory setting can help. Turn off your computer and turn it back on. Press delete, f12, f11, or any other key which will take you to BIOS (default key is delete but sometimes manufacturers map this to another one. Once your screen turns ON you will see in the bottom message which key needs to be pressed in order to enter BIOS). Sadly since every BIOS could be different we can not cover step by step guide for each but you need to find the option where you load BIOS defaults, click on it save, and exit. Your computer will restart and boot into Windows, check to see if the problem still persists.

5. Update BIOS

   BIOS can cause issues with certain PnP devices when the newest Windows update is rolled. If reverting BIOS to the factory setting has not been successful try update. Go to your motherboard manufacturer website, find the update and read step by step guide there since updating BIOS differs from version to version and from manufacturer to manufacturer. After the update is done, restart the computer and hopefully, the error is gone.

6. Perform a System Restore

   If everything else fails, perform a system restore to get Windows back into the state before the update was installed and when everything was working fine. Press WINDOWS + R on the keyboard to open the run dialog. In the run dialog, type control panel and press enter to enter control panel, locate recovery and click on it. Inside the recovery screen click on Open System Restore. Choose a date when everything was working in order, the best bet is the date before Windows update and roll it back. Click on date, and then on next.

As you know, Microsoft Office Word is a program that’s widely used all over the web and it’s because it’s the best program there is when it comes to editing and processing words. However, even when it is the best there is, it is not without its faults and so on as it can still encounter some errors every now and then. One of these errors is the Template_fields errors. When you encounter such an error, you will see a pop-up window. This strange error randomly appears on documents but you need not worry as this post will provide you with possible solutions to resolve the problem. But before you proceed with these solutions, you have to create a backup for all your Word documents to Microsoft OneDrive preferably. To fix the problem, you can try to disable the add-ins or try to start Word in Safe Mode or repair Office. For more details, refer to the options given below.

Option 1 – Disable the Add-ins

Although add-ins enhance Microsoft Word, there are times when they can also cause problems that end up breaking Microsoft Word instead of improving it which is why you have to disable them. Refer to the following steps to do so:

• Open Microsoft Word and then click on File.
• After that, select Options from the menu and then click on Add-ins.
• From there, you’ll see Manage: Com Add-ins as well as a button that says Go.
• Now click on the Go button and wait for a couple of seconds for a new window to appear.
• In the newly opened window, uncheck all the Add-ins and click on OK.
• Restart Microsoft Word and check if the “Template_fields” error is now fixed or not.

Option 2 – Try starting Word in Safe Mode

You might also want to try rebooting Microsoft Office in Safe Mode as it is one of your best shots in finding out whether the problem is internal or external. However, if the problem does not appear after you reboot Microsoft Word in Safe Mode, then there is a possibility that the problem is with Microsoft Office itself. On the other hand, if the problem persists, then it could be a deeper issue.

• First, start Microsoft Word in Safe Mode.
• Next, tap and hold the Ctrl key on your keyboard and open the Word document.
• After that, you should see a dialog box. Click on Yes and see if Microsoft Word opens in Safe Mode.
• Alternatively, you can open the search box and then type “winword.exe /safe” and hit Enter.

Option 3 – Try repairing Microsoft Office

If the first two options didn’t work, then you might want to try repairing Microsoft Office without getting rid of it. In most cases, this usually works in fixing any problems and returns the program back to its default state. To repair Microsoft Office, follow the steps below.

• Right-click on the Start Menu button and select Apps and Features.
• Next, scroll until you see the Microsoft Office program you want to repair and then select the Modify option.
• After that, follow the options to repair Microsoft Office and then restart your PC and see if the “Template_fields” error is no longer present.

The Windows Defender program can both scan and monitor almost the entire folder on a Windows 10 computer. So if you have a folder that may have files that could trigger an alarm to Windows Security, then it would be better if you add an exclusion to Windows Security. Note that it is okay to do this as long as you’re certain that the contents of the folder you want to exclude are safe and that Windows Defender is only throwing out warnings for nothing. This way, Windows Defender won’t scan those folders in the future. And besides, there are also some Windows folders and files that you may exclude from the Antivirus scans, especially if you want to save your scan time. This kind of feature also comes in handy when you trust a file type or folder or any process that you believe is safe but the Windows Security considers as malicious. To exclude a folder or a file or process or a file type from the Windows Security scan, here are some steps you can follow. Make sure to do them carefully. Step 1: Search for “Windows Security” in the Search box and then click on it from the search results to open it. Step 2: Next, click on Virus & threat protection > Manage settings > Add or remove exclusions. Step 3: After that, on the next screen, click on Add an exclusion > Folder. It will show you a list that includes File, Folder, File Type, and Process. Step 4: Now click on “+Add and exclusion” on the next window and then select a folder you want to exclude and click OK to add it in the Exclusions list. Step 5: Click on the down arrow button to remove it and then click on the Remove button. Note: If you want to only ignore a few file types, it’s better if you configure your antivirus program to ignore these files with a specific extension. This way, it will ignore all of them no matter what their location is. Also keep in mind that when you select a folder, all the subfolders in it will also be excluded from the scan. Thus, you need to understand what you’re about to do. Once you’re done excluding the folder, it is recommended that you protect the folder using the Controlled Folder Access since this folder is not monitored for threat. The Controlled Folder Access will ensure that an external program does not alter it. This way, you can be sure that even though this folder is not included in the scan, it is still secure.

The Internet has become an essential human right as stated in many countries around the world. Among many benefits that the internet offers are various sites selling Stock photographs for all of your needs. No matter are you working in the design industry or just want to make something for yourself there is a high chance that you will eventually need some photos for your work. In this article we are going to go through the best Stock Photo sites BUT, we will focus on ones that give you royalty-free Photos, so no paying stuff here, just the best of the free world.

Adobe Stock free collection

https://tracker.tradedoubler.com In the last year of 2020, Adobe has made more than 70000 photos, videos, illustrations, and templates completely free. You are free to use provided material for personal, commercial, and creative work. Since this is adobe’s collection, well part of it, all of the given material is of high quality.

Unsplash

https://unsplash.com/ Unsplash is a place where you will go if you want to find free-quality pictures. Since a lot of photographers are donating their selected work there you will find always consistently high-quality work there. Unsplash also has applications for Android and iOS so you can go through their stock on your mobile device as well. Photos are organized into categories that make searching much easier.

Pixabay

https://pixabay.com/ Pixabay is maybe well known due to its huge collection of both images and illustrations. There are tons and tons of stuff in there all royalty-free for use. The bad side is due to its strongest one, since there are so many images on its site, quality is not always top-notch like on Unsplash for comparison but you might find stuff here that you will not be able to do it anywhere else.

Pexels

https://www.pexels.com/ This is a great choice for web or app developers since you can find various UI ideas and designs on it. Many UI ideas ready for implementation will be found here and a decent amount of photos as well. The overall site is great for that purpose but please do read the license on each image since some of them are limited in use and cannot be used in commercial projects.

Pikwizard Stock

https://www.pikwizard.com/ Stock photography from Pikwizard is a place where you will go if you need high-quality pictures of people. There are a lot of images of people in natural poses doing things, nothing cheesy or unnatural, just pure and great-looking ones. Among other things is also a vast selection of cityscapes. Sadly as in the case of Pexels, not all pictures have the the same license so make sure to check terms of use before using one.

Gratisography Stock photos

http://gratisography.com/ Last on our list is a Stock site with a strange name and if you visit it you will see that it is not just the name that is strange. Gratisography is a stock site that aims to provide you with high-quality photographs but in different take from another site. These images are more artistic and surreal than other competitor sites. Images are uploaded almost on daily basis but since thematic is somewhat niche collection itself is relatively small.

Windows 11 is a good-looking operating system but people love to make things personal and to their liking so we decided to help you in this mission with small customization of changing default system fonts inside Windows 11.

Since there is no really easy way to just switch the font windows is using for itself we will have to tweak a registry a little so before we start please do make a backup of the registry file and follow the steps as they are presented in order to avoid any errors and break the system.

So, if all precautions are made and you are ready to change your Windows appearance let's dive right into it:

Find and/or install the font that you wish to use

There are vast free font sites on the internet where you can find fonts that you like and wish to use but be very careful with your desired font selection. The font that you choose needs to be a complete typeface, meaning that it has to contain all glyphs, large and small font sizes, all special characters, etc or you will experience that in certain areas nothing will be displayed.

Once you have found the font that you like and made sure it is a complete font, install it on your system (you can skip this step if you just want to change the system font with one already installed on your system)

Create REG file

Open notepad or a similar plain text editor in order to create a file that will apply changes directly into the registry and create a new file. Inside the file paste this text:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
"Segoe UI (TrueType)"=""
"Segoe UI Bold (TrueType)"=""
"Segoe UI Bold Italic (TrueType)"=""
"Segoe UI Italic (TrueType)"=""
"Segoe UI Light (TrueType)"=""
"Segoe UI Semibold (TrueType)"=""
"Segoe UI Symbol (TrueType)"=""

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]

"Segoe UI"="NEW-FONT"

All the way to the bottom where it says: "Segoe UI"="NEW-FONT", change NEW-FONT with the font name that you have chosen or installed in the previous step. For example: "Segoe UI"="Ubuntu".

Now go to File > Save As and name your file however you want but give it REG extension so it looks like: my_new_windows_font.REG

Apply changes

Now that you have your registry entry saved, locate it and double-click on it, at this stage Windows warning will probably pop up, you can just ignore it and click on YES since you wrote the file and know what it is. After registry entry is applied reboot your PC in order for changes to take effect.

Rolling back

If you want to change the font to another one, just repeat this procedure again. If you want to roll back to using the default Windows font, repeat the process but with this code instead of the one provided in the REG file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts]
"Segoe UI (TrueType)"="segoeui.ttf"
"Segoe UI Black (TrueType)"="seguibl.ttf"
"Segoe UI Black Italic (TrueType)"="seguibli.ttf"
"Segoe UI Bold (TrueType)"="segoeuib.ttf"
"Segoe UI Bold Italic (TrueType)"="segoeuiz.ttf"
"Segoe UI Emoji (TrueType)"="seguiemj.ttf"
"Segoe UI Historic (TrueType)"="seguihis.ttf"
"Segoe UI Italic (TrueType)"="segoeuii.ttf"
"Segoe UI Light (TrueType)"="segoeuil.ttf"
"Segoe UI Light Italic (TrueType)"="seguili.ttf"
"Segoe UI Semibold (TrueType)"="seguisb.ttf"
"Segoe UI Semibold Italic (TrueType)"="seguisbi.ttf"
"Segoe UI Semilight (TrueType)"="segoeuisl.ttf"
"Segoe UI Semilight Italic (TrueType)"="seguisli.ttf"
"Segoe UI Symbol (TrueType)"="seguisym.ttf"
"Segoe MDL2 Assets (TrueType)"="segmdl2.ttf"
"Segoe Print (TrueType)"="segoepr.ttf"
"Segoe Print Bold (TrueType)"="segoeprb.ttf"
"Segoe Script (TrueType)"="segoesc.ttf"
"Segoe Script Bold (TrueType)"="segoescb.ttf"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes]

As you already know, the Windows Sandbox is one of the new features in Windows 10. However, just like other new features, it also throws up errors and one of them is the error that states,

“Windows Sandbox failed to start, Error 0x80070057, The parameter is incorrect”.

This particular error in Windows Sandbox occurs due to its dependence on numerous components of Windows 10 that are related to Hyper-V and Virtualization mainly. To fix this error, there are several options you can check out. You can try to install any pending updates on your Windows 10 computer, as well as make sure that all the services related to Windows Sandbox are enabled.

Option 1 – Try to run the Windows Updates to install pending updates

The first thing you can do to resolve the “Windows Sandbox failed to start, Error 0x80070057” is to check Windows Updates in your computer and see if there are any pending Windows Updates you have to install. All you have to do is go to the Windows 10 Settings app and then go to the Windows Updates section and click on the “Check for updates” button to check if there are any pending updates that are needed to be installed. This could fix the Windows Sandbox error.

Option 2 – Ensure that all the supporting processes and services are running properly

If running Windows Sandbox as an administrator didn’t fix the error, you have to ensure that all related processes for Windows Sandbox are running properly. To do that, follow these steps:

• Tap the Win + R keys to launch the Run utility and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
