If you are trying to run or starting a program on your Windows 10 computer and you suddenly get an error message saying, “Error 1061 The service cannot accept control messages at this time”, read on as this post will show you what you can do to fix the problem. This kind of error pops up since the Application Information Service does not respond to the requests to raise applications to Administrator in Windows 10 like the Task Manager, Service updates, and so on. Thus, you won’t be able to run or open apps and will only get stuck with this error. The “Error 1061 The service cannot accept control messages at this time” message is a type of network error that typically occurs when there is a temporary mismatch between the requested control and the state of the service to be controlled. It’s most likely that the service is in a state of start-pending, stop-pending, stopped or it may already be used by another user which explains why this error message suddenly appears. You can encounter this error message on any Windows operation. Here are some of the most common occurrences:

• Debugging a Windows service
• Starting Task Manager
• Starting Registry Editor
• Starting Firewall
• Starting services.msc
• Starting dsm.exe
• Updating services
• Asking for file permissions, etc.

According to Microsoft MSDN, the error occurs because:

“There is a temporary mismatch between the requested control and the state of the service to be controlled. The service may be in a state of start-pending, stop-pending, or stopped. Wait a few minutes, then retry your operation.” If after a few minutes, the error still appears, then you may have to follow the options prepared below.

AMD and ATI Technologies ULC have filed a complaint in the United States International Trade Commission against Realtek Semiconductor and TCL Industries Holdings claiming that they have violated five patents.

The complaint has automatically triggered an investigation from USITC which has responded that they will look into certain graphics systems, components thereof, and digital televisions with components from Taiwan-based Realtek and the China/Hong Kong-based TCL Industries Holdings (and its subsidiaries).

AMD and ATI are seeking an exclusion order and cease and desist orders for the sale of the products. The investigation officially started on July the first. AMD and ATI claim that Mediatek and TLC Industries violated five patents on various technologies used in graphic cards.

The ATI patents include texture decompression techniques, a graphics processing architecture with a unified shader, and a multi-threaded graphics processing system (patents 7,742,053 claims 1-9, 8,760,454 claims 2-11, and 11,184,628 claims 7-12). The AMD patents cover a method and system for synchronizing thread wavefront data and events. A patent covers a processing unit that enables asynchronous task dispatch (patents 8,468,547 claims 16-21, and 8,854,381 claims 15-20).

This is not the first time AMD and ATI have asked for a USITC investigation, in 2017 they were targeting LG, Vizio, Mediatek, and Sigma Designs. The previous investigation has been concluded with the settlement between parties, how this one will go we shall see and keep you updated as we move along.

In this post, we will discuss what the “ bootres.dll ” file is in the Windows 10 operating system and where it’s also located. In addition, you will also be guided on how you can replace or fix a corrupt bootres.dll file which may prevent you from booting to your Windows desktop and will display an error message instead saying, “Boot critical file resourcescustombootres.dll is corrupt”. There are times when this error might also boot your PC to the Automatic Repair screen. DLL files, also known as Dynamic Link Libraries are external parts of applications that run on Windows as well as other operating systems. Almost all applications are not complete in themselves and store code in different files so if there is a need for the code, the related file being called by a certain application is loaded into memory and used. If the software or the operating system is unable to find the concerned DLL file or if the DLL file ends up getting corrupted, you will most likely get an error message. In case you don’t know, the bootres.dll file is a critical system OS file, size 90KB, and can be found in the Windows folder. It is a part of the Boot Resource Library and portrays an important role in making sure that your PC boots properly. So if it ends up getting corrupted, your PC may fail to boot correctly and you’ll get an error message instead. To resolve this problem, here are some suggestions that might help. If your PC automatically boots to the Automatic Repair screen, you need to click on that option to run the Automatic Repair. If it doesn’t work, you have to boot into the Advanced Startup options to manually access and run the Automatic Repair. Once you’re in the Advanced Options, you will be able to:

• Run Automatic Repair
• Use System Restore
• Start Windows from an external device
• Access Command Prompt
• And use the System Image Recovery to restore Windows from a Factory image.

If the Automatic Repair fails to fix the problem, you may have to use System Restore or the Command Prompt to carry out further troubleshooting steps. Refer to the guide below to use these tools.

Option 1 – Try running the System File Checker in Safe Mode

Running the System File Checker is the safest way to fix DLL file missing or corrupted errors are thrown up by the Windows operating system as it could give you better results. 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 that might be causing the Machine Check Exception BSOD error. To run the SFC command, follow the steps given below.

• Boot your PC into Safe Mode.
• 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.

Option 2 – Try running the DISM tool to repair the System Image

To repair the System Image, you need to use the DISM or Deployment Imaging and Servicing Management tool. The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

• Open the Command Prompt as admin.
• Then type in this command: Dism /Online /Cleanup-Image /RestoreHealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Note: The command you executed will check for Windows component store corruption and will restore its good health. The scan might take up to 15 minutes. Once it is done, you have to restart your computer.

Option 3 – Try to repair the MBR and rebuild BCD

To repair the MBR and rebuild BCD, follow these steps: The problem might boil down to the Master Boot Records since the previous case has already been isolated. There are times when the Master Boot Records can get corrupted and even though it is a serious issue, it can still be rectified by repairing the Master Boot Record.

• Tao the F8 key while booting the system to go into the Windows Recovery Menu.
• Next, click on Troubleshoot.
• Then click on the Advanced options to get into the Automatic Repair menu.
• After that, you have to use the bootrex.exe tool, so click on the command prompt and type in the following commands, one after the other:

Note: “C” is the drive root drive so it could be changed if you’re using a different one.

Option 5 – Try resetting your PC

Go to the Advanced Options > Troubleshoot > and select the Reset This PC option from the menu and then select Keep my files.

It is common knowledge that when you open a file that contains viruses, it will automatically infect the operating system. This is why most antivirus programs like Windows Defender won’t allow the opening of a file or execution of any associated program if they detected that the file or program could potentially harm the computer. In situations like this, you may get an error stating, “Operation did not complete successfully because the file contains a virus”. In addition, it is also possible that this error message can pop up even for known programs. To open the program or file that triggered the error, you will be given a couple of options in this post but make sure that the program or file is really safe to open and does not contain any virus. You can open the file or execute the program by disabling the Windows Defender or any antivirus program temporarily. You could also try to add an exclusion in your antivirus program or repair File Explorer or run the Disk Cleanup tool. For more details, refer to each one of the options provided below.

Option 1 – Try to temporarily disable the Windows Defender program

Although you could encounter this error with any antivirus program, it is more common in Windows Defender. Thus, you can try to disable it for a while when you open the file or execute the program. To do so, follow these steps:

• First, click on the Start button and go to Settings > Update and Security > Windows Security.
• Here, select the “Open Windows Security” option located in the right pane.

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]

"Segoe UI"=-

The fltmgr.sys file or the Filter Manager is the one that’s responsible in making sure that all the file stored in a computer’s hard drive stays on their respective locations and is located in C:/Windows/System32/drivers. Now when you encounter a Blue Screen of Death or BSOD error saying, “Your PC ran into a problem that it couldn’t handle, and now it needs to restart. SYSTEM_SERVICE_EXCEPTION”. This kind of Stop error is due to an error with the driver that’s responsible for enabling the communication between the hardware and the computer. It indicates that this driver allows direct access to the internal hardware from the CPU itself. What’s worse about the SYSTEM_SERVICE_EXCEPTION BSOD error is that there are times when you won’t be able to log in to your computer even after it reboots. However, you need not worry as this post will guide you into fixing this BSOD error. All you have to do is follow the given options below carefully and that before you proceed make sure that you create a System Restore point just in case something goes wrong.

Option 1 – Run the Windows Update

Obviously, since the fltmgr.sys file is a system file from Microsoft, you can try running the Windows Update and see if it fixes the problem or not.

Option 2 – Run the System File Checker

The System File Checker, also known as the SFC scan, is a built-in utility in Windows that can be found in the C:/Windows/System32 folder. This tool allows you to scan and restore any corrupted system files in Windows that might be causing the SYSTEM_SERVICE_EXCEPTION BSOD error. To use this tool, follow the steps 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.

• Restart your computer and then check if it has fixed the error or not.

Option 3 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that 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.

• 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 4 – Check your hardware for any physical issues

There are times when faulty hardware can result in serious problems in the system such as the SYSTEM_SERVICE_EXCEPTION Blue Screen error. Thus, it is highly recommended that you check the internal components of your CPU to find out if there are any problems. And if there is any physical damage, you need to bring that to a technician to get it fixed or have it replaced.

Option 5 – Run the CHKDSK utility

You can also run the Chkdsk utility to resolve the BSOD error. The Chkdsk utility is the one that repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the commands listed below, and don’t forget to hit Enter right after you type in each one of them and if you have installed Windows to some different directory, you must replace “C” with the name of the drive you’ve installed Windows with.
• chkdsk C: /r /x
• chkdsk C: /f

Changing Taskbar location in your Windows 10 is an easy task but lately, Microsoft has removed the option to just drag it to one side of the screen and place it there, now in order to change location we need to do a little more work but do not worry it is not difficult at all. Right-click on the taskbar to open its properties menu in the menu, on the bottom choose taskbar settings. Once the settings dialog opens, on the right side locate the taskbar location on screen. Click on the dropdown menu and choose the desired location for the taskbar.

Microsoft allows its users to download a copy of Windows to install on PCs. However, when you enter the key after the installation and you got the Activation Error 0xC004F212 instead, then it means that the license key and the Windows version you’ve just installed, do not match. When you encounter this error, you will see the following error message on your screen:

“The product key used on this PC didn’t work with this edition of Windows. Activation Error 0xC004F212.”

Every time Microsoft generates a license for a copy of Windows, it is associated with one particular Windows variant. Windows comes in many editions like Enterprise, Home, Professional, and so on. For instance, if you bought a license for Windows 10 Enterprise but you have installed Windows 10 Professional instead, then the activation will surely fail and you’ll encounter the Activation Error 0xC004F212. You will be asked to select which edition you want to install when you reinstall Windows 10 using a digital license. If you opted for an edition other than the one you are licensed to use, then you will most likely get the Activation Error 0xC004F212. If you have purchased your license key from a store or some website, you might want to check back with them about the exact version of Windows. Doing so will help you narrow down the problem. And if you have second thoughts about the license key’s validity, you can just reach out to a Microsoft Support agent to check the validity of the license key. Also, if have bought it from the store, there should be an option to get a refund. That way you can choose to buy the right version of Windows.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation Error 0xC004F212 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try forcing Windows 10 ISO to use the right version

You can also try to force Windows 10 ISO to use the correct version depending on the product key. Note that this option only works between Windows 10 Home and Professional version since they both have a common ISO. So if it’s Enterprise, then this option won’t work for you.

• Extract the Windows 10 ISO files using an extractor.
• Then browse to the folder you created and go to the sources folder.
• From there, you need to create a text file named “PID.txt” and make sure to follow the exact format given below:

[PID] Value=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

Note: “xxxxx” is the KEY to your Windows version.

• Next, you need to create the ISO again or bootable media that will repack everything and then create the Media file. You can use the Media Creation tool for this.

Note: Windows will check the key during the installation and will figure out the right version of Windows.

Option 3 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to update your Windows 10 computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation Error 0xC004F212 a lot easier and faster.
