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.

Option 1 – Try to restart the Credential Manager Service

• Go to the Start menu.
• Then type in “services” in the search box.
• From the search results, right-click on “Services” and select the “Run as Administrator” option.
• Next, look for the Credential Manager Service in the Services window.
• Once you found it, double-click on it to open its Properties. From there, you need to click on the Stop button.
• After that, set the Credential Manager Service to “Automatic” and click on the Start button to restart it.

Option 2 – Try to start the Application Information Service

You can also try starting the Application Information Service to fix the “Error 1061 The service cannot accept control messages at this time”. Just open the Windows Services Manager and make sure that Application Information Service is Started. And if you find that it’s already started, you need to restart it.

Option 3 – Try killing the IIS Worker Process via Task Manager

• Tap the Ctrl + Alt + Del keys and select the Task Manager.
• Next, click on More details to expand the Task Manager and then look for the IIS Worker Process entry which should be displayed in the list under the Processes tab. From there, you can see it in the Background processes. Once you find it, kill its process.

If you got an error message saying, The INF file you selected does not support this method of installation while trying to install a driver using the “Install” option in the right-click context menu, read on as this post will guide you in fixing the problem. The INF file mentioned in the error message is a text file that’s divided into different types of formatted sections. Each one of the sections is designed for a particular purpose. For instance, one section is designed to copy files or to add entries to the registry. INF files are used to install drivers. However, if something is wrong, you might encounter this error while installing a driver on your Windows 10 computer. To resolve this problem, you can try to download the driver again from the official manufacturer website or check if the driver is compatible with your computer’s operating system architecture or you can also try installing the driver from the Device Manager. For more details, follow the given options below.

Option 1 – Try downloading the driver again from the official website of the manufacturer

Usually, you shouldn’t encounter this kind of issue no matter what installation method you used on your Windows 10 PC. However, there are times when the driver itself is corrupted for some reason which is why you are unable to complete the installation and receive an error message instead.

Option 2 – Try checking if the driver is compatible with the OS architecture

It is possible that you’re getting this error if you have a driver that is compatible with a 32-bit system and you are trying to install it on a 64-bit system and vice versa. Thus, you need to check if the driver you are trying to install is compatible with your operating system if you haven’t done it when you’ve downloaded the driver from the website of the manufacturer. To check the system architecture, in the Start Search, type “msinfo32” in the field and hit Enter to open the System Information window. From there, you should see all the information about your operating system. In addition, you can also search “system information” in the Cortana search box and look for the System Type entry and open it.

Option 3 – Try installing the driver from the Device Manager

If you have the driver files on your PC and you have to update a driver, refer to the steps given below to be guided on how to install the driver from the Device Manager.

• 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 driver you want to update, and then right-click on each one of them and select the Update Driver from the menu.
• After that, click on the “Browse my computer for driver software” option.
• Next, select the “Let me pick from a list of available drivers on my computer” option and then click the Next button.
• On the next screen, you should see the “Have Disk” option. Click on this option and then click on the Browse button to go to the location of the file. After that, you shouldn’t have any problem installing the INF file.

Option 4 – Try running the System File Checker Scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the “The INF file you selected does not support this method of installation” error. 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. To run the SFC command, follow the steps given 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.

 Now restart your computer.

If you are using your computer and you notice that Hard drive shows high space utilization even if you only have a few applications installed on your computer, then you’ve come to the right place as this post will guide you on what you can do to sort this problem. Upon noticing the odd state of your hard drive and you check the actual volume that’s occupied by the apps in your drive and you see that they are not really occupying a lot of space. This kind of issue could indicate that your hard drive is not showing the correct value for the free storage space of the drive-in your Windows 10 computer. This kind of problem could be passed off as a system bug, however, it could also be a serious problem. In fact, as you are aware, there are hidden folders and files in your computer that could be occupying space and since most of them are associated with system applications, you might not realize it unless you thoroughly check the folders.

The most common causes of the issue are as follows:

1. The system information folder might be utilizing a lot of space. If you wonder where the information for the system restore points is stored, they are stored in the system information folder which in turn is stored in the drive as a hidden file.
2. An issue with system maintenance could cause the problem.
3. Malware or some other software might have created an undetectable hidden file.
4. Space could be occupied by the trashbin folder.
5. These hidden files could occupy significant space in the folder, thus slowing down the system and impacting its performance. If you face this issue, try our suggestions and see if they help you.
6. Run ChkDsk
7. Clear all Junk files
8. Reduce the space occupied by the system restore points
9. Run the System Maintenance troubleshooter

Option 1 – Run CHKDSK utility to check the drive for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. To use it, follow the steps below.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]

Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.

Option 2 – Try to delete the temporary files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space: 
  • Windows Upgrade Log Files
  • The system created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
• Now go to the “Free Up Space Now” section and click the Clean Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix the error.

Option 3 – Try to reduce the space occupied by the system restore points

In case you don’t know, system restore points actually occupy a significant space in your computer which is stored in the System Information folder. Thus, you need to check the size of this folder and unhide the folders and files and then click on the folder. The size of the folder should be displayed in the right pane of the window. To fix the storage space problem, you could delete all the old System Restore Points as well as Previous versions of files or you could also restrict the disk usage of the System Restore points.

Option 4 – Try to run the System Maintenance troubleshooter

The problem could also be caused by the System Maintenance and to fix it, you have to run the System Maintenance troubleshooter by following these steps:

• In the Windows Search bar, type “control panel” and double click on Control Panel from the search results.
• Next, go to this path: Control PanelAll Control Panel ItemsTroubleshootingSystem and Security.
• After that, click on the System Maintenance troubleshooter to run it.
• Once the process is completed, restart your computer.

NDIS or Network Driver Interface Specification is a programming interface for the network interface cards that aids in the proper functioning of a system driver in a computer network. The NDIS helps the computer system in order to communicate with other connected devices and hardware components on a computer network. In relation, the ndis.sys file is a critical system file developed by Microsoft for the Windows operating system. As you know, sys files or system files are important parts of the Windows operating system as well as a repository of system driver settings used by Windows to communicate with the connected hardware and devices. The ndis.sys files are stored mostly in a driver folder at C:/Windows/System32/drivers and as mentioned, these files are essential for the system to function properly. Although the presence of ndis.sys system file is not yet known to affect the normal functioning of the Windows OS, some of the Windows 10 users reported that they encountered ndis.sys blue screen errors on their PCs. Blue Screen of Death errors or Stop errors usually occurs when you open a program or a function. Moreover, it could also occur when the driver gets loaded during the system startup or during system shutdown. It isn’t yet clear what really causes the ndis.sys blue screen error. However, like other Stop errors, it may occur due to corrupted files, misconfigured device drivers, bad drivers, corrupted Windows Registry, missing or damaged system files, and malicious programs. Aside from the aforementioned reasons, the ndis.sys blue screen error might also occur if your hard disk is damaged and if the RAM is corrupted. In such cases, a lot of users usually disable the ndis.sys file. However, it won’t really resolve the issue since the file is required for the normal functioning of the operating system and even when you disable the file, it’s pretty useless as the file will start all over again. In addition, you might want to disable security programs or firewalls and antivirus programs in the meantime to check if these programs are the ones that are causing the error. And if you’ve determined that none of the security programs or firewalls and antivirus programs are to blame, refer to the options below that might help you resolve the DRIVER_IRQL_NOT_LESS_OR_EQUAL or ndis.sys Blue Screen of Death error.

Option 1 – Try to update or reinstall the PC device driver

The Ndis.sys Blue screen error can occur when the device driver in your computer is outdated or corrupted. Thus, you either have to update or reinstall it to fix the issue.

• Tap the Win + R keys to launch Run.

• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Option 2 – Rollback your Network drivers

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Next, select the driver entries that are labeled appropriately other than anything in the context of the WAN Miniport.
• Then select each one of them and double-click to open a new mini window.
• After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of your Network adapters.
• Now restart your computer to successfully apply the changes made.

Option 3 – Try running the System File Checker

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the ndis.sys Blue Screen of Death error. 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. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.

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 4 – Try running the CHKDSK utility

Running the CHKDSK utility might also help you resolve the Netwtw04.sys failed BSOD error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 5 – Run the DISM 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
• The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.
• Restart your PC.

Option 6 – Perform a System Restore

Performing a System Restore on your computer can also help you fix the ndis.sys Blue Screen of Death error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Windows comes with a built-in backup solution. However, if it failed because of an internal error, you will encounter an error message saying, “The backup application could not start due to an internal error, Server execution failed (0x80080005)”. When you get this kind of error, it means that it did not start and the process failed with a Server execution error. If you got this kind of error worries not for this post will guide you in fixing the problem in your Windows 10 computer. The Windows Backup service is an excellent feature in Windows that only works on the NTFS file system and if you want to use this make sure that you have formatted your files system to NTFS. It is performed by the Volume Shadow Copy, all you have to do is right-click on any folder and if you see the “Previous versions” option, this means that a backup process runs from time to time and can bring back old files when needed. To resolve the “The backup application could not start due to an internal error”, here are two suggestions you can check out.

Option 1 – Check if the Volume Shadow Copy service is running and restart it

The first thing you need to do is check if the Volume Shadow Copy service. To do that, refer to the following steps:

• Then select the “Run as administrator” option to open Command Prompt with admin privileges.
• After that, type “net stop sdrsvc” and hit Enter to execute the command in stopping the Volume Shadow Copy service.
• Next, type the “net start sdrsvc” command and hit Enter to start the service again.

Note: You can also restart the service using the Windows Services Manager.

• 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.
• From there, look for the Volume Shadow Service (sdrsv) from the list of services. Its Startup type should be set to Manual by default.
• Restart the service and if you don’t encounter any error while you turn it on, re-run the backup service and see if the backup process runs successfully.

Option 2 – Try to run the Volume Shadow Copy Service in a Clean Boot State

If the first option didn’t work and the service still keeps on failing even though the service is running, you can try putting your computer in a Clean Boot State and then try to run Windows Backup again.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to run the Volume Shadow Copy service again and see if the process goes smoothly.

Note: You might also want to delete all the files in the backup solution if you want to start fresh with the backup solution. Just go to C:/System/Volume/Information/Windows Backup and take ownership of the folder. After that, make sure to stop the Volume Shadow Copy service and then delete all the files inside it.

As you know, the Taskbar is one of the integral parts of the Windows desktop and it has been there since the release of Windows 1.0 and up until now with Windows 10.

As you know, you can find the number keys in two spots on your keyboard – one is above the letters while the second one is at the number pad. Recently, a number of users reported not being able to type any numbers on their keyboards while some reported that their keyboards only type numbers. This issue could occur on both sets of the number keys or on the one at the number pad. This is a rare situation and seldom happens to users. So if you are one of the few who experience the same problem then you’ve come to the right place as this post will guide you on what you can do to fix the keyboard issue. This issue is most likely due to a switched-off number pad, outdated or corrupted keyboard drivers, turned on mouse keys or it might have something to do with the physical connections. Whatever the cause is, here are some options you have to try to resolve the problem.

Option 1 – Try to enable Numlock

The first thing you can do to fix the issue with the keyboard is to enable the Numlock since one of the most common reasons for this kind of problem is where the keyboard won’t type numbers because the Numlock key is disabled. Thus, you have to enable this key by pressing it once to enable the number pad.

Option 2 – Turn off the Mouse key

• From the Start Menu, go to Control Panel.
• Navigate to Ease of Access Center.
• Then select the option “Make the keyboard easier to use”.
• Navigate to the option “Control the mouse with keyboard” and then uncheck the “Turn On Mouse Keys” option to turn off the Mouse key.
• Click on Apply and then on OK to save the changes made.

Note: The problem with the keyboard could stem down to a simple issue in its settings so if you have successfully followed the steps for this solution then you should be able to fix the problem.

Option 3 – Reinstall, update or rollback your keyboard driver

Once you’ve determined that the problem is in the software part of the keyboard, it is now time to try to reinstall, update or roll back your keyboard drivers. To reinstall the driver for your keyboard, refer to these steps:

• From the WinX Menu, open the Device Manager.
• In the Device Manager, you should find your laptop’s keyboard under the “Keyboards” option. Right-click on it and select the “Uninstall” option.

Note: If you’re not quite certain about your laptop’s keyboard, you can uninstall all the keyboards if there’s more than one.

• After that, restart your PC and see if the keyboard driver is installing automatically. If not, open the Device Manager again and right-click on Keyboards, and select the option “Scan for hardware changes” to install it.

Once the keyboard driver is installed again, check if your keyboard is now working properly or not.

Option 4 – Try connecting the keyboard to a different USB port or another computer

The problem might have something to do with the USB port that’s currently in use by your keyboard. It could be that it’s not working so it makes sense to unplug it and attach it to another USB port. You can also clean the USB port on both ends to ensure that they are not affected by corrosion. In addition, you can also try connecting the keyboard to a different computer and see if the Shift key works there or not.

Option 5 – Try to check your connections

You can also try checking if the connection mode you are using for your keyboard is functioning properly. For instance, if you are using a Surface 2-in-device, you can clean the connection pins and see if it resolves the problem.

Option 6 – 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 Keyboard 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.
