Recently, a number of users reported that they were not able to use the “Run as administrator” context menu option when they tried using it or opening a program with administrator privilege. If you are one of these users facing this problem, then you’ve come to the right place as this post will guide you in fixing this issue. At the time of writing, it isn’t clear what the cause of the issue is but there are potential fixes you can try to fix the problem. You can try turning on the User Account Control or clean up the Context Menu items change the Group Membership. On the other hand, you can also perform both SFC and DISM scans via Command Prompt or troubleshoot the problem in a clean boot state as it is possible that some third-party programs are the ones that are causing the problem. You could also run an anti-malware scan using Windows Defender or your antivirus program.

Option 1 – Try to turn on the User Account Control

When you open a program with administrator privilege, the User Account Control or UAC prompt will pop up asking you to confirm the permission. However, if you have disabled the User Account Control by mistake or some malware has disabled it, then it’s no wonder why the “Run as administrator” option is not working. Thus, you need to check if UAC is turned on or not. All you have to do is go to the User Account Control settings.

Option 2 – Try changing the Group Membership

• First, you need to sign in with your administrator account or ask your administrator to sign in for you. So if you only have a Standard User account, you have to add that account to the Administrators group.
• In the taskbar search box, type “netplwiz” and check the search results.
• From there, select your user account and click the Properties button.
• After that, go to the Group Membership tab and select Administrator.
• Now click on the Apply and OK buttons to save the changes made and then sign in to your computer again and see if the “Run as administrator” option is working or not.

Option 3 – Try to create a new Administrator User account

If you have a standard account, you can try creating a new account but this time, you create an administrator user account and then see if you can now use the Run as administrator option or not. Note that you have to sign in with your main account before you can create an admin account.

Option 4 – Run the DISM tool

You can run the DISM tool as well to help fix the problem with the “Run as administrator” option. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /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.

Option 5 – Perform a System File Checker scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the problem with the “Run as administrator” option on your Windows 10 computer. 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.

• Once done, restart your computer.

Option 6 – Put your computer in a Clean Boot State

You can also troubleshoot the problem in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing you from using the “Run as administrator” option and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try to use the Run as administrator again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• 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.)
• After you’ve set your computer into a Clean Boot State, try to check if the error is now fixed and that you can now view the Properties.

Option 7 – Try scanning your computer using Windows Defender

As mentioned, if your computer was recently infected with some malware, it is possible that the malware changed the User Account Control settings which is why you’re not able to use the Run as administrator option. Thus, you need to scan your computer using Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

After the command you entered has successfully run, you will see a message saying, “DllRegisterServer in vbscript.dll succeeded.”

On the other hand, if re-registering the DLL file didn’t work, you might have to log on to your computer using an administrator account and then try re-registering the DLL file once more. But before you do that, you need to create a system restore point first so that if anything goes wrong, you can always undo the changes you’ve made. After creating a system restore point, double-click on the downloaded .reg file to add its contents to the Registry. After that, try opening the program you were trying to open but weren’t able to because of the error. If it doesn’t work, you can always reinstall the affected programs that throw up the error and see if it resolves the problem. You could also seek the help of a one-click solution to fix the problem for you.

They also come from add-on applications, also referred to as browser helper objects (BHO), browser extensions, or toolbars. Sometimes you may have mistakenly accepted a browser hijacker as part of a software program bundle (usually freeware or shareware). Typical examples of browser hijackers include CoolWebSearch, Conduit, RocketTab, OneWebSearch, Coupon Server, Searchult.com, Snap.do, and Delta Search.

Tips on how to remove browser hijackers

Certain browser hijacking can be easily stopped by discovering and eliminating the corresponding malware application from your control panel. However, certain hijackers are more difficult to find or eliminate as they might get themselves associated with certain crucial system files that enable it to work as a necessary operating-system process. You should think about carrying out manual repairs only if you’re a tech-savvy person because there are possible risks associated with fiddling around with the system registry and HOSTS file.

If you suddenly encounter Activation Error codes such as 0xC004E016, 0xC004F210, 0xC004F034, and 0xC004F00F on your Windows 10 computer, then they all point to the same issue – Invalid Product Key or Version mismatch. When you see any of the aforementioned error codes above, it indicates that you are either entering a wrong product key or you are using an incorrect ISO when installing it on your computer. In such cases, you may see either of the following error messages:

“You are running Windows 10 Pro, but you have a valid digital license for Windows 10 Home.” Or: “The specified product key is invalid or is unsupported by this version.”

If you got the error code 0xC004F00F then it means that you’ve entered a product key for the Enterprise edition of Windows to activate Windows 10 Pro or Windows 10 Home. It could be that you have a key from your work and you accidentally use it on your Home PC. If you got the error codes 0xC004E016, 0xC004F210, then it means that you have entered a product key that is meant for a different edition or version of Windows. On the other hand, if you got the error code 0xC004F034 instead, then it means that you have entered an invalid product key or a product key for a different Windows version. Whichever error codes you have, refer to the possible solutions given below to fix the Invalid Product Key or Version mismatch Activation Error in Windows 10.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve this Activation error 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.

Option 2 – Try purchasing a new license

There is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect to your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

Option 3 – Try activating Windows 10 via mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

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.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• 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.

The use of Biometrics is supported by Windows 10. Aside from that, it also supports PIN, password, picture password on all computers and if your computer has the proper hardware, Windows 10 also supports facial scanning, iris scanning, and even fingerprint scanning. You can see all these exciting features inside Settings > Accounts > Sign In Options. On the other hand, you can’t really expect to make use of all the above-mentioned features since it depends if the hardware is available to support them. One of the most interesting features is the use of Biometrics which is really useful in workplaces and so this post will show you how you can enable or disable the Domain Users Sign In on Windows 10 using Biometrics via Registry Editor or Group Policy Editor. But before you go on, you need to create a System Restore Point first since the modifications you’re about to do might affect the functioning of your computer.

• Afterward, click on “Domain Accounts” and set its value to “1”. This will allow the domain users to sign in to Windows 10 using Biometrics. While the value of 0 will disable the domain users sign in to Windows 10 using Biometrics.
• Exit the Registry Editor and restart your computer for the changes to take effect.

Option 2 – via Group Policy Editor

• Tap the Win + R keys to open the Run dialog box.
• Next, type “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.
• After that, navigate to the following setting:

Computer Configuration > Administrative Templates > Windows Components > Biometrics

• Then double click on the following entries located on the right-side panel and set the radio button to Enabled on all of them.
