Calculator is not working in Windows

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. So in case something went wrong, you can always undo the changes you’ve made.

Option 1 – via Registry Editor

• Tap the Win + R keys to open the Run dialog box.
• Next, type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to the following registry path:

HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftBiometricsCredential Provider

• From there, right-click on the right-side panel and click on New > DWORD (32-bit) Value.
• And then set the name of the newly created DWORD as “Domain Accounts”.
• 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:

Sometimes, some applications after they are installed will put their shortcut in the context menu (right-click on desktop) for easy access, most of the time these are some system tied applications like AMD and Nvidia control panels or archives like WinRAR or 7ZIP but it can happen even for some usual application to do this.

There are some applications that you use frequently and they could be worth putting in the context menu, if you want to avoid clutter on the desktop or in the taskbar this is the third place that you should consider placing shortcuts.

Doing this will require some playing and tweaking in the Windows registry editor so be careful when editing the registry since bad entries can lead to system crash or instability. Follow step-by-step instructions.

Adding apps to the context menu in the registry

Creating entry

Open the registry editor by searching Regedit and pressing enter than inside of the registry editor search for the next key:

HKEY_CLASSES_ROOT\Directory\Background\shell

Select shell and right-click on it, hover over New and in the submenu click on Key. In the next step, you need to name a key, this name will be the thing that will be shown in the context menu when you right-click on a desktop so type in the name that you would like or the name of the application that you wish to add to the menu.

If you wish you can even add a keyboard shortcut to launch this specific application. To do this select entry that you have created and edit the default value, inside the edit string in the Value data field type first & and after that key that you would like as a shortcut. Now after right click if you hit your shortcut key app will be launched right away.

Adding command

The next task is to create a command key that will actually hold the command to launch the application. Right-click on the entry that you have created, hover over New, and click on Key.

Next, you’ll need to create the command key that will actually hold the command used to launch the application. Right-click on the new Notepad key, and then choose New \ Key from the menu. Name this key 'command', all in lower case and without hyphens.

Now in order to finish setting the launcher, you need the full path of the file that you would like to run. Locate your file in file explorer or in another tool and copy its path by SHIFT + right-clicking on the file itself and choosing copy as path option.

Now click on the command key and double click on the default key on right to edit it, inside the field value data paste your path to executable. close and save the registry and you are done.

If you are trying to run Windows Update but encountered an Error 0x80070003, read on as this post will guide you on how you can fix it. This kind of error in Windows Update can occur when you activate Windows Firewall or download from the Windows Store. This kind of error indicates that the Windows Update service or WUAUSERV is not started or that the Background Intelligent Transfer Service or BITS can’t be started. Aside from that, you can also encounter this error with the other Windows Update components. To fix the Windows Update error 0x80070003, you can try to run the built-in Windows Update troubleshooter or replace the old Configuration file named “Spupdsvc.exe”. You can also try to reset the Windows Update components or check the status of all the Windows Update-related services, as well as run a System File Checker scan.

Option 1 – Run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like error code 0x80070003. To run this troubleshooter, Refer to these steps:

• Next, select Windows Update and click the “Run the troubleshooter” button and wait until it’s finished, and then try to run Windows Update again.

Option 2 – Try replacing the old Configuration file named “Spupdsvc.exe”

The next thing you can do to fix the Windows Update error is to replace the Spupdsvc.exe file. This is a process file that comes under the Microsoft Update RunOnce service. So when an update becomes available for your computer, the process responsible for performing the upgrade is notified. In addition, the RunOnce entry is also added to the registry for the spupdsvc.exe and this process is executed when your computer restarts and when you log on.

• In the Start Search, type “command prompt” and from the search results, right-click on Command Prompt and select the “Run as administrator” option.
• Next, execute this command to replace the old configuration of the Spupdsvc.exe file with a new one: c m d (remove spaces on CMD) /c ren %systemroot%System32Spupdsvc.exe Spupdsvc.old
• After that, try to run Windows Updates again and check if the error is now gone.

Option 3 – Try deleting the files from the SoftwareDistribution folder and resetting the Catroot2 folder

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to the steps below.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer.

Option 4 – Check the status of some Windows Update Services

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter or click OK to open Services.
• From the list of Services, look for the following services and make sure that their Startup type is as follows:
  • Windows Update – Manual (Triggered)
  • Background Intelligent Transfer Service – Manual
  • Cryptographic Services – Automatic
  • Workstation Service – Automatic
• After that, check if the Service status of the listed services above are set to Running. If they’re not, click on the Start button to start these services and then check if the Windows Update error 0x80070003 is now fixed or not.

Option 5 – Run the System File Checker Scan

If manually resetting the Windows Update components didn’t work, you can run a System File Checker scan instead. It is a built-in command-line utility that replaces bad and corrupted system files with good system files that might be the cause why you’re getting the error when you try updating your computer. 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.

• Restart your computer.

Google's Pixel smartphone is one if not the best Android smartphone on the market. It regularly gets updates and Google is really trying to keep it as a top choice for Android smartphone users. One of the new things that Google has released for its smartphone series is a new emergency dialer.

With an emergency dialer, you will be able to quickly access local contact information for police, fire, and medical services. This dialer is able to contact before mentioned services even when the phone is locked and when you are traveling.

The idea is to quickly access the default emergency number no matter in which country you are currently in, service will find the appropriate number and set it as default so if you need it there is no delay in searching for the appropriate number and dialing it.

Once the service is enabled on the device you can swipe up and tap Emergency call without unlocking your phone or you can press and hold the power button for five seconds and tap Emergency.

If you have a Pixel smartphone go to the Google support page and follow instructions on how to enable this service. It costs nothing and it could potentially even save your life.

If your IP address expires, you will most likely experience interruptions when browsing the web. In such cases, you have to release and renew the IP address by executing the following commands:

• ipconfig /release
• ipconfig /renew

So if you are trying to renew the IP address of your Windows 10 computer using the commands given above but you encounter an error message instead that says, “Unable to contact your DHCP Server”, then you’ve come to the right place as this post will guide you in fixing this error.

Recently, some users reported not being able to boot up their Windows 10 computers. And during the startup phase, at some time, the bootup sequence is halted with a Recovery error along with an error message saying, “Your PC/Device needs to be repaired” with an error code of 0x0000605. This kind of error message indicates that Windows was not able to verify the digital signature for the file as the signing certificate or it could be that it has expired. To resolve this error, you can follow the potential fixes given below and see if you stumble upon a fix that might work out for you.

Option 1 – Change the Date & Time settings in the BIOS

Some users reported that they were able to fix the error by changing the Date & Time settings in the BIOS. Upon checking, they saw that in their BIOS settings, the date was off several years. As a result, the incorrect date and time settings end up ticking the system into believing that the Windows build has expired long before the actual expiration date. You can check if the error pops up due to the same reasons by accessing the BIOS settings. To do so, you have to tap the Boot key that’s associated with your motherboard manufacturer during the initial startup phase. After that, you can search for a particular boot key online or you can also tap keys like F2, F4, F8, F10, F12, and the Delete key. Once you’re able to access the BIOS settings, locate the Date & time or anything similar, and then check if the date is correct or not. If not, you need to change the date to the actual date and then save the changes made and restart your computer and then check if the issue is now fixed or not. Just remember that if the actual date is past the expiration date of the build you have, you need to change it to an older date. If your Windows 10 PC is able to boot back up, you have to update it to a stable Windows build and then go back to the BIOS settings and change the date to the current one else you will definitely encounter Windows update errors in the future as well as security alerts.

Option 2 – Perform a clean install of a stable Windows 10 build

If every system boot fails accompanied by a BSOD error with error code 0x0000605 “A component of the operating system has expired” and you’ve already followed every instruction on option 1, then it’s most likely that your current Windows build has already expired. Remember that almost all the Windows 10 Insider Preview builds (98xx) are created along with an expiration date and when your computer reaches the expiration date, you won’t be able to boot your computer up. Note that the exact expiration date varies based on the build number. And prior to the expiration date, the operating system will start to display some error warnings telling you that the build will expire and urge you to update the most recent build available. And so once the computer reaches its expiration date, it will begin to reboot every three hours until it no longer boots up which is about 2 weeks approximately after the license has expired. Once the expiration date is up and your computer no longer boots up, you need to perform a clean install and then install the latest Windows 10 build to resolve the issue once and for all.
