Calculator is not working in Windows

Device drivers serve as a connection between the hardware in your computer and the operating system. So if any of the device drivers fail, the concerned hardware will stop communicating with Windows. And when you encounter some network-related issues, you can run the Network Adapter troubleshooter to fix them. However, this built-in troubleshooter does not work all the time as there are still problems that it can’t fix on its own and you’ll see the following error message:

“Windows could not find a driver for your network adapter.”

If you encounter this kind of error, read on as this post will help you in fixing the problem but before you get started in troubleshooting the problem, try running the Network Adapter Troubleshooter again.

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Refer to each one of the solutions given below to get started:

This is the first thing to check if the issue is due to software or driver malfunctioning, there is a shortcut for rebooting graphic driver inside Windows 11. Press WINDOWS + CTRL + SHIFT + B to reboot the graphic driver and see if this fixes the issue. A beep sound should be heard during this process and the screen should turn back to normal.

Check connections

Sometimes the screen can go black due to a faulty connection or cable. If you have it at your hand try a different cable or slightly and gently nudge the existing one to see will screen flicker. If you are on a laptop try gently moving the lid from back to front and pay attention to the screen. If screen flickers or picture returns with this method, cable or connector needs to be replaced.

Clean your computer

The black screen can be because the computer is overheating. If this is the case either fan inside is not working properly or there is a lot of dirt and dust that needs to be removed so airflow can be established again for proper cooling. We have an article on errortools.com on how to properly clean your PC but if you are not technical enough maybe the best solution would be to call someone who is or to take the PC to service for cleaning.

Change The Projection Settings

Press WINDOWS + P to open projection settings, check to see if PC is set to PC screen only. If any other option is selected change it to PC screen only since this can cause random black screen issues.

Scan system for malware

The black screen can also be caused by various viruses and malware. IF you have anti-virus software, run a full system scan to check it for malware. If you do not have one, download a free one and run a system scan, we recommend Bitdefender.

As you know, one of the basic apps in the Windows 10 operating system is the calculator and it can even be extended to a scientific calculator which makes it really useful for users. However, there are instances when you might encounter some issues while using this app. One of the issues about the Calculator app that’s been reported recently is that the Calculator app is not working. If you encounter 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 problem. Based on the reports, users claimed that the issue with the Calculator app occurred right after they’ve installed a feature update, while other users claimed that the Calculator app never really worked on their computers and there are also cases where the app opens but it either freezes or crashes. According to researchers, the main causes of the problem include a feature update that could’ve altered the settings. It could also be due to problems with the login account or corrupted and missing files, or the problem could also with the calculate app itself. To resolve this problem, here are some suggestions you can follow.

Option 1 – Run the System File Checker Scan

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 to good system files that might be the reason why the calculator app is not working properly. 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.

• Reboot your computer.

Option 2 – Run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” that could help in fixing the Calculator app.

• 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
  • Dism (.)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 3 – Try logging into your computer using a different User Account

You might want to try logging into a different User Account since it is possible that the issue could have something to do with your log-in account. Thus, you can isolate this possibility by logging into a different user account. If you don’t have any other user account, simply create a new one by clicking on the Start icon and then go to Settings > Account > Family & other users. From there, go to the Other user's section and click on the Add someone else to this PC option, and then inputs all the needed information and restarts your computer. Once your computer has restarted, log into your computer using the newly created user account.

Computer voice control has moved a long way from its beginning routes and in today's age controlling your PC with voice is truly a reality and fully possible. Voice control is taking up the steam in everyday life, from simple commands in cars, Alexa, smartphones, TVs, etc. to modern computers.

Windows 10 has introduced voice control into PC with Cortana even during the installation process but a lot has changed from having a virtual assistant in begging days and in today's modern Windows 11 OS. You can now freely open apps, move, copy delete files, and even dictate in order to create a word document.

However, in order to take this advantage, you will need to turn it off first since it is disabled by default. Of course, you will need a microphone and some spare time to train Windows in understanding you properly.

Setting up Voice Control

Just like in Windows 10, in Windows 11 voice control is also in accessibility options and the first step is to turn ON Windows Speech Recognition.

Click on the Start button and type Settings into the search bar, click on Open, or press ENTER. On the left side of the settings, window locate and click on Accessibility. On the right part once Accessibility is selected scroll down and find a section titled Interaction and click on Speech. Turn on the switch next to Windows Speech Recognition.

A pop-up will appear that will lead you through the rest of the setup and that's it.

Improving Voice Control

In order to make your voice control better, if you are not satisfied with the results, you can sample more of your voice into the algorithm to tune it more to your liking. Sadly this option is still deep in Control Panel.

Click the Start button and type in Speech recognition into the search bar, look for the search result with Control Panel displayed under it, and click on Open. Click on Train Your Computer to Better Understand You and follow the instructions.

The process will probably take a few minutes. The more data you provide to the speech recognition model, the more accurate it will be when interpreting your instructions. You can train the model multiple times, and each time you do, it should improve the accuracy.

As you know, the Windows 10 Action Center has a stack of all the notifications that come from different applications on your computer. So each time an app displays notifications, it will be displayed for about 5 seconds and then it disappears right away. Although the allotted time for the notifications to be displayed is quite enough to catch your attention and help you get a glance at the message, there are times when you might miss it and you hoped it could’ve been displayed a lot longer. So in this post, you will be guided on how you can increase or decrease the display time of the notification in Windows 10. The best way you can view the missed notification is to click on the Action Center. From there, you will see all the notifications that are grouped by the applications. This means that if you have a lot of notifications, it would be hard for you to find what you are looking for. Thus, in such cases, the best way you can do is to increase the display time for which notification to stay on the screen.

To get started, refer to the instructions given below.

Step 1: Tap the Win + I keys to open Settings. Step 2: Next, navigate to Home > Ease of Access > Display. Step 3: After that, scroll down to the end until you see the dropdown to change the notifications where you should see the “Show notifications for”. Step 4: Then you can change the time from the default 5 seconds to 7, 15, 30, and so on. Step 5: Once done, the display time of the notifications should stay longer but keep in mind that you must choose the length wisely so if you have notifications from a lot of apps, then the screen will also be filled with multiple notification cards.

Microsoft Edge may be about to win a lot of fans by introducing a new feature that it says could prevent one of the most annoying things about being online. A new update to the browser suggests it is looking at a way to block auto-playing videos by default when a user navigates to a website. People spotted a new entry to the Microsoft Edge Canary browser where the company tries out its in-progress updates, that suggests auto-playing videos may have had their day at last. The new addition, for Mac, Windows, and Linux systems, is called “Autoplay Limit Default Setting”, with the description suggesting that Microsoft Edge would set the media autoplay setting to "Limit" as a default - stopping videos from starting up when a user lands on a website. Currently, Edge offers two options for users to control media autoplay - "Allow" (the current default setting), where all videos on a website will play automatically with sound, and "Limit", where media won’t be autoplayed on sites that a user has previously visited. It appears that Microsoft is looking to test the feature in Canary before rolling it out to a wider user base - as blocking autoplaying videos can cause issues for some websites. The same Canary entry also hints at a future "Block" option, which would presumably stop any videos or media from playing when a user lands on a website. However, this feature, which is also listed as being available for Mac, Windows, and Linux systems, doesn't appear to be enabled as yet.
