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.
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.
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:
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.
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.
If the first three given options didn’t work, you might want to reset or reinstall the Calculator app. To do that, follow these steps:
Note: You also have the option to reinstall the Calculator app. All you have the option to visit Microsoft Store and from there, uninstall the Calculator app.

New technology is bringing 76 billion transistors with 18,000 CUDA cores along with new gen ray tracing cores and improved Tensor cores as well. The new lineup also comes with DLSS 3 which is vastly improved from its previous version pushing a 4 times increase in frame rates over native rendering.

RTX 4090, a better model of GPU will come with 16,384 CUDA cores and a boost clock speed of 2.52 GHz. Also, it is packed with stunning 24 GB of GDDR6V VRAM. In Nvidia's words, its performance is twice faster than the 3090 Ti in games like Flight simulator, three times faster on Portal RTX, and four times faster on RacerX.
RTX 4080 comes in two modes, one with 12GB VRAM and a stronger one with 16GB VRAM but differences do not end here. The lower model is packing 7,680 CUDA cores while the stronger one is going to 9,728 CUDA cores. We will wait to see how will these cores count impact real-world performance in games.
As for prices, the flagship model RTX 4090 will be $1,600 USD and it will hit the market on October 12th. RTX 4080 12GB model will be $900 USD and the model with 16GB VRAM will go up to $1,200 USD. This, of course, is the price for Founders Edition cards, OEM cards from third parties like ASUS, MSI, Gigatech, etc will cost more.
