How to Fix Error 1321 on Your PC

Same as in previous Windows versions, Windows 11 will also use certain applications as default ones for opening certain file types and file extensions. And yes, same as in previous versions it will come preconfigured for certain file types and associated applications like for example photos for pictures. Of course, users usually have their own favorite applications for certain file types and much more prefer to open them inside the application of their choice instead of the default one. We can change the default application like in previous Windows versions but this time there are two ways and overall more control of this process. Windows 11 has settings for choosing default file type applications and default file extension applications giving you more control of this process.

The opening setting for apps

Whatever you wish to change default application or default extension application you will need to open settings for default application. Follow steps to quickly go into it.

1. Press ⊞ WINDOWS + I to open settings
2. Select Apps on left
3. On the right part select Default Apps

Now you are in settings for choosing default applications

Choosing default application by file type extension

This is considering by Microsoft as a typical way to set default applications inside Windows 11. Once you are inside the settings app there is a box labeled Enter a file type or link type. Inside the search box, type in file extension that you wish to associate the application with like .JPG, .TXT, or other. If the file extension is not associated with any application you will be presented with a Choose a Default button, if however, the file extension is already associated with the app, you will need to click on the app box itself. In any case, a pop-up will appear and ask How do you want to open YOUR FILE EXTENSION files from now on? Choose Application from the list of presented ones and click on OK.

Choosing default file type

Another method is to select the default application by file type selecting application for it. In the settings screen, under the search box, you will have a list of installed applications. Choose the application that you would like to associate a file type with and click on it. On the next details screen scroll down and select the file type that you want to associate with the selected application and click on OK.

Other/third method

There is also the third method for choosing the default application for file type but it includes some surfing on your hard drive and it can be more time-consuming for first-time settings. But it is fairly quick when you need to only use it once on some new file type (for example you have a new application installed and want to switch just one file type extension to that application). Locate the file that you want to associate with the application and right-click on it. Select Open With from the menu and then Choose Another App. Pop up will appear, select the application that you would like to use, and check the box beside Always use this app to open CHOOSEN EXTENSION files followed by clicking on the OK button.

A runtime error is commonly an error that's created after the PC is operating software and encounters a problem of some form. For instance, a runtime error like run-time error code 7 reveals an "out of memory" dilemma.

Solution

Error Cause

Run-time errors are normally brought on by clashes with TSR (Terminate and Stay Resident) applications or additional operating applications, software problems, storage problems, or pc viruses.

Troubleshooting a Run-time Error

First, enter the run-time error signal into a search engine to see what info you will get about the precise runtime issue you are receiving. Next, end - job all running applications and TSRs to make sure these aren't the origin of the issue. You can certainly do so by obtaining the job manager by striking Control Alt Delete.

In case your issue is regularly occurring with a unique program, go to that system programmer's site and obtain any upgrades and patches. If unavailable, try uninstalling the application involved and reinstalling it.

In the event the issue is occurring with the os, you may consider reinstalling it although it is a huge commitment. A much better idea would be to try a fix for both Windows XP or Windows 2,000. It is possible to fix and scan files by typing : sfc / scannow, heading to the Begin switch, Run, and then pushing enter. Make certain to put an area between sfc and the reduce.

You might have an equipment or storage dilemma if these measures have not resolved your run-time errors. If that is the situation, contact the support of the application under consideration for potential support accompanied by the pc or motherboard manufacturer.

Many run-time problems can be solved by upgrading the application that's creating the problem. This is only because the programmer's frequently releasing patches and improvements for their applications as insects are found and repaired.

Storage problems may frequently be fixed by rebooting the pc. Consider a reboot a short-term repair. Rebooting clears the memory but in case your COMPUTER does not have adequate memory for your applications you're operating, or sufficient hard-drive space you'll immediately run out of memory again. Something less than this sum may cause memory issues since the computer's swap file isn't in a position to expand in dimension as required.

To assess the quantity of free area, available My Computer and right-click on the HDD, generally the D: drive. Select Attributes in the menu and see the disc's ability. Perform the disk clean-up function by following prompts and pressing the Disk Clean-up button, if the room is reduced.

You may be getting run-time errors, in case your storage chip is really failing. Eliminating and changing the awful memory chip will solve the difficulty. If you're encountering other runtime-related errors, like an install runtime issue, try cleaning away the portions of the registry with some software solution. 

Upgrading your computer from Windows 7 or Windows 8 to Windows 10 or even upgrading Windows 10 to a new version is not that simple. The setup initially checks for all the drivers and other software utilities installed on your computer and verifies and blockages or upgrade or upgrade blocks with respect to any of those drivers or any of those software utilities regardless if you use the Windows 10 ISO or the Windows 10 Upgrade Assistant. One of these common errors, when you upgrade or update your computer, is the “The Display is not compatible with Windows 10” error. This kind of Windows Upgrade error is related to the compatibility of the Graphics Driver installed in your computer. But worry not for this post will guide you in fixing this problem. The “The display is not compatible with Windows 10” error has the same workarounds as the following errors:

• These devices aren’t fully compatible with Windows 10.
• The display is not compatible with Windows 10. Check with the manufacturer for support.
• The display manufacturer hasn’t made your display compatible with Windows 10. Check with the manufacturer for support.

To resolve this Windows Upgrade error, here are some suggestions that could help:

Option 1 – Check for incompatible drivers in your computer

• Open the Device Manager from the WinX Menu.
• Then expand the list for Display Adapters.
• Next, right-click on the NVIDIA Graphics Card list and select Enable.
• After that, right-click on it again and click on the “Update Driver Software…” option.
• After doing so, a new window will appear and from there, click on the “Search automatically for updated driver software” option.
• Then check if Windows is now able to detect your Graphics Card as well as the latest driver for it. If not, proceed to the next step.
• Right-click on the driver again and click on the “Update Driver Software…” option.
• Now click on the Browse my computer for driver software option and then click on Let me pick from a list of device drivers on my computer.
• Afterward, select a compatible driver for your computer named NVIDIA Graphics Card and then proceed.
• Wait for the whole process to be completed and restart your computer to successfully apply the changes made.

Option 2 – Get the latest version of Graphics drivers from the manufacturer’s website

In case you don’t know the manufacturer of the Graphics Processing Unit or GPU of your computer, you need to check first. They’re usually NVIDIA, Intel, or AMD. So if your computer’s Graphics Processing Unit is manufactured by NVIDIA, you need to get the latest version from their official website.

Option 3 – Try to install the latest Graphics driver in Compatibility Mode

If you’re not able to install the Graphics drivers you’ve downloaded, you can try installing them again but this time using Compatibility mode. Follow the steps below to do so:

• You need to download the driver and place it on your desktop.
• After that, right-click on it and select Properties.
• Next, switch to the Compatibility tab where you should see two options:
  • Compatibility troubleshooter, and let Windows figure out what works best for you. If it fails, follow the next.
  • Manually choose the version of Windows it was correctly working.
• You also have the option to change the DPI settings and see if that helps. Then click the Apply and OK buttons.
• Now right-click on the file and select the “Run as administrator” option to install. After that, you should now be able to change your screen aspect ratio to what you were using early on.

Note: If you have other programs that won’t work on the existing version of Windows, then make sure to run the program in a Compatibility mode.

Option 4 – Try to run the Program Compatibility Troubleshooter

You might also want to run the Program Compatibility Troubleshooter. This built-in troubleshooter is available in the Windows Update & Security section. From there, select Troubleshoot. This will find a list of programs for you and since you have already downloaded the driver files, just click on Not Listed located at the top of the program list. After that, browse and select the driver files and then let the program do its job.

So, you have finished with work, game, movie, music, email, or whatever on your PC, you look at the clock, it is late, you decide to go to sleep or outside, you click on the power button and choose shutdown. Now when a PC is shut down you feel good and go with your business but the next time you power it up you get the same error like the computer never really shut down in the first place. You wonder why and reboot it, just in case and all of the sudden error is gone.

If something similar has happened to you or you had the feeling that after shutting down your computer has not really felt like shutting it down, do not seek professional help, everything is OK with you because when you click on shut down, your computer does not really shut down!

Truth is that Microsoft has changed how to shut down works and how rebooting works in Windows with an update but has not publicly said anything about it so some users may experience this feeling of not shutdown phenomenon and might even think there is something wrong with their PC.

Why this change?

A few years ago shutdown button and option in Windows were really shutting down OS, but things changed when Microsoft wanted to increase boot-up speed. Now when that decision was made shutdown option was changed. So, what was changed? Well in order to increase Windows booting time, the shutdown will now turn off power to PC components and it will look like everything is indeed shutdown but the Windows kernel will actually be saved to a hard drive with all settings and just awaken once the PC is turned back ON. This will result in all errors and other stuff being just still present same as they were once the system was instructed to be turned off.

Rebooting your PC will now clear kernel and file from the hard drive and you will get a clean system startup without any issues tied with the kernel itself.

Workaround

Now that we know why and what change has been made to Windows logical question is can we shut down our PC at all properly? Luckily for us, the answer is yes and we will not need any external application to do it, we can still do it inside Windows itself and it is quite quick and easy.

Bringing back the old shutdown

In order to bring the old shutdown functionality of your PC please follow the instructions but be aware that by doing this your PC will boot a little bit slower since it will have to load the kernel from scratch each time computer is turned ON.

First thing is to go to settings and go to System

Then once you are inside the system, navigate to the power and sleep and click on it to select it. Once you have it selected to all the way to the right and click on additional power settings.

When you click on advanced power settings you should be led to the control panel's power options. Inside this panel click on top left link where it says Choose what the power button does.

Inside options, you will need to untick the box next to Turn on fast startup (recommended), this option has been ticked ON by the Windows update and probably without notifying you. Option means exactly what was described, it will save kernel state on the hard drive for faster boot time but sadly it can cause some issues since it will never be reloaded from 0.

If you are unable to uncheck the box click on the text beside the shield icon that says: Change settings that are currently unavailable (you will have to be logged in as administrator).

Conclusion

Altho turning off fast startup and shutting down the PC completely will for sure extend your bootup time I still believe that it is the right choice since sometimes a lot of clutter and bad things accumulate over time inside the OS and can cause a vast variety of problems in a long run. So stay safe and shut down that PC as it used to be in the past.

Hello everyone and welcome to another great tutorial from errortools.com I hope everyone is feeling great and that you are prepared to boost the performance of your computer. This time we will speed up Windows startup time and overall performance by eliminating startup programs that we don't need and do not use. Microsoft itself and some application developers tend to have some applications or some services always active and set to be loaded on Windows startup. If you want to change which of these applications are starting up with your Windows and change them, follow this easy guide and you will be speeding up your Windows in no time. First thing is to open a task manager, fastest and most direct way of doing this is with a keyboard combination of CTRL + SHIFT + ESC When Task Manager opens, click on the startup tab on top. Once you click on startup you will get a list of applications that are set to be started when Windows is booted. You can now click on the application and then click on disable on the bottom button, the application status will update in task manager to disabled and it will not be booted anymore when Windows starts. In this same manner, you can enable back some applications if you changed your mind about them. Please note that some applications are using some services and must have them running or they will not work properly. The best practice is to disable applications you are positive you will not use or use rarely so you do not want them to slow down Windows.
