The Photos app in Windows 10 is the default photo viewer. However, there are times when it might encounter some problems while you use it. One of these problems in the Photos app reported recently is where users try to export or share the images and videos from the app but weren’t successful in doing so. This can be really quite a hassle in opening images on your computer, especially since the Photos app is the default photo viewer in Windows 10 and if you don’t have any other photo viewer app installed. This kind of problem in the Photos app can be noticed when you try to use the “Remix” function for both photos and videos. In other words, this problem can occur with just pictures, videos, as well as a combination of both. So if you are trying to watch a video using this app, then you wouldn’t be able to play it. In such a case, the only thing you can hear is the audio but you wouldn’t see anything except for a hazy purple screen that has not export or share option. There are several possible causes for this problem and it could be fixed by updating the display driver/graphics driver or disabling the hardware-accelerated video encoding. You could also try updating or resetting or reinstalling the Photos app. For more details, follow each one of the suggestions provided below.

Option 1 – Try to update the Graphics driver

You can try to update your Graphics card driver using the Device Manager in your computer to resolve the blank dialog boxes problem or you can also go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it. To update your Graphics driver via Device Manager, refer to these steps:

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in 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. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Option 2 – Try disabling the hardware-accelerated video encoding

The next thing you can do to fix the problem is to disable the hardware-accelerated video encoding in your computer. To do that, follow these steps:

• Open the Photos app and click on the visible three dots located in the upper right corner of the app and then select Settings.
• From there, you should see the version number of the app in the “About this app” section. So if your app is version 2018.18071.****0.0 or greater, you should see the Video section which has a toggle button.
• Turn that toggle button off to disable hardware-accelerated video encoding in the Photos app. This should fix the problem, if not, simply follow the next given options below.

Option 3 – Try to update the Microsoft Photos app

• Open the Microsoft Store and click on the three horizontal dots for the menu located on the top right portion of the window to see the options.
• Next, select Downloads and updates and then click the Get updates button in the top right. This will install any pending updates for all the apps including the Microsoft Photos app using the Microsoft Store.

Option 4 – Try resetting the Photos app

• To get started in resetting the Photos app, open the Windows 10 Settings.
• Then go to Apps > Apps & features.
• After that, scroll down until you see the Photos app option – click on it and open its Advanced options.
• From there, you will see the Reset button, click on it and click and then click on it once more to confirm.

Note: The process may take a couple of minutes to complete. Once it’s done, open the pictures again using the Photos app.

Option 5 – Try reinstalling the Photos app

If none of the options given above worked, then you might want to consider reinstalling the Photos app. Unlike what most users think, it isn’t really that hard reinstalling preinstalled apps as you have the Windows PowerShell for that. To use this program in reinstalling the Photos app, follow these steps:

• Open the Windows PowerShell program with admin privileges and key in the following command:

Set-ExecutionPolicy Unrestricted

• After that, execute this second command to re-register and reinstall the Microsoft Photos app.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}

Note: In the command given, do not forget to replace the “PackageFullName” with the actual package name for the Photos app. After executing the command, it will uninstall the Photos app from your computer so you need to install it again from the Windows Store by simply looking for it. Once you found it, just click on install to start the installation process.

Caching is used to enhance the performance of applications in Windows and other operating systems. It helps applications to load faster but there are times when the cache can get damaged or corrupted and as a result, you might encounter some issues. One of them is in the Firefox browser where the “Your Firefox profile cannot be loaded, It may be missing or inaccessible” error message may appear. You could also encounter this kind of error when Firefox is unable to access or find the profile folder. In case you don’t know what the profile folder is, it is where Firefox stores your user data and settings by default. Firefox pulls information from this folder each time you choose to open it. You can find this default Firefox profile folder under the %APPDATA%MozillaFirefoxProfiles folder. If you experience issues when trying to access the Profile Manager, you have the option to create a new default Firefox profile folder. This will fix the “Your Firefox profile cannot be loaded, It may be missing or inaccessible” error. How? Simply follow the given steps below. Step 1: Tap the Win key or click the Windows Start button to open the Start menu. Step 2: Next, type “%appdata%” in the field and hit Enter to open the hidden AppDataRoaming folder. Step 3: Now double click the Mozilla folder as well as the Firefox folder. Step 4: From there, look for the “profiles.ini” file and delete it. Make sure that you don’t delete the Profiles folder which should have the icon of a file folder. Note: Keep in mind that the .ini file extension is identified as the file that features a gear icon beside the “Configuration settings” or “Application settings”. Step 5: Once you open Firefox, a new profile will be created. On the other hand, if you know where your profile exists, you can try the following steps below to help Firefox locate it.

• First, you need to move the profile folder back to its original location.
• Next, restore the profile folder’s original name if you have modified it.
• Then create a new profile using the Profile Manager and give it an appropriate name.

The Control Panel is one of the most important tools in Windows which allows users to control and change various settings. However, there are cases when it experiences some problems like when users aren’t able to open it. Recently, a lot of users complained about not being able to open the Control Panel. To be more specific, users were able to open it but only lasted for a second, and then it’s gone. This is not just some issue you can ignore as this will prevent you from accessing some major settings in your computer and you won’t be able to perform some important task without it. According to security experts, this issue is most likely caused by a bug in the Windows Update. If you have installed an update recently, then it’s most likely the culprit. Aside from the Windows Update, there are also other things that can cause this issue. Some of them are the IDT audio panel and a control panel file that causes conflicting issues with the control panel that leads to this problem. Aside from these aforementioned cases, the Windows Error reporting services could also be one of the causes of this issue. As you can see, since there are a lot of possible causes for this problem, this post prepared a lot of options as well which you have to check out. Follow each one of them and see which one worked best for you.

Option 1 – Try updating your Windows 10 PC

If you haven’t updated your PC to the latest version of Windows 10, then you should. A lot of users found that the issue with the Control Panel was fixed right after they updated their Windows 10 PCs. This is probably because Microsoft has probably released a fix on one of the latest updates.

Option 2 – Try uninstalling the IDT Audio Panel

For some users, uninstalling the IDT Audio Panel from their PCs did the trick. You can also try doing the same thing to fix the vanishing Control Panel. According to these users. The IDT audio panel was the one that’s causing the issue. To uninstall the IDT audio panel, here’s what you have to do:

• Tap the Win + R keys at the same time to open the Run dialog box.
• Then type in “appwiz.cpl” in the field and tap Enter to open the “Uninstall or change a program” screen of the Control Panel.
• From there, look for the IDT audio panel, select it and then select the Uninstall option and follow the next on-screen instructions that appear.

Note: If you are unable to locate the IDT audio panel or you simply can’t access the Uninstall or change program screen or you can’t keep Control Panel open for a long time, here’s what you can do:

• Tap the Win + R keys at the same time once again to open the Run dialog box.
• And in the field, type in “devmgmt.msc” and hit Enter to open the Device Manager.
• After opening the Device Manager, look for the “Sound, video and game controllers” option and double-click on it.
• From there, locate the IDT audio panel or “IDT High Definition CODEC” and select Uninstall and follow the next instructions that appear.

Option 3 – Try deleting or renaming IDTNC64.cpl

IDTNC64.cpl is a control file in the control panel. However, it might be the one that’s causing the problem as it could be conflicting with the control panel. As a result, the control panel crashes after a second or more. Many users have fixed the problem by either renaming or deleting this file – the safer option would be is renaming it.

• Tap the Win + E keys to open File Explorer.
• In the address bar located at the top, type in “C:\Windows\System32” and tap Enter to open this folder.
• From there, look for the IDTNC64.cpl file, right-click on it and select the Rename option.
• You can name the file anything you want but it’s better if you rename it to “oldcpl”.
• After you rename the file, try opening the Control Panel again. It should work fine now.

Option 4 – Try to disable the Windows Error Reporting Service

As mentioned earlier, the Windows Error Reporting Service is also known to cause the issue so some users disable it and got the issue fixed.

• Tap the Win + R keys.
• In the field, type in “MSConfig” and hit Enter to open System Configuration.
• After opening System Configuration, go to the Services tab and look for the Windows Error Reporting Service and uncheck its checkbox.
• Click the Apply button and click OK. You should now see a date in the Disable Date column. Then check if the Control Panel is now working properly if not, restart your computer and check once more. That should fix the problem.

Option 5 – Try opening Control Panel via Run

This option is more of a workaround than a solution as it does not really fix the issue with the Control Panel but rather helps you in accessing the controls at the very least.

• Tap the Win + R keys to open Run.
• Type in “appwiz.cpl” in the field and tap Enter to open the Uninstall or change program screen of the Control Panel.
• Next, copy and paste “Control panel all control panel items” on the address bar located at the top-mid part of your screen. You must not type the given address and simply copy and paste it. After that, you will see a list of control panel controls you can use.

This guide is made in a way to takes into account that the application itself is completely installed on your Windows 10 machine if you can not even install the application you will need to search solution for that particular application since that can not really be generalized and pinpointed issue, every application is different.

Running old applications using the compatibility option

All of that being said, let's start that old app you have. First thing is to locate an executable file or shortcut of the desired application. Once it is located, right-click on it to bring up the menu, and all the way to the bottom you will find properties. Left-click on properties. The application settings screen will open, in upper tabs locate Compatibility and left-click on it. After the click, you will find yourself in application compatibility settings. In this window, you will face different options to run the chosen application in various modes in order to make it run. How settings are self-explanatory and different applications will need different settings sadly we can not cover them all but your safest bet is to run them in an environment where they have worked. For example, if the application was working fine in Windows XP and required administrator privileges, check Run this program as an administrator and Run this program in compatibility mode for Windows XP.
