How to open UWP apps from the command line on Windows 10

UWP apps are different from desktop apps in many, many ways. One stark difference between the two is that a UWP app doesn’t have an EXE. If you want to open a UWP app, you can go through the Start Menu, the apps list in the Start menu, you can create a desktop shortcut for them, or add them to the start up folder. If you want to open UWP apps from the command line on Windows, you can. The process is a bit complicated but it’s possible.

Find PackageName

Tap the Win+R keyboard shortcut and enter the following. Tap Enter.

shell:AppsFolder

In the folder that opens, you will see all UWP apps that are installed on your system. Look for the app that you want to open from the command line. Right-click it and select the create shortcut option from the context menu. The shortcut will be placed on the desktop.

Go to the desktop, right-click the shortcut, and select Properties from the context menu. On the Shortcut tab, note down what’s in the Target field. This is the package name and you will need it in the next step.

Package list

Open PowerShell with normal user rights. Run the following command. You can change the name of the text file to whatever you prefer.

get-appxpackage > UWP_Apps_List.txt

This will create a txt file in your user folder’s location. Go to the following location and it will be there. Open this file and then move to the next step.

C:\Users\YourUserName

Find FamilyPackageName & Install location

Open the text file and use the find box to look for the PackageName you found in the first step. Once you find it, you need to look for two lines and copy the information there for use in the next step.

The first bit is the “InstallLocation” line. Copy the location the app is installed to.

The second bit is the “PackageFamilyName” line. Copy it as well.

Find Application ID

Open File Explorer and in the location bar, paste the install location of the app that you copied in the previous section. Tap Enter. In the folder that opens, you will find a file called AppxManifest.xml. Open it with Notepad.

Use the find feature again and look for the following;

Application ID

Note down the ID.

Run app command

Now that you have all the information you need, it’s time to write the command to run the app.

Syntax

explorer.exe shell:appsFolder\PackageFamilyName!Application ID

Example

explorer.exe shell:appsFolder\4DF9E0F8.Netflix_mcm4njqhnhss8!Netflix.App

You can paste the above command in Command Prompt or in the run box and it will open the app in question. You can also use it in scripts.

How to merge multiple audio files into one on Windows 10

Editing audio or video files is never easy. The apps built for these editing tasks take time to learn and often you have to be mindful to pick apps that won’t downgrade the quality of your original file(s). If you need to split an audio file, you’ll find plenty of free, and simple apps are up to the job. If you’re looking to merge multiple audio files into one, the same apps may not be up to the job. Audacity can do both.

Merge multiple audio files

Open Audacity and drag and drop the audio files on to the app. Multiple files are added one on top of the other and visually, you can tell between the various tracks. The tracks can be played one-by-one, or both at the same time.

To merge the files, double-click one audio file to select it, use the Ctrl+C keyboard shortcut. Click at the end of the other audio file, or anyone in the middle, and tap the Ctrl+V keyboard shortcut to paste it. The files have been merged. You can now delete the second file and use the export option under File on the menu bar to export your merged file.

If you want to edit the file, you can do so before you export it or you can edit the merged file you export. In both cases, the result will be the same though, depending on how comfortable you are with Audacity, you might find that editing a single merged file is easier.

Merging doesn’t have to be linear i.e., you don’t have to add one file to the end or start of another. You can add a file in the middle of another. All you have to do is click where you want to add the file.

Limitations

Merging multiple audio files comes with a few things you have to consider. The first thing you need to consider is the file format. Since we’re using Audacity, it supports AIFF, AU, FLAC, MP2, MP3, OGG, Vorbis and WAV. It supports M4A (AAC) and MOV on macOS and you can add M4A support on Windows 10 by installing ffmpeg libraries. Make sure the media files you’re merging are supported by the app.

Secondly, if the files were made in different recording environments, merging them will not make the sound uniform. You can manipulate the audio as one, or in portions. It’s up to you but you cannot expect the entire audio to sound the same unless it was recorded in the exact same environment or in a single setting.

How to extract a single page from PDF files

Creating PDFs isn’t the easiest job. The format may be easy to view but creating files in it is often complicated. Having to install additional apps to make simple edits is an unnecessary part of dealing with these files. If you need to extract a single page from a PDF, you can install a free PDF editor, or you can use your browser.

Most browsers will let you print a web page or any other file they can open to a PDF. Chrome definitely has this feature and you can use it to extract a single page from a PDF.

Extract a single page from PDF files

Open the PDF that you want to extract a page from in Chrome. Click the print icon in the bar at the top. In the Print dialog box, you can choose how the document is printed. One of the options that you can customize is which page is printed. Open the range of pages dropdown and select ‘Custom’. Enter the number for the page that you want to extract.

After you select the page you want to extract, open the printer selection dropdown and select the ‘Save as PDF’ option. Click Print, and select where you want to save the file. You can give it a different name if you want to.

When you open the file, it will have just the one page that you selected in the print dialog box.

This same option will work on most modern browsers. Both Firefox and Edge have it. You will need to dig around in the controls a bit or you can always tap the Ctrl+P keyboard shortcut to bring up the print dialog.

Most operating systems have some sort of app that can open PDFs and you can use that app as well to the same end. On Windows 10, you have Edge and on macOS, you have the Preview app. Both make use of the print dialog/settings that they support and the option to selectively print a single page is basic to the print dialog.

This same trick can be used to extract a series of pages from a PDF e.g., you can extract pages 10-20 by entering it in the Pages option. You can also extract select pages that are not in range by separating them with a comma. For example, you can enter 6,12,24 in the pages option to extract those three pages into one PDF file.

How to change virtual memory size on Windows 10

Virtual memory is essential on Windows 10. By default, the OS will manage the virtual memory on its own. It will set a value based on what it thinks is best and how much RAM you have. You can however, change virtual memory size on Windows 10 to whatever you like. You can decrease or increase it. You should know that increasing it requires that you have that much free space on your disk. Here’s how you can change virtual memory size on Windows 10.

Change virtual memory size

Open the Control Panel and go to System and Security>System. In the column on the left, click Advanced System Settings.

On the System Properties window (window 1 in the screenshot below), go to the Advanced tab. Click ‘Settings’ under the ‘Performance’ section. This will open the Performance options window (window 2 in the screenshot below). Go to the Advanced tab, and click ‘Change’ under the ‘Virtual Memory’ section. The Virtual Memory window will open (window 3 in the screenshot below). Uncheck the ‘Automatically manage paging file size for all devices’ option. You can allocate virtual memory for each drive.

Make sure the C drive is selected and select the ‘Custom size’ option. You can now enter how much space the virtual memory should take up. There is a minimum limit which is 16MB and that’s really, really small. There’s also a recommended size which is quite small and then there’s the current size of the virtual drive.

Keep the above limits in mind and then change the size of the virtual memory. When you’re done, click OK/Apply to close all three windows. You will see a prompt telling you that a system restart is necessary in order to apply the change. Accept the prompt, and restart your system to change virtual memory size.

Increasing the virtual memory size will make your system run smoother but within reason. If you have trouble running apps that are RAM heavy, increasing the virtual memory should be able to help if not solve the problem. Decreasing its size may have a negative impact on your system’s performance. In fact, setting it to the recommended size might not be a good idea. The recommended size is considerably less than what Windows 10 sets by default but that doesn’t mean you should actually listen to the recommendation.

If you have the space to spare, adding a little extra GBs to the virtual memory isn’t a bad idea. It’s easy to change back if it doesn’t deliver any improved performance so there’s no harm done.

How to make a picture-in-picture video on Windows 10

Video editing can be both simple and complex. It all depends on the kind of footage you have to work with. The more complex a video edit is, the more advanced and feature rich an app you’ll need to edit it. That said, if you want to make a picture-in-picture video, you’ll find that most solutions require a paid app. There are some feature rich video editors out there that are free and can create a picture in picture video but they’er a bit complicated to use. We recommend going with Davinci. It doesn’t exactly offer a super intuitive interface so we’ll walk you through the process.

Download and install Davinci.

Need to crop videos? Try Handbrake.

Picture-in-picture video

Open Davinci and create a new project. Drag and drop the video files you want to use in the video on to Davinci.

You should know which video is going to be the main video, and which will appear as a small thumbnail with-in that video. Drag & drop the main video on to the area/timeline under the preview frames. Repeat this for the second video. The trick is to add the thumbnail video second. Much like layers, the second video is on ‘top’ of the first one and will be visible over it.

Select the smaller video and at the top right, click the Inspector button. Look under the Transform section in the Inspector. There are two tools you will use to set this video as a picture-in-picture thumbnail.

The first is the Zoom. Since you want the video to be smaller, you will reduce it to less than one. Drag your mouse over it to reduce its value. You can watch the size of the video decrease and as it does, the main video behind it will be revealed. By default, this smaller video will be in the middle. You now need to change where it is positioned over the main video.

Go to the Position tool and drag you mouse over the X and Y fields to move the video.

Once you’re done, it is time to export the video. Look at the very bottom of the timeline, and select ‘Deliver’.

At the top left, select what format you want to export the video to, and when you’re done, click the ‘Add to render queue’ button.

At the far right of the preview window, click Start Render and your video will be exported. It will take time depending on the size of it.

Davinci isn’t a simple app to use but for small things like this, a few simple directions will help you get the job done.
