How to Open .key Files on Windows 10/11 [Step-by-Step] You can use iCloud to open keynotes files




It’s really easy to open a .key file, basically, a presentation created with Apple’s Keynote software


Nowadays, most presentation software can open KEY files so you should try Microsoft PowerPoint.

You can also use other similar tools to open the .key presentations like the ones listed below.

Another good option is to convert the KEY files to other file formats that you can open on your PC.



To fix Windows PC system issues, you will need a dedicated tool

Keynote is the presentation software included with Apple’s office suite. The application is Apple’s alternative to MS PowerPoint. However, Windows doesn’t support Keynote’s KEY file format.

Consequently, there is hardly any Windows software compatible with that format type. This doesn’t mean you can’t open Keynote presentations in Windows, but most users convert them to a compatible format.

How can I open KEY files on a PC? 1. Open Key files with PowerPoint or LibreOffice Impress

A great and easy way of opening KEY file presentations is to use good old Microsoft PowerPoint or the free LibreOffice Impress app. In fact, nowadays, any presentation software can be used to open KEY files.

Unfortunately, not all the programs will use all the features of the original KEY presentation. You may lose the formatting and if you had any transition effects they might be also lost.

However, any of these programs, including PowerPoint and Impress will allow you to open, start the presentation, or even save the KEY files.

You can save them but, of course, you won’t be able to do that in the original format. Microsoft PowerPoint will save the file as a PPT or PPTX format while LibreOffice Impress will offer the ODP and ODPX formats additionally.

After you edit the KEY presentation, all you need to do is to save the file by selecting the Save option in both apps and choose the format you want to use with the presentation.

These great tools are also great for converting the files before sending the presentations to someone who doesn’t have a Mac computer but as mentioned earlier, they will lose formatting and effects so edit them before sending.

Microsoft Powerpoint

Microsoft Powerpoint is the best presentation software on the market and it can also be used to open KEY files.

⇒ Get LibreOffice Impress

2. Open KEYs With File Viewer Lite

You can open the Keynote presentations with that software, but it doesn’t include any editing options. File Viewer Lite is also freeware that’s compatible with Windows platforms from XP up.

You can check out File Viewer Lite on this website page. Press the Download Now button there to save the software’s setup wizard, and then open its installer.

Expert tip:

File Viewer Lite supports drag and drop so that you can drag Keynote files from File Explorer (or the desktop) onto the software’s window to open them in FVL.

⇒ Get File Viewer Lite

3. Open Keynote files in iCloud

To open and edit a Keynote presentation with more Windows software, you’ll probably need to convert its format type. However, you can still edit KEY presentations in Windows with Apple’s iCloud.

ICloud is a range of cloud-based services that includes the Keynote, Pages, and Numbers web apps. As such, you can set up an iCloud account and open and edit a KEY file in a Windows browser.

This is how you can open a KEY file in the Keynote web app.

4. Convert KEYs to PPT or PDF Format

First, go to the Zamsar page to open ZAMZAR’s KEY to the PPT page.

Press the Choose Files button, and then select a KEY presentation to convert to PPT.

Select the PPT format type from the Convert files to the drop-down menu.

Enter an email address to send the PPT file.

Press the Convert button.

Open your ZAMZAR email, which will include a link to the PPT file. Then you can save the presentation to your hard drive.

Open the Zamzar page to convert KEY files to PDFs with ZAMZAR. Converting them to Portable Document Format is almost entirely the same, except that you select PDF from the Convert files to drop-down menu.

Thereafter, you can open the Keynote presentation in PowerPoint and Adobe Acrobat or other slideshow and PDF software.

Converting files to alternative formats is the usual way to open documents, presentations, and images that Windows doesn’t widely support. Of course, you’re not exactly opening a KEY file by changing its format.

However, converting presentation and text document files to alternative formats doesn’t usually have much impact on their formatting.

If you need to edit a Keynote file, PowerPoint’s PPT is probably the best format to convert it to as that’s more widely supported by Windows presentation applications.

PDF is one of the best universal file formats, but most PDF viewer software doesn’t include editing options. You can convert KEY files to both PPT and PDF formats with the ZAMZAR web tool as follows.

5. Convert the presentation to ZIP format

ZIP is a compressed archive format that you can convert KEYs to. You can preview the contents of a Keynote presentation by converting KEY files to ZIP format.

Here’s How To Open Nef Files In Windows 10

Here’s how to open NEF files in Windows 10




Using specialized software to open a NEF file will keep all the information stored inside.

Take a look at our picks below to find the best software that easily converts NEF to JPG Windows.

ViewNX2 is a great free option that also allows you to control hue, tone, and sharpness.

We’ve also selected Adobe Photoshop, Capture NX2, and other paid NEF file viewers for Windows.

One tool to open them all!

Popular file formats don’t need specific software anymore. Just download File Viewer Plus 4 and open them all in the same environment. Documents, media, archives, email, camera, infographics, source codes and many more – all are supported by this tool. Here’s what it does:

Opens over 300 file types

Edit, save and convert files

Batch file conversion

Nikon Electronic Format, a RAW file format containing digital photos taken by a Nikon camera. This format has detailed images as captured by the camera’s sensors, no compression or loss of quality.

The NEF file format stores metadata of the images such as the model of the camera itself, settings, lens information, and other details.

Stuff like the hue, tone, sharpness, or white balance is applied, but these are retained as instruction sets that come with the NEF file, and can be changed as many times as you want without affecting data.

With Nikon’s Capture NX2 software or other imaging programs, the after-capture processing of NEF files gives you greater control over the final image than when JPEG or TIFF files are processed.

You can then save them as TIFF, JPEG , or as NEF again. Provided that the original NEF file is preserved, the digital negative remains untouched and processing doesn’t change the original instruction set.

It is exclusive to Nikon cameras, and sometimes it is referred to as digital negatives and is written to the camera’s memory card in either uncompressed or lossless compressed format.

1. Use Adobe Photoshop

There’s no way you can talk about opening or editing image files without the name Adobe Photoshop popping into your mind.

This raster-based image editor can also be used as a NEF file opener. More so, the toolset allows you to take the NEF file and then turn it into a more manageable format, such as JPG or BMP.

Besides, NEF files could always use a little bit of doctoring themselves, and that is something that Adobe Photoshop can easily handle as well.

Normally, this world-class program is subscription-based to use, but now you can test it for a full 7 days without any type of limitations.

Note: If Photoshop cannot open the files, make sure you install the latest Camera RAW plugin supported by your version of Photoshop and try opening them again.

Convert any type of file, including NEF easily, without losing data by using Adobe Photoshop

2. Use FileViewer Plus

FileViewer Plus is an extremely powerful software and is highly rated on the market. It will open over 300 file formats including all the most popular photo formats.

The best thing so far about this tool is that it can be used not only on photo files. You can also open and edit video, image, and text formats without having to download other software.

⇒ Download FileViewer Plus now


GIMP, or GNU Image Manipulation Program, is a free photo editing software for Windows, though it requires some extra skills or time to understand and use it.

Although it’s not as simple as most free photo editors, if you want to open NEF files, then GIMP is one of the best tools to use for this task.

⇒ Download GIMP

4. IrfanView

Expert tip:

The software also has Photoshop filter support, Paint options, blurring, and more, all packed into an easy to understand and interactive interface.

Images saved in the Nikon Image Space can be browsed as if saved on your own PC. Once you login, you need not input your ID and password again, plus you can use the drag/drop for easy uploading of images.

⇒ Download ViewNX2

How do I process NEF files in my camera?

Here are the steps you can take to process the NEF files in your Nikon DSLR camera prior to opening the file:

In the Retouch menu, find NEF in-camera processing feature.

This lets you process NEF RAW files into JPGs within the camera, and is useful for shooting RAW files or sharing a quick JPG

Adjust Picture Controls or change images from color options like Black & White (B&W) or Sepia, change white balance, exposure compensation and so much more.

Once you’re done with and satisfied with the adjustments, preview it by pushing the magnifying glass button on the back of the camera.

Select EXE when you’re ready to save the JPG file to your media or memory card.

The original NEF file will be saved on the memory or media card so you can revert to the original capture when opening the NEF file on your computer.

If you have the right codec on your PC, you can open or view NEF files without the need for more software. For Windows 10, you don’t need to install the Microsoft Camera Codec Pack.

The codecs are built-in to the operating system, but should you want to add support for DNG formats, or others not supported, you would have to download a codec.

The Microsoft Camera Codec Pack enables viewing of a variety of device-specific file formats in Windows Live Photo Gallery and other software-based in Windows Imaging Codecs (WIC).

Installing it will allow supported RAW camera files to be opened or viewable in File Explorer and is available in 32-bit or 64-bit versions.

How do I convert a NEF file on Windows 10?

You can convert NEF files to different formats using a file converter or an image viewer/editor then save to a different format such as JPG, RAW, PNG, TIFF, PSD, GIF, and many others.

There are other online options that you can use to convert your NEF files to open in Windows 10 like Zamzar, chúng tôi and Online RAW converter that convert the NEF files to BMP, GIF, JPG, PDF, and TDG among others.

How To Create A Registry Key In Windows 11/10

The Windows Registry is a collection of settings that Windows and applications can use. It is a directory which stores settings and options for the operating system for Microsoft Windows. It contains information and settings for all the hardware, operating system software, most non-operating system software, users, preferences of the PC, etc.

The Registry consists of the following 5 Root Keys. Root Keys contain SubKeys. Subkeys may contain subkeys of their own too and contain at least one value, called its Default Value. A key with all its subkeys and values is called a Hive.

Each key has one of the Data Types – data types:






In this post, we will show you how to create a Registry Key in Windows 10.

Before you begin, it is always a good idea to either back up the Registry or create a System Restore Point.

The hierarchy of Windows Registry

To edit the Registry, we use the built-in Registry Editor or regedit. It displays a tree-like navigation structure.  The topmost is your computer, followed by a list of folders, and subfolders. These folders are called KEYS, and there are five fixed set of folders under the Computer.

HKEY_CLASSES_ROOT: Contains file extension association information which helps the computer understand what to do with a task when asked.

HKEY_CURRENT_USER: It contains configuration information for Windows and software for the current user.

HKEY_LOCAL_MACHINE: It stores the configuration for the software installed on the computer, and also for the Windows OS

HKEY_USERS: Here you can find a user-specific configuration for all users on that computer.


These are the master keys as you cannot create a NEW KEY under Computer – but you can generate new keys under any of these master keys.

How to create a Registry Key in Windows 11/10

1] Using Registry Editor

You also have the option to Rename, Export, Copy, and set Permissions.

2] Using the Command Line

You can also use Command Line to manipulate registry keys along with tips, features and safety methods.

3] Use Notepad to create REG files

4] Third-Party Tools

If you find the default registry editor complex, you can use tools like RegCool, Registrar Registry Manager Lite, and Registry Commander. They offer features like Undo, Redo, permission management, tabbed window, import, export, favorites and so on.

3] Use Programming

If you are an application developer, you should use programming to manage your application settings in the registry. Here is an example, and it will vary depending on the language you use to develop the application.

RegistryKey key = Registry.LocalMachine.CreateSubKey(@"SYSTEMCurrentControlSetserviceseventlogMyApplicationMyService"); key.Close();

Now that you know how to do it, we also recommend you to read what each of these means. It’s essential, and will only help you to make sure the changes you make are correct.

What makes a Registry Key?

If you imagine “Key” as a folder, the rest of them are different types of file types that store various kinds of values. So if you build an application, you can have a master folder, and then subfolders to separate one set from another. Here is a bit about each of them:

DWORD &  QWORD: Double Word can store a 32-bit unit of data, while QWORD can store 64-bit of data.  

String Value (REG_SZ): It can store either a Unicode or an ANSI string, and contains a null at the end.

Multi-String value: When you want to store multiple numbers of String Value, you can use this. However, make sure to terminate it by an empty string (). Here is a simple example:


Note “” at the end marks the end of the first string, and the last marks the end of the multi-string.

Binary Value: The simplest of all – it contains 0 and 1.

We hope that you find this post useful.

How To Extract Rar, 7Z, Gz Files On Windows 11

On Windows 11, you can open and extract archive formats, such as RAR, 7z, and GZ, and in this guide, you will learn two ways to complete this task. Files with “.rar,” “.7z,” “.gz,” “.tar.gz.” extensions are containers created using Unix-based archival applications, which you may find on Linux and macOS systems. Usually, they are used for backups and archival, including distributing applications over the internet.

Windows 11 includes native support to extract “.gz” and “.tar.gz” files but support “.rar,” “.7z,” and other formats won’t arrive until later in 2023. However, you can use third-party tools like 7zip to open and extract these files.

7zip is a free and open-source file manager available on Windows, macOS, and Linux that you can use to open and extract virtually any kind of archival format, including “.rar,” “.7z,” “.gz,” “.tar.gz.,” “.iso,” “.img,” “.vhdx,” “.dmg,” “.cab,” “.zip,” and many others. You can even open files protected with a password (as long as you have the password to unlock it). Of course, you can always use WinRAR, but even though you can use it for free, you must pay to access additional features.

This guide will teach you the steps to open and extract RAR, 7z, and GZ files on Windows 11.

Extract RAR, 7z, GZ files using 7zip

Since Windows 11 doesn’t include native support to manage archival containers, such as RAR, 7z, and GZ, you will have to rely on free third-party tools, such as 7zip.

Install 7zip

To install the 7zip app on Windows 11, use these steps:

Type the following command to install the 7zip app on Windows 11 and press Enter:

winget install --id 7zip.7zip

Once you complete the steps, you can use the app to open and extract virtually any kind of archival file format.

Extract RAR, 7z, GZ files

To open and extract a  RAR, 7z, or GZ file format on Windows 11, use these steps:

Open Start.

Open the folder with the RAR, 7z, or GZ to open.

Quick note: If the file is large, uncompressing and opening may take a while. If you close the app without extracting the contents, you will have to uncompress the file again.

Select the files to extract from the container.

Specify the folder location.

After you complete the steps, the contents of the archival container will extract to the destination folder.

Extract RAR, 7z, GZ files using WSL

Alternatively, if you use the Windows Subsystem for Linux, you can install the P7Zip app to open and extract RAR, 7z, and GZ files using commands.

Install P7Zip

To install P7Zip on WSL, use these steps:

Open Start.

Type the following command to spin the WSL (Ubuntu) distro and press Enter:


Type the following command to check that the local package index is up to date and press Enter:

sudo apt update

Type the following command to install P7Zip in the WSL distro and press Enter:

sudo apt install p7zip-full p7zip-rar

Type “Y” and press Enter to continue with the installation.

(Optional) Type the following command to confirm the app has been installed and press Enter:


Once you complete the steps, you can use the Ubuntu terminal to extract RAR, 7z, and GZ files on Windows 11.

In the case you are dealing with a RAR or Zip folder with a password, the app will prompt you to enter the authentication information during the extraction process or when trying to open a specific file.

If you have a RAR file divided into multiple files, you only need to open the first one, and during the extraction process, 7Zip will reassemble and extract the files accordingly.

Extract RAR, 7z, GZ files

To open and extract a RAR, 7z, or GZ file format on Windows 11, use these steps:

Open Start.

Type the following command to spin the WSL (Ubuntu) distro and press Enter:


Type the following command to move to the folder containing the RAR, 7z, and GZ files and press Enter:

Quick note: On Linux, when specifying a path, you have to use “/” not “” like on Windows. Also, in the command, update the path with the location where your archival files are located.

(Optional) Type the following command to view details about the archival container before extracting it, and press Enter:

7z l FILE-NAME.rar

In the command, replace “FILE-NAME.rar” with the actual name of your file.

Type the following command to unrar a file and press Enter:

7z e FILE-NAME.rar

In the command, replace “FILE-NAME.rar” with the actual name of the file to extract.

(Optional) Type the following command to extract the file to a specific folder and press Enter:

7z e chúng tôi -oc:/mnt/c/PATH/EXTRACTION/

In the command, replace “FILE-NAME.rar” with the actual name of the file and update the path to the folder you want to extract the contents.

After you complete the steps, the files from the RAR, 7z, or GZ container will extract into the folder you specified.
