The Microsoft-implemented POSIX function name read is a deprecated alias for the _read function. By default, it generates Compiler warning (level 3) C4996. The name is deprecated because it doesn't follow the Standard C rules for implementation-specific names. However, the function is still supported.

I've incremented the Pure java code originally posted by David to allow acessing the 32-bits section of the registry from a 64-bit JVM, and vice-versa. I don't think any of the other answers address this.

I've done this before using jRegistryKey. It is an LGPL Java/JNI library that can do what you need. Here's an example of how I used it to enabled Registry editing through regedit and also the "Show Folder Options" option for myself in Windows via the registry.

In the end it depends on what you're wanting to do: storing preferences for your app is what the Preferences does just great. If you're wanting to actually change registry keys not having to do with your app, you'll need some JNI app, as described by Mark (shameless steal here):

Thanks to original post. I have reskinned this utility class and come up over the flaws which it had earlier, thought it might help others so posting here. I have also added some extra utility methods. Now it is able to read any file in windows registry(including REG_DWORD, REG_BINARY, REG_EXPAND_SZ etc.). All the methods work like a charm. Just copy and paste it and it should work. Here is the reskinned and modified class:

The best way to write to the register probably is using the reg import native Windows command and giving it the file path to the .reg file which has been generated by exporting something from the registry.

However, a pirate called David Croft has worked out that it's possible to use methods in Sun's implementation of the Preferences API for reading the Windows registry from Java without JNI. There are some dangers to that, but it is worth a look.

The Preferences API approach does not give you access to all the branches of the registry. In fact, it only gives you access to where the Preferences API stores its, well, preferences. It's not a generic registry handling API, like .NET's

The java.util.prefs package provides a way for applications to store and retrieve user and system preferences and data configuration. These preference data will be stored persistently in an implementation-dependent backing stored. For example in Windows operating system in will stored in Windows registry.

This one launches reg.exe under the covers, reading/writing to temporary files. I didn't end up using it, but it looks like a pretty comprehensive implementation. If I did use it, I might dive in and add some better management of the child processes.

This uses the same Java internal APIs as in in David's answer, but I've rewritten it completely. It's shorter now and nicer to use. I also added support for HKEY_CLASSES_ROOT and other hives. It still has some of the other limitations though (such as no DWORD support and no Unicode support) which are due to the underlying API and are sadly unavoidable with this approach. Still, if you only need basic string reading/writing and don't want to load a native DLL, it's handy.

will do all the magic. I have tried it, while making jar as windows service using servany.exe which requires changes to made in registry for adding javaw.exe arguments and it works perfectly. You might want to read this:

I only want read access, not writing any bytes on the filesystem (my Linux system being currently suspended on disk).
A better option would be able to export directories as a tar archive in order to keep permission and attributes.

You can choose to mount it read-only after installation by modifying the registry entries in HKLM\SYSTEM\CurrentControlSet\Services\btrfs, and I've found it to be very stable (if a bit slow) even with six mounted Btrfs partitions and very frequent reads from one of them.

It does support writes to the disk, but as the software is still in development (and comes with the important disclaimer that "YOU USE IT AT YOUR OWN RISK. I take NO RESPONSIBILITY for any damage it may do to your filesystem. DO NOT USE THIS DRIVER UNLESS YOU HAVE FULL AND UP-TO-DATE BACKUPS OF ALL YOUR DATA"), it's probably inadvisable to not mount it read-only. (Unfortunately, by default it mounts with writes enabled, so you do have to go into the registry and change that. You should definitely have backups, in any case.)

In VBOX you can create a virtual disk device pointing to the raw disk device. You can also do this with VMWARE with an online vm creator or workstation trial then use vmware free player and of course you can do this in HyperV for free.

Quick Update: While WinBtrfs is your best bet to make Windows work with Btrfs, WSL2 should be your best native solution to get access to your files. You Install WSL via Programs and Features, then go to Terminal and execute wsl.exe --install -d Ubuntu. All your drives should be mounted automatically in /mnt. However, take care with the correct mount options of your Btrfs partitions, as usual.

Working in a multi-platform environment is a daily occurrence in schools, companies, in the studio, and on set. With MacDrive installed on your Windows PC, you can easily share files to and from APFS and HFS+ formatted internal drives, portable and desktop multi-bay drives, and even iPads. Regardless of the platform, you can read and write to the drive and then share those files. MacDrive gives you fully compatible and reliable out-of-this-world data sharing convenience.

MacDrive 11 is the most powerful solution for APFS disks available. With more features and protection MacDrive is the easy choice for accessing APFS disks on Windows. See how MacDrive beats the competition.

When you transform your PC with the power of MacDrive, you become a double-duty dynamo with complete Mac disk management. You can open, edit, and save files directly on Mac disks from any application. You can even format, create, and delete partitions on Mac disks making it possible to share data between computers like never before.

With the release of MacDrive 11, it has proven to be much more useful to me than Paragon APFS for Windows which I have used for years. Paragon APFS can only view the last APFS volume in the disk with no way to switch to other volumes. With MacDrive 11, I am able to switch APFS volumes with ease and can also see APFS snapshots on my backup disk which contains a very complex layout with 6 APFS volumes, 3 snapshots and one NTFS volume. It is my hybrid backup external drive for both Mac/Windows laptops.

I have recently tried your product (recommended by an Instructor) and was very impressed! Your software recovered a drive that I thought was gone forever. I am interested in your product at the academic level as the school uses Macs and I have PC at home.

1 Copying from an OWC ThunderBlade formatted APFS with (4) 1TB blades to a HP Spectre, Windows 11 (22H2), 16GB RAM, 11th Gen i7 @ 2.8GHz. Copy set was one folder containing 30 video files comprising 46GB.
2 To view Time Machine backups on APFS disks, you will need to turn on Hidden Items under the View menu in File Explorer. Seamless access for Time Machine backups on APFS disks is coming soon.

Programmatically in rust or in general? Because there are many tools to find metadata on binaries on windows. Even though, you could still spawn a process and read the output. Depending on what you are going to look for, there are different tools you may need, for example if you want to check whether a binary is a .NET app, you could use dumpbin if I recall, and some other tools for other metadata. It all depends on what you want to do.

I don't think the file version is part of PE metadata. It is instead part of another set of metadata which is embedded as a resource in the EXE or DLL. You will need to call Windows API GetFileVersionInfo to get that. See this StackOverflow question for example code in C++. You can write the equivalent in Rust. For that the winapi crate may come in handy.

I had previously used WD My Cloud on Windows 7. Everything always worked as it should. Enter Windows 10. What a disaster! I can see My Cloud on my network, have access to all files. But I can change or delete NOTHING! Everything is up to date: Windows 10, My Cloud firmware. I have entered my credentials where called for in Control Panel. I have changed the registry. Nothing works!

First, have you accessed the My Cloud Dashboard user interface and ensured the User account you are using to access the My Cloud has Full Access to the Share (I assume the Share is configured as a Private Share) that your trying to access? One of the User permission settings when setting a Share to Private is Read Only access.

Second, you may want to read through the Compilation of Windows 10 Methods, Steps and Solutions thread tacked at the top of this subforum to see if there is anything in there that may affect or solve your issue. Windows 10 has problems in certain instances with the My Cloud, most of those problems are caused by Microsoft Windows 10 operating system and not necessarily the WD MY Cloud device.

What troubleshooting steps have you done? Have you rebooted both the computer and the My Cloud? Did you recently update the firmware for the My Cloud? If so from what version to what version? If not what firmware version (located on the Dashboard) are you using? If you have mapped a drive have you removed that mapping then remapped?

Other ways to test and isolate the problem. Do you have another computer or mobile device you can test to see if its the Windows 10 computer or the My Cloud? Have you tried using the WD My Cloud Desktop for Windows software to copy a file (or files) to the My Cloud?

I noticed that I also could not copy a file to the Public folder on my windows 10 laptop. I went downstairs and on my desktop mapped the Public folder and copied a file to it. So I went back to the laptop and disconnected the mapped Public folder. Then I remapped it and was able to copy from the laptop to the Public folder. My Public folder was mapped before the firmware upgrade. It was not mapped on my desktop. So the solution may be as simple as disconnecting and remapping.
