Microsoft provides ISO downloads for Windows 10 Home, Windows 10 Pro, and Windows 10 Education through this tool. The current version available for download is 22H2 for Home and Pro editions.

If you need upcoming features or early builds, Microsoft sometimes releases VHDX files for Insider builds. Check the Windows Insider ISO download page and filter by “VHDX”.

Windows 10 Virtual Hard Disk (VHD) images serve as a cornerstone for modern IT deployment, development, and disaster recovery. Unlike standard ISO files—which are disc images used for installation—a VHD image is a pre-configured "hard drive in a file" that can be booted immediately by a virtual machine or even by physical hardware through native boot. Accessing Windows 10 VHD Images

When creating images from scratch, always choose the newer .vhdx format. It features power-failure resiliency, better performance, and supports disk sizes up to 64 TB compared to the 2 TB limit of legacy .vhd files.

Virtual Hard Disk (VHD) and VHDX files are powerful tools for IT professionals, developers, and tech enthusiasts. Downloading or creating a Windows 10 VHD image allows you to run a full version of the operating system inside a virtual machine (VM) or boot it directly alongside your host OS without modifying your existing desktop partition.

Windows 10 VHD images are official virtual hard disk files Microsoft provides for developers, testers, and IT pros to quickly boot preconfigured Windows 10 environments in virtualization platforms (Hyper-V, VirtualBox, VMware with conversion). They are typically time-limited evaluation images that include tools like Edge and developer workloads.

Visit: https://developer.microsoft.com/en-us/windows/downloads/virtual-machines/ – choose “Windows 10” and “Hyper‑V” (VHDX) format.

Start the VM, run through the standard Windows 10 setup, and activate it with your product key.

Dynamic disks grow as you add files, saving host storage space. Fixed disks allocate the total size immediately, offering slightly faster read/write performance.

: Run the tool as an administrator, select your system drive (usually ), and click . It will generate a VHDX/VHD file of your live system. Windows Install to Virtual Machine

Choose your platform: , VMware , VirtualBox , or Parallels . Download the .vhd or .vhdx file.

Length information

The two equivalent length bytes in the telegram header of the variable format contain the number of information bytes in the body of the telegram. These include: DA, SA, FC and the PDU. The value ranges from 4 to 249, so that no more than 246 bytes can be transferred to the PDU of a telegram. No value <4 is allowed, because a telegram must comprise at least one DA, SA ,FC and a data byte. The longest telegram therefore comprises 255 bytes overall.

7	6	5	4	3	2	1	0	LE and LEr: length byte

The FCS (Frame Check Sequence) checksum required in the telegram for Hamming distance 4 is always located directly in front of the end delimiter (ED) and has the following configuration:

7	6	5	4	3	2	1	0
0 to 255								Checksum

For the without-data format (SD1) the checksum must be formed by the arithmetical sum of DA, SA, and FC without start delimiter (SD) or end delimiter (ED) and disregarding sums carried over. For the fixed length format with data (SD3) and the variable length format (SD2) the checksum must also include the payload (PDU). Example of bytes added together in the FCS:

The two address bytes in the telegram header of telegrams (Request, Confirmation and Response telegrams) contain the station’s destination address (DA) and source address (SA).

7	6	5	4	3	2	1	0	DA: Destination address
	0 — 127 (0x7F)							Destination address
0 1								no DSAP (SAP = NIL) DSAP present

7	6	5	4	3	2	1	0	SA : Source address
	0 – 126 (0x7E)							Source address
0 1								no SSAP (SAP = NIL) SSAP present

Address 127 is reserved as a global address for broadcast or multicast messages (telegrams to all bus users or user groups selected via service access point; only allowed with Send Data with No Acknowledge, SDN). The address byte of the Request telegram should be reflected in the Response telegram in reverse, i.e. the SA byte of the Response telegram contains the destination station address and the DA byte the source station address of the Request. For formats with a PDU, the address extension serves to identify a destination and/or source address extension in the form of a Service Access Point (SAP) that immediately follows the FC byte in the PDU. The address extensions of a Request telegram must be reflected in the Response telegram in reverse. If the address extension bit has not been set, it is the special SAP = NIL. This Service Access Point has the advantage that its telegram is 2 bytes shorter and is therefore used for cyclic data exchange.
