What is Windows Enterprise LTSC?

 

Enterprise LTSC (Long-Term Servicing Channel) is a long-term support variant of Windows 10 Enterprise, released every 2 to 3 years. Each release is supported with security updates for either 5 or 10 years after its release, and intentionally receives no feature updates.

Microsoft releases Windows 10 and 11 through two servicing channels.

 

GAC (General Availability Channel)

It is intended for both general and enterprise customers.

Edition examples include options such as Home, Pro, and Enterprise.

Maximum support on the same build is usually 2 years for consumers and 3 years for the enterprise. After that, you need to install feature updates.

This is the main servicing channel and other software and games usually follow this channel's life cycle to provide support.

LTSC (Long-Term Servicing Channel)

It is designed for devices where functionality and features must remain constant over time, such as medical systems, industrial controllers, and air traffic control devices.

Examples of editions include: Enterprise LTSC and IoT Enterprise LTSC.

Maximum support on the same build is usually 5 years for LTSC and 10 years for the IoT LTSC.

This is not the main servicing channel and other software and games usually don't follow this channel's life cycle. For example, browsers and games might not provide support for 10 years on same build.

It lacks most of the Store (UWP) apps.

Reasons to use LTSC:

You don't like annual Windows feature upgrades.

You don't like preinstalled Store (UWP) apps as well.

You want longer update support for Windows 10.

Reasons to avoid using LTSC:

As stated above, many games and software might not support LTSC once that same build has reached the end of life in GAC.

Games might not work out of the box and you will manually need to install store and Xbox apps.

New hardware might not be fully supported by a 2-3 year-old LTSC build (A new version of LTSC is released every 3 years).

You might miss new features added in GAC that aren't available in LTSC.

IP switch command

If you have two internet connections and want to manually switch between them using the command line, you can do this by changing your IP address, subnet mask, and gateway for your network interface

netsh interface ipv4 set address name="Ethernet" static 10.70.72.10 255.255.255.0 10.70.72.20

netsh interface ipv4 set dns name="Ethernet" static 8.8.8.8

netsh interface ipv4 add dns name="Ethernet" 8.8.4.4 index=2

IP switch command

netsh interface ipv4 set address name="Ethernet" static 10.70.72.10 255.255.255.0 10.70.72.20

netsh interface ipv4 set dns name="Ethernet" static 8.8.8.8

netsh interface ipv4 add dns name="Ethernet" 8.8.4.4 index=2

Windows 11 shared pc acces problem

After a Windows 11 update, shared folders on a PC may become inaccessible due to changes in network discovery, file sharing, or security settings.

Creating a copy of a physical hard drive (HDD), including its operating system (OS), to a virtual hard drive (VHD) image

Creating a copy of a physical hard drive (HDD), including its operating system (OS), to a virtual hard drive (VHD) image involves several steps. You will essentially be performing a disk cloning process that converts the contents of your physical HDD into a virtual hard disk format. This allows you to run the OS and programs from the virtual disk in a virtual machine (VM).

Here’s how you can do it:

Requirements:

• A virtualization software (e.g., VMware, VirtualBox, Hyper-V) that supports virtual hard disk (VHD or VDI) formats.
• Disk cloning software like Clonezilla, Macrium Reflect, or Acronis True Image.
• A working physical machine with the OS you want to copy.
• Sufficient storage space for the virtual HDD image.

Steps to Create a Virtual HDD Image from a Physical HDD

1. Prepare the Tools

• Install a virtualization software such as VirtualBox, VMware Workstation, or Hyper-V.
• Install a disk cloning tool like Clonezilla (free), Macrium Reflect (free and paid), or Acronis True Image.

2. Clone the Physical HDD to an Image File

• Use your disk cloning software to create an image of the physical HDD. The image should be stored on an external drive or in a different partition (since it will likely be quite large).
• Most tools will allow you to create a disk image (e.g., .iso, .img) or clone the entire drive sector by sector.

Example with Macrium Reflect:

• Open Macrium Reflect and select the source disk (the physical HDD).
• Choose “Create an image of the partition(s)” option and select a destination where you want to save the image.
• Complete the imaging process.

3. Convert the Image to a Virtual HDD

If the cloning software creates an image file (like .img), you can convert it to a VHD or VDI format, which can be used by virtualization software.

• Using VirtualBox: You can use the VBoxManage command to convert the image into a VirtualBox-compatible virtual disk.

Copy

VBoxManage convertfromraw /path/to/image.img /path/to/vm_disk.vdi --format VDI

• Using VMware: VMware has a tool called vCenter Converter that can convert physical disks to virtual ones.
0. Install VMware vCenter Converter.
1. Run the tool and select the option to convert a physical machine.
2. Follow the wizard to create a virtual machine and select a destination in VMware.

4. Create a Virtual Machine and Attach the Virtual HDD

Once you have the virtual hard disk (VHD/VDI), you need to create a virtual machine and attach the newly created virtual disk.

• In VirtualBox:
0. Open VirtualBox and create a new virtual machine.
1. When it asks for a hard disk, select “Use an existing virtual hard disk file” and choose the .vdi file you just created.
2. Proceed with the rest of the VM setup and boot up.
• In VMware:
0. Create a new virtual machine.
1. When it prompts for a disk, choose to use an existing disk and select the .vmdk or .vhd file.
2. Complete the setup and start the VM.

5. Adjust the Virtual Machine Settings

Depending on the hardware and OS, the VM might not boot correctly right away. You may need to make adjustments:

• Install VMware Tools or VirtualBox Guest Additions for improved compatibility with the virtual environment.
• If there are issues with drivers (e.g., storage controllers), you may need to change settings for the virtual machine's virtual hardware (e.g., IDE, SATA, etc.).
• You might also need to adjust network or display settings for better performance.

6. Boot the Virtual Machine

Once everything is set up, start the virtual machine. The system should boot from the virtual disk, and you should have access to the same OS and programs you had on the physical machine, running in a virtualized environment.

---

Additional Notes:

• Sysprep: Before cloning your physical machine, it is recommended to run Sysprep (System Preparation Tool) on Windows to generalize the OS. This removes hardware-specific information and ensures the virtual machine can adapt to virtual hardware without issues.
• For Windows: sysprep /oobe /generalize /shutdown
• Performance: Virtual machines might have lower performance compared to a physical machine, especially for graphics-intensive applications. Ensure that you allocate sufficient resources (RAM, CPU) to the VM.

Conclusion:

By using disk cloning tools and virtualization software, you can successfully create a copy of your physical HDD and boot it as a virtual machine. The key steps are cloning the physical drive to an image, converting the image to a compatible virtual disk format, and configuring the virtual machine to run from that disk.
