Last updated: 2020-03-30 14:36:56


This document introduces the custom configuration of a Windows CVM.
Different from quick configuration, custom configuration provides full options, and you can choose the appropriate configuration based on your needs.


  1. Before starting the custom configuration, you need to complete Step 1 in Getting Started with Windows CVM.
  2. Go to the Tencent Cloud official website, select Products -> Cloud Compute & Network -> Cloud Virtual Machine, and click Buy Now to enter the CVM purchase page.
  3. Click Custom Configuration to go to the custom configuration page.

Selecting Region and Model


  1. Select the Postpaid billing method (users who cannot purchase postpaid CVMs need to complete Identity Verification first).

  2. Select a region and an availability zone. When you need more than one CVM, it is recommended that you choose different availability zones to implement disaster recovery.

  3. Select a model and configuration.
          Based on different underlying hardware, Tencent Cloud offers two series of instances: Series 1 and Series 2 (also referred to as last-generation instance and current-generation instance). They respectively provide the following instance types:

Series and models vary with different areas and availability zones.

Selecting an Image


  1. Select an image provider.
    Tencent Cloud supports public images, custom images, shared images, and service marketplace images. Select one by referring to Image Types.
    We recommend that users who have just started using Tencent Cloud select public images, which contain the legitimate Windows operating system. You need to build a subsequent operating environment on your own.

  2. Select an operating system: Windows.

  3. Select a system version.

    • Suitable for running programs developed under Windows, such as .NET.
    • Support SQL Server and other more databases (you need to install it yourself).

Click Next Step: Select Storage and Network to enter the storage and network selection page.

Selecting Storage and Network


  1. Select the type of disk and the size of data disk.

    Tencent Cloud provides cloud disk, local disk and SSD cloud disk (The system disk size is optional, which defaults to 50 GB).

    • Cloud disk: Deliver high data reliability with the distributed three-copy mechanism.
    • SSD cloud disk: Built upon the full NVMe SSD storage media and Tencent Cloud's CBS 3-copy distributed storage technology, an SSD cloud disk provides I/O capabilities featured by low latency, high random IOPS and high throughput, and high-performance storage with 99.9999999% data security. It is applicable to scenarios which require high IO performance.
    • Local disk: A storage located on the physical machine where the CVM resides, which allows low latency but may cause single point of failure risk. For the comparison, see Product Category.
  2. Select a network type.
    Tencent Cloud provides two network types: basic network and VPC.

    • Basic network: Suitable for new users. CVMs of the same user are interconnected via a private network.
    • VPC: Suitable for advanced users. Different VPCs are logically isolated from each other.

    A Windows CVM cannot be used as Public Gateway. Users who need a public gateway can refer to Getting Started with Linux CVM.

  3. Select public network bandwidth.
    Tencent Cloud provides two options: Bill-by-bandwidth or Bill-by-traffic.

    • Bill-by-bandwidth: Select a fixed bandwidth. Packet loss occurs if this bandwidth is exceeded. This is suitable for scenarios with minor network fluctuation.
    • Bill-by-traffic: The service is charged based on the actual traffic usage. You can set a limit for peak bandwidth to avoid extra fees caused by unplanned traffic. Packet loss occurs when the instantaneous bandwidth exceeds this limit. This is suitable for scenarios with large network fluctuations.
    1. Select quantity.

Click Next Step: Set Information to enter the information setting page.

Setting Information


  1. Set a CVM name: You can name it after creation or name it now.

  2. Set the login information: You can set a password which can be modified after creation of the CVM, or use a system-generated password that is sent to you via the internal message.

  3. Select a security group (Make sure that the login port 3389 is enabled. For more information, see Security Group).

Click the Enable button to log in to the Console to check your CVM.

After the CVM is created, you will receive an internal message containing the instance name, public IP, private IP, login name, initial login password, and other information. You can use these information to log in to and manage your instance. To ensure the security of your CVM, change your Windows login password as soon as possible.

Click here to complete subsequent configurations, including logging in to the Windows CVM, formatting and partitioning the data disk.
