如何查询Win8密钥?
品牌电脑如何获取Win8.1 OEM密钥?
现在消费者用户购买新款品牌电脑时,厂家一般会预装OEM版Win8系统,即Win8简体中文版。由于微软对OEM版Win8采用全新激活方式,即OA 3.0激活技术,告别之前Vista、Win7时代品牌电脑的正版Windows
Win8 OEM 3.0激活方式,即每台OEM机器都必须对应唯一的密钥,因此,OEM厂商需要将唯一的Windows8密钥写入每台新Win8电脑的BIOS主板信息,当用户第一次使用时,需要联网激活。

一、首先如何判断自己新电脑预装了OEM版Win8系统?
操作如下:
1、使用Win+R组合键打开“运行”窗口,输入slmgr.vbs -dlv

2、Win8/Win8.1系统会自动生成一个脚本信息,记录当前的系统信息(在系统描述中,如果显示OEM_DM channel,可以判断为OEM版Win8系统)

二、如果Win8用户需要重新安装时Windows RT、Windows 8/Windows 8.1时,需要重新输入Win8密钥完成联网激活,但这时却找不到电脑自带的Win8密钥。这次整理三种快捷方法帮助用户揪出预装Win8/Win8.1电脑OEM密钥。
方法一:全能硬件工具AIDA64 v4.0 (点击这里下载)
操作如下:
打开AIDA64工具,在左侧菜单依次选择主板》ACPI,在右侧表描述中选择“MSDM:Microsoft Data Management Table”,在该项目底部(SLS Data)会显示当前Win8 OEM完整密钥。

方法二:产品密钥查询工具Product Key (32位版本,56KB;64位版本,71KB,点击这里下载)
操作如下:
下载解压小工具,运行ProduKey.exe主程序,就可以查询当前系统的Win8 OEM 25位完整密钥。

方法三、无需第三方工具,系统原生命令行 (支持Windows8、Windows 8.1、Windows RT全平台)
操作如下:
1、使用组合键Win+Q,或者将鼠标移至屏幕右下角,打开Charm超级菜单中搜索功能
2、输入PowerShell,搜索PowerShell组件
3、右击Windows PowerShell,以管理员身份运行
4、在PowerShell窗口下输入以下命令:(注:英文字符)
(Get-WmiObject -query‘select * from SoftwareLicensingService’).OA3xOriginalProductKey

5、随后,Windows PowerShell自动显示当前Win8 OEM完整密钥。
现在,Win8/Win8.1用户揪出预装Win8/Win8.1电脑OEM密钥后,就可以很轻松重装当前Win8系统,随后用该密钥联网激活。

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.
