A Microsoft Certified Refurbisher (MCR) is a company or organization that specializes in refurbishing and selling used computers with genuine Microsoft software. These refurbishers are authorized by Microsoft to install genuine Windows operating systems and other Microsoft software on refurbished computers.
To become a Microsoft Certified Refurbisher, an organization must meet certain requirements and follow specific guidelines set by Microsoft. These guidelines include ensuring that all refurbished computers have genuine Microsoft software, providing a warranty on refurbished products, and adhering to strict data security and privacy policies.
By purchasing a refurbished computer from a Microsoft Certified Refurbisher, consumers can be assured that they are getting a quality product with genuine Microsoft software, at a lower cost than buying a new computer. Additionally, by purchasing a refurbished computer, consumers are helping to reduce electronic waste and support sustainability efforts.

QC (Quality Control) standards are a set of guidelines and procedures established to ensure that products and services meet specific quality requirements. These standards are often developed by organizations such as the International Organization for Standardization (ISO) and are widely recognized as a way to demonstrate a company's commitment to quality.
QC standards can cover a range of areas, including manufacturing processes, product design, customer service, and employee training. They typically outline specific requirements and guidelines for each area and provide a framework for measuring and monitoring quality levels.
Adhering to QC standards can provide several benefits for organizations, including improved customer satisfaction, increased efficiency, reduced costs, and a competitive advantage in the marketplace. Many customers and suppliers require companies to meet specific QC standards to ensure consistency and quality in their products and services.
Examples of QC standards include ISO 9001 for quality management systems, ISO 13485 for medical devices, and Six Sigma for process improvement. Compliance with these standards requires ongoing monitoring and measurement of key performance indicators to ensure that quality levels are maintained and improved over time.

An extended warranty is a service offered by manufacturers or third-party companies that extends the original warranty period on a product beyond its standard coverage. This type of warranty typically covers repairs or replacements for certain types of damages or malfunctions that occur after the original warranty expires.
After-sales services are a range of services provided by manufacturers or retailers to customers after the sale of a product. These services may include installation, repair, maintenance, and support. After-sales services are designed to enhance the customer's experience with the product and to ensure that the customer is satisfied with their purchase.
Both extended warranties and after-sales services can provide peace of mind to customers who want to protect their investment and ensure that they have access to support if anything goes wrong with their product. However, it's important to carefully consider the terms and conditions of these services before purchasing them, as they can vary widely in terms of coverage, cost, and value. It's also important to compare the cost of these services to the cost of simply replacing the product in the event of a malfunction or breakdown.

Genuine Windows OS refers to a copy of Microsoft Windows operating system that is licensed and activated by Microsoft, and is not a pirated or counterfeit version. A genuine Windows OS ensures that the user has access to all the features and updates provided by Microsoft, and also ensures that the system is secure and free from malware or other harmful programs.
To ensure that you have a genuine Windows OS, it is recommended that you purchase it from a legitimate source and activate it using a valid product key. Microsoft provides various tools and resources to help users verify the authenticity of their Windows OS, such as the Windows Genuine Advantage program, which can check the validity of the installed OS and product key.
Using a genuine Windows OS is not only a legal requirement, but also ensures that you receive regular security updates and support from Microsoft, and helps to protect your system from potential security threats.

Door delivery PC refers to a computer system that is delivered directly to the customer's doorstep after being ordered online or over the phone. Many computer manufacturers and retailers offer this service to make it more convenient for customers to purchase and receive their new computer.
When you order a door delivery PC, you can typically choose the specific hardware and software components you want, such as the processor, memory, storage, and operating system. The computer is then assembled, tested, and shipped to your address.
Door delivery PCs can be a convenient option for those who may not have easy access to a physical computer store, or who prefer the convenience of shopping and buying online. However, it is important to ensure that you are purchasing from a reputable and trustworthy seller to avoid scams or receiving faulty or low-quality components.
When your door delivery PC arrives, it is important to carefully inspect it for any damage during shipping or any missing components. It is also a good idea to test the computer thoroughly to ensure that everything is working properly and to address any issues or defects as soon as possible.
