|
|
|
|
When you activate a computer running Windows 10, the following information is sent to Microsoft:
|
|
|
|
- The Microsoft product code (a five-digit code that identifies the Windows product you're activating)
|
|
- A channel ID or site code that identifies how the Windows product was originally obtained
|
|
|
|
For example, a channel ID or site code identifies whether the product was originally purchased from a retail store, obtained as an evaluation copy, obtained through a volume licensing program, or preinstalled by a computer manufacturer.
|
|
|
|
- The date of installation and whether the installation was successful
|
|
- Information that helps confirm that your Windows product key hasn't been altered
|
|
- Computer make and model
|
|
- Version information for the operating system and software
|
|
- Region and language settings
|
|
- A unique number called a *globally unique identifier*, which is assigned to your computer
|
|
- Product key (hashed) and product ID
|
|
- BIOS name, revision number, and revision date
|
|
- Volume serial number (hashed) of the hard disk drive
|
|
- The result of the activation check
|
|
|
|
This result includes error codes and the following information about any activation exploits and related malicious or unauthorized software that was found or disabled:
|
|
|
|
- The activation exploit's identifier
|
|
- The activation exploit's current state, such as cleaned or quarantined
|
|
- Computer manufacturer's identification
|
|
- The activation exploit's file name and hash in addition to a hash of related software components that may indicate the presence of an activation exploit
|
|
- The name and a hash of the contents of your computer's startup instructions file
|
|
- If your Windows license is on a subscription basis, information about how your subscription works
|
|
|
|
Standard computer information is also sent, but your computer's IP address is only kept temporarily.
|
|
|
|
## Use of information
|
|
|
|
Microsoft uses the information to confirm that you have a licensed copy of the software. Microsoft doesn't use the information to contact individual consumers.
