To save drive space, Microsoft has limited offering only the following types of updates from Windows Update to WIMBoot devices with 32GB or less of storage space:
- Critical updates that keep the system or programs running.
- Security updates and security advisory updates.
Users can still manually download and install updates from the Microsoft Download Center.

What this feature does
Update services for Windows includes Windows Update and Microsoft Update:
Information collected, processed, or transmitted
- Windows Update is a service that provides you with software updates for Windows software and other supporting software, such as drivers supplied by device manufacturers.
- Microsoft Update is a service that provides you with software updates for Windows software, as well as other Microsoft software such as Microsoft Office.
The Update Services collect info from your PC that allows Microsoft to operate and improve the services, such as:
- The Microsoft software and other supporting software (e.g., drivers and firmware supplied by device manufacturers) installed on your PC for which the update services have updates available. This helps us determine which updates are appropriate for you.
- Your Windows Update and/or Microsoft Update configuration settings such as whether you want updates automatically downloaded or installed.
- The successes, failures, and errors you experience when accessing and using the update services.
- Plug and Play ID numbers of hardware devices – a code assigned by the device manufacturer that identifies the device (e.g., a particular type of keyboard).
- Globally Unique Identifier (GUID) – a randomly generated number that doesn’t contain any personal information. GUIDs are used to identify individual PCs without identifying the user.
- BIOS name, revision number, vendor, and revision date – info about the set of essential software routines that test your hardware, start the operating system on your PC, and transfer data among hardware devices connected to your PC.
- Manufacturer, Model, Platform Role, and SKU Number—information about the PC used to enable diagnostic investigations into driver installations.
You can use these Update Services by going to Windows Update in Control Panel and checking for updates or changing your settings to allow Windows to automatically install updates as they become available (recommended). Within the Windows Update feature, you can choose whether to opt in to Microsoft Update.
If you choose to get important software updates for your PC, the Windows Malicious Software Removal Tool (MSRT) might be included with these updates. MSRT checks PCs for infections by specific, prevalent malicious software (“malware”) and helps remove any infections found. If the software runs, it will remove the malware listed
on the Microsoft Support website. During a Malware check, a report will be sent to Microsoft with specific info about malware detected, errors, and other info about your PC. For more info, read the Windows Malicious Software Removal Tool privacy statement
Use of information
The data sent to Microsoft is used to operate and maintain the Update Services. It is also used to generate aggregate statistics that help us analyze trends and improve our products and services, including the Update Services.
To generate aggregate statistics, the update services use the GUID collected by the Update Services to track and record the number of individual computers that use the Update Services, and whether the download and installation of specific updates succeeds or fails. The Update Services record the GUID of the computer that attempted the download and installation, the ID of the item that was requested, whether updates were available, and standard computer information.
The MSRT information described above is used to help improve our anti-malware and other security products and services. No information in the MSRT reports will be used to identify or contact you.
If you turn on the Update Services, in order for them to properly function some software components on your system that make up or are directly related to the Update Services will need to be updated from time to time. These updates must be performed before the service can check for, download, or install other updates. These required updates fix errors, provide ongoing improvements, and maintain compatibility with the Microsoft servers that support the service.
If the Update Services are turned off, you won’t receive these updates.
Software updates required to install or update Windows Store apps will be downloaded and installed automatically. These updates must be performed for apps to function properly.
Cookies and tokens
A token is similar to a cookie. It stores information in a small file that is placed on your hard disk by the Update Services server, and is used when your computer connects to the Update Services server to maintain a valid connection. It is stored on your computer only, not on the server. This cookie or token contains information (such as last scan time) in order to find the most recently available updates. It contains information to manage what content should be downloaded to your computer, when that should happen, as well as a GUID to identify your computer to the server.
Information contained in the contents of the cookie or token is encrypted by the server (with the exception of the cookie or token expiration time). This cookie or token is not a browser cookie, so it cannot be controlled with your browser settings. The cookie or token cannot be removed; however, if you don’t use the Update Services, the cookie or token won't be used.
