Download Windows Symbol Packages
Symbol files make it easier to debug your code. The easiest way to get Windows symbols is to use the Microsoft Symbol Server. The symbol server makes symbols available to your debugging tools as needed. After a symbol file is downloaded from the symbol server it is cached on the local computer for quick access. Additional versions of Windows not listed here, are available on the Microsoft Symbol Server.
If you prefer to download the entire set of symbols for a particular version of Windows, download a symbol package.
Note on symbol package deprecation
With the cadence that we release updates for Windows, the Windows debugging symbols we publish via the packages on this page are quickly made out of date. We have made significant improvements to the online Microsoft Symbol Server by moving this to be an Azure-based symbol store, and symbols for all Windows versions and updates are available there. You can find more about this in this MSDN blog entry. Going forward we will no longer publish the offline symbol packages for RTM releases.
Symbol Package System Requirements
Before downloading and installing each symbol package, you should have at least 1 GB of disk space free, because of the size of the download package and required temporary files:
- Each x86 symbol package may require 750 MB or more of hard disk space.
- Each x64 symbol package may require 640 MB or more.
- Symbol packages are non-cumulative unless otherwise noted, so if you are using an SP2 Windows release, you will need to install the symbols for the original RTM version and for SP1 before you install the symbols for SP2.
The symbol download packages are listed by processor type (x86, and x64) and build type (retail and checked). Almost all customers require the symbols for the retail version. If you are debugging a special version of Windows with extra debugging information, then you should download the symbols for the checked version.
