In the past, Microsoft has released Service Packs to operating systems, which provide incremental updates, which provide security updates to the existing operating system.
These incremental updates have typically not required decrypting disks, or uninstalling Symantec Encryption Desktop prior to the upgrade in order to apply these service packs.
Microsoft has released Windows 8.1, which is a major upgrade to Windows 8.
As this is a major upgrade, it is required to follow the standard procedures outlined in the User Guides concerning major OS upgrades.
Upgrading Windows 8 to Windows 8.1 will require following the same process in upgrading as outlined in the User's Guide:
1. Back up your keys and keyrings before uninstalling. 2. If you have used Symantec Drive Encryption, decrypt your disk before you uninstall Symantec Encryption Desktop. 3. Uninstall any previous versions of Symantec Encryption Desktop before upgrading to the new version of the operating system. This applies whether the system is encrypted or not. 4. Once you have upgraded your version of the operating system, reinstall Symantec Encryption Desktop. Import your keys/keyring and, if necessary, you can then encrypt your disk.
Once the operating system is installed, it is then possible to install Symantec Encryption Desktop 10.3.1 MP1 and re-encrypt the drives as normal.
Because early support was achieved to support Windows 8.1, the release notes for Symantec Encryption Desktop 10.3.1 and 10.3.1 MP1 don't state support for Windows 8.1 specifically. These versions of Symantec Encryption Desktop have since been tested on these operating systems and have been found to be fully supported. This announcement has been made in an alert.
