Unfortunately not visible if you only look for V10-updates
on the support-page:
open the "Version and platform-filter" for all versions and-
like a wonder- it appears:
BE5484RSP4_282008.EXE - VERITAS Backup Exec (tm) 10.0 for Windows Servers revision 5484 - Service Pack 4 - Includes Critical Security Updates - 02/24/2006
Would appreciate to have information about the changes.
regards
