Я инициировал расшифровку диска bitlocker из окна восстановления Windows 8. Есть признаки, сколько времени это займет?

устал от командной строки натыкаясь, чтобы увидеть. Это показывает состояние, прогресс, предполагаемое время для завершения. Чтобы выйти, ctrl-c или останавливается при преобразовании

# Description: DecryptRemainingStatus   
# 
#    1. Escalates to administrator (if not already)
#    2 Uses the "Write-Progress" to create a bar and provide some status
#       information (as well as anticipated length based on current) for
#       decryption status
#
# NOTE:  You need executable status for powershell scripts.  If you get an error:
# If you downloaded this, you need to unblock the script
# See what your current execution ability is:
#   Get-ExecutionPolicy
# Set it to something reasonable (temporarily)
#   Set-ExecutionPolicy -ExecutionPolicy RemoteSigned
# Don't forget to reset it to whatever it was before (In this case, Restricted) after your run the script
#  Set-ExecutionPolicy -ExecutionPolicy Restricted
# 
# @Params
# 
# -seconds [number of seconds in each monitor interval, defaults to 5]
#
# @example:
#
# PS>.\DecryptRemainingStatus.ps1 -Seconds 10
#
# Get "Seconds" param
#
[CmdletBinding()]param(
    [int]$Seconds = 5
)
# Set-PSDebug -Trace 1

#elevate to "Administrator" (Required for manage-bde)
