Windows PE - Unknown software exeption 0xc000001d

[Tom1969]

TestScript:

    $Result = 2 ^ 16
    MsgBox(0, "Result", $Result)

Compile the Script:

• Autoit 3.3.14.2 or 3.3.15.0
• 64bit

Test-Scenario:

• Boot Windows 8.1 x64 Installmedia from USB or DVD
• Press Shift-F10 to open command shell
• Run Script

Result depends on CPU-Type:

Broadwell, Hasswell or Skylake

• unknown software exeption (0xc000001d)

Ivybride and older CPU

• script works fine

Alternative tests :

• Boot Windows 10 x64 Installmedia -> same problem

• Boot Windows 8.1 x64 or Windows 10 x74 Installation from Harddisk -> No problem on every CPU-Type

• Compile with Autoit 3.3.12.0 -> No problem on every CPU-Type

Windows PE is not Windows, the fact that it works at all on Windows PE is a good thing, that things don't work with Windows PE is not at all surprising. After 3.3.12.x AutoIt was compiled to work with XP SP3 and above, so it's probably something related to that change causing the issue.

I confirm this exception on two computer. Autoit 3.3.12 works fine, 3.3.14.2 throws this exception

As AutoIt does noes really support Win_PE This will not be fix.
The change perhaps occurred with the removing support of Windows_XP
