`Open-Shell` needs to adjust itself after OS upgrade. It seems that
`StartMenuHelper` registration is lost after such upgrade:
http://www.classicshell.net/forum/viewtopic.php?f=7&t=8082#p34821
To fix this registration, administrator rights are required (means user
interaction, UAC).
While this is acceptable in consumer environment, it is typically not
desired in business environment where users typically doesn't have
administrator rights.
This patch allows to run `Open-Shell` in silent upgrade mode that will:
* check if OS version changed (otherwise end immediately)
* perform OS upgrade tasks without any user interraction
Such mode can be then used to create scheduled task that will run this
silent upgrade check on every boot with system rights:
`schtasks /Create /RU "NT AUTHORITY\SYSTEM" /SC ONSTART /TN "Open-Shell OS updgrade check" /TR "%ProgramFiles%\Open-Shell\StartMenu.exe -upgrade -silent"`
#167
Commit 1a5f62a added possibility to hide Lock/Sleep/Hibernate buttons if
they were disabled in system power settings.
Unfortunately this didn't work for Lock button.
To fix the behavior we have to add lock command to `g_StdOptions` array
and then all the checks introduced in 1a5f62a will apply properly.
#173
Latest version of ClassicShell was 4.3.1. There is no reason to display
any warning about very old versions (< 2.0.0).
Besides, this will remove dependency on version.dll which could be misused
for DLL hijacking attack.
