Brute Force/Random password for an Excel protected file : embryonic Powershell exercise

Hi Mates,
only a brief exercise in Powershell.
I would like to know if it is possible to crack Excel password with this scripting language.
Theoretically YES. Practically this is only another opportunity to learn it better.
You can improve it for sure but it's only a good point from which to start and , maybe, go deeper.....
With more diligence you could be able to convert this script to compare some hash.
This is a random password generator ...it's up to you to decide what is the best approach : if you know some information about the secret you can sight better your target and modify the script to exclude some useless calculation. Otherwise you will have to check N passwords /2.....at least (consider it the average).

Powershell --> Powerquick : force active directory replication from a specific domain controller to the remaining others

Hi Mates,
quick and useful : how many times you needed to replicate an Active Directory change to the entire domain ?.....quickly, without waiting the system times.
The GUI is pretty clear but open the administration tool, expand, right click......and so on.....too long sometime....clearly too long
It happens me every day : someone call me from another site/plant and ask me to make some changes. YES I know that we have some replication priority inside AD, it depends on the value that you are going to change.

Powershell --> Powerquick : move disabled users from a group to another

Hi Mates,
quick and useful : how many times you needed to have a clean group because to this specific group there was associated a software usage/number of licenses ?
It happened to me but my need was also to have a trace of the users that were members of this group.
So I started creating a group that hosts all disabled user account that TODAY are not using the software "attached" to the main group, but tomorrow I could need to know if a "returning" user had right to be a part of it......a sort of history.
