A very useful blog article about killing active sessions to a compromised Office 365 account:
Starting from Windows 10 Creators Fall Update, you can use VT escape sequences to colorize the output to console. You can use this to colorize columns in Format-Table, too.
A sample snippet, colorizing the output based on the contents of the "Status" field:
$somelist | FT FirstName,LastName,@{l="Status";e={
switch ($_.Status) {
"OK" {$color = 92; break}
"NOT OK" {$color = 91; break}
default {$color = 93}
}
"$e[${color}m$($_.Status)${e}[0m"
}}
A complete list of color codes can be found here: https://docs.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences
HP 1920 switches (and others of the same kind) have a CLI mode which is highly restricted. It is possible to unlock this, providing full access to the configuration of the switch through CLI.
Log on to the CLI (SSH or Telnet) with the admin user and the password (default: none).
Type and press Enter:
_cmdline-mode on All commands can be displayed and executed. Continue? [Y/N]
Press Y to confirm.
Please input password:
Enter the password. This is a firmware-set password and is not user-defined. Depending on the firmware, try one of these:
If successful, you can now run all commands.
You can use either esxcli or vicfg-hostops to enter/exit maintenance mode.
esxcli
vicfg-hostops
Note that you can use vicfg-hostops --operation info to check whether the host is finished with entering maintenance mode or is still busy.
PowerCLI
After connecting to the host or vCenter server:
You can easily test the availability of an NTP server by using ntpdate. This utility is a command line utility which performs a one-time time sync to the specified NTP server but it can also be used to query the time without setting it by using the -q parameter:
$ ntpdate -q 10.30.0.1 server 10.30.0.1, stratum 4, offset 0.001217, delay 0.04170 8 Jan 10:19:36 ntpdate[2376]: adjust time server 10.30.0.1 offset 0.001217 sec
For those looking for the default PIN for the bluetooth connection of a HP OfficeJet H470, it's 0 0 0 0.
Although it can be found in the manual somewhere, it's easily overlooked.
Sometimes, you need to temporarily start a service (such as SSH) to perform some maintenance task. PowerCLI can help you with this:
To start the SSH server on each host of a vCenter:
read moreGet-VMHost | Get-VMHostService | ? {$_.Key -eq "TSM-SSH"} | Start-VMHostService
To stop the SSH server:
Get-VMHost | Get-VMHostService | ? {$_.Key -eq "TSM-SSH"} | Stop-VMHostService -Confirm:$false
As always, you can make adjustments to the oneliner to select another service to start/stop, or further limit the selection of hosts to a cluster or a group of hosts (e.g. filtered by name).
For all you Belgians (Flemish) out there, a list of live-streams (MP3) for people who don't want to use the online player of VRT, or simply can't use the player (e.g. linux users?)
Simply load these up in your favourite player supporting MP3 streaming through HTTP (such as VLC Player).
Readers that have read this page before will notice all streaming URLs are gone. VRT has switched to another streaming provider, causing all streaming URLs to change. The new list can be found here:

For those that do not wish to use OneDrive and want it removed from the folder tree in Explorer, can do so by a simple registry change:
Open regedit and locate the key: HKEY_CLASSES_ROOT\CLSID\{018D5C66-4533-4307-9B53-224DE2ED1FE6}
Change the value of System.IsPinnedToNameSpaceTree to 0
When using 64-bit, repeat the process for the key: HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{018D5C66-4533-4307-9B53-224DE2ED1FE6}
Note that starting from Windows 10 Creator, you can also remove OneDrive by uninstalling it:
As found on Voip-info.org, a list of bandwidth consumption per codec.
It's worth mentioning that the table also indicates the total consumption including IP overhead. When making assumptions about bandwidth requirements, it is useful to take this overhead into account.
| Codec | BR | NEB |
|---|---|---|
| G.711 | 64 Kbps | 87.2 Kbps |
| G.729 | 8 Kbps | 31.2 Kbps |
| G.723.1 | 6.4 Kbps | 21.9 Kbps |
| G.723.1 | 5.3 Kbps | 20.8 Kbps |
| G.726 | 32 Kbps | 55.2 Kbps |
| G.726 | 24 Kbps | 47.2 Kbps |
| G.728 | 16 Kbps | 31.5 Kbps |
| iLBC | 15 Kbps | 27.7 Kbps |
You can easily verify whether an ADFS implementation is working by using a browser and trying to log on:
https://adfs.yourdomain.com/adfs/ls/IdpInitiatedSignon.aspx
Replace adfs.yourdomain.com accordingly.
Note that in 2016, this no longer works unless you re-enable this feature through Powershell:
Set-AdfsProperties -EnableIdpInitiatedSignonPage $true
