===== Domain Time Sync =====
To synchronise the time on a Windows PC with the domain, the ''net time'' command can be used in an admin console:
<code>net time \\stiftung.ifa /set /y 
oder
w32tm /resync
</code>
For a customisation in the GUI:

<CTRL>+R
datetime.cpl
</code>

===== Local User and Group Management on Windows 10/11 =====
To open Local Users and Groups window using lusrmgr.msc on Windows 10, you need to:\\
<code>Hit the Windows Key + R button combination on your keyboard.
Type in lusrmgr.msc and hit Enter.</code>
Alternatively, you can download an executable LUSRMGR.exe file to enable LUSRMGR.MSC in Windows 11 or 10. However, lusrmgr.msc is not available in Windows 10 Home. In this case, you can use control userpasswords2 in the Run box or Netplwiz to get to the passwords control. You can also download lusrmgr.exe to get a similar screen to that of the built-in lusrmgr tool.
