Uptime

Find Uptime from System Info

NOTE

The below records the time system last registered a full boot up. If you have FastBoot enabled, it doesn’t reset. Task Manager shows you the ‘duration’ of your uptime from this date, not the actual duration - ie hibernation doesn’t stop this

Get Uptime from Command Prompt

systeminfo | find "System Boot Time"

Get Uptime from CIM via Powershell

Get-CimInstance -ClassName Win32_OperatingSystem | Select-Object LastBootUpTime

User Profile Management

Don't just delete folders from c:\users\

Deleting folders of old user profiles from c:\users is not wise. Why? If that user account ties to login again, the system registry will still expect their profile folder to be there. When it isn’t, it will have an error and load a temporary profile.

To cleanly remove old profiles from a machine run one of the following:

rem Run this from an administrative command prompt
rundll32.exe sysdm.cpl,EditUserProfiles
rem OR 
rem run the below from anywhere (it will prompt for admin rights)
c:\Windows\system32\SystemPropertiesAdvanced.exe

Then press “Settings” inside the “User Profiles” frame. Then delete the users from there.
