Thinking about the date when you reinstalled the last time your windows machine?  Pretty easy to find, if you know where to look.

Press Windows button + R, type CMD + [ENTER]

then type systeminfo (documented on technet) and hit the .

Scroll up and look for “Original Install Date” (or boot time, or …)

If you use CMD.exe, then just hit F7.  It will give you all previous commands as shown in the screenshot below.

Oh btw, because I almost forgot.  There is a easy command prompt to create a new file.

copy con filename.txt

Hit return, just type your text and and with CTRL + Z (and return). You will now have a file with the content you wanted.  Thanks to Scott Hanselman for reminding me!

Notepad is a stripped down of wordpad.  My guess.   Just see this screenshot and judge yourself!

Noticed the changes in the font size?

On the internet you can find tons of information about exporting a dhcp reservationlist (from Microsoft DHCP server).

Today, I tried to do that using NETSH.  Unfortunately i always received the following error:

The following command was not found: dhcp 

If you see this error, you should check if the DHCP is available.  To do this, enter the next command:

netsh show helper

If DHCP is not shown in the list, you can add it, by running the following command on your command prompt:

netsh add helper dhcpmon.dll

After you added the helper, you will be able to run all commands regarding the dhcp.  For example get the server reservation list:

netsh -r MyDhcpServernameOrIpAddress dhcp server dump 

Ever had problems with the restore tool?
