How to boot from PXE on Windows 7 in Hyper-V

It’s not that difficult, but it can take some time to find out how to do this.  Everything you need to know about this is explained here:


“Eject OPEN … 4GB-Windows 7 …” when clicking on “Safely Remove Hardware and Eject Media”

With one of my old USB sticks (2GB Dane-Elec Z-Mate), something strange happened.

Each time when clicking on the “Safely Remove Hardware and Eject Media” (on Windows 7), it displayed “Eject Open … 4GB-Windows 7 …” (see below).


After searching on Google I found a solution:

In Windows Explorer go to C:\Users\USERNAME\AppData\Local\Microsoft\Device Metadata\dmrccache\en-US.
You should find the following folder there: \d42472c3-a173-455f-8fc5-640e344597b1\.
Delete this directory (folder) d42472c3-a173-455f-8fc5-640e344597b1 with the offending USB drive still attached to the computer.
Now use the “Safely Remove Hardware and Eject Media” and remove the offending USB Device.

Reinsert the offending USB Device and all it will be displayed normally.
Indeed, after doing the operation above, the USB stick would show up as below:

Different ways of finding Windows uptime

1) Using Event Viewer

Filter on Event ID 6005.

The date and time when the Event ID 6005, The Event log service was started, is logged is the time when the Windows system was started.


  • You can see all startup times
  • Can also be used on remote systems.

2) From command line

Go to Start, Run. Type Cmd (Enter). On the command prompt type: net stats srv

Look for the text: Statistics since … For example: Statistics since 18/09/2009 9:34:09, meaning the Windows system was started on 18/09/2009 at 9:34:09.

You can also use the FIND command to retrieve only the line containing the time when the machine started.

net stats srv | find /i “statistics since”

Upgrading from Vista to Windows 7 (RTM)

I just upgraded my Windows Vista Business 64-bit to Windows 7 Ultimate 64-bit. I made some screenshots of the upgrade. It took a long time (between 3 and 4 hours, on an HP  notebook with an Intel Core Duo CPU T8300 2.40 GHz with 4GB RAM), but besides from the time it took, it went more or less smooth. I only had to uninstall an unsupported McAfee VirusScan (and replace with another antivirus product); the rest were minor compatibility issues.

I downloaded the Technet DVD ISO file, requested a key, and burned the DVD. Then from within Vista started setup.exe.

Most of the time when you are already running Vista you won’t have that much compatibility problems, so I skipped the compatibility check, and clicked Install now.
