Installing Windows from USB - The easy way

Microsoft has a tool which allows you to create a bootable* USB drive (or DVD, but dual-layer discs are not supported) for installing a copy of Windows. The tool is called: Windows USB/DVD Download Tool

The Windows USB/DVD Download tool allows you to create a copy of your Windows 7/8 ISO file on a USB flash drive or a DVD. To create a bootable DVD or USB flash drive, download the ISO file and then run the Windows 7 USB/DVD Download tool. Once this is done, you can install Windows 7 or Windows 8 directly from the USB flash drive or DVD. 

Wireless HotSpot using your laptop (Windows 7 and Windows 8)

I get to travel around and I have stayed in a number of hotels. One of the most important things for me is Internet access during my stay. I have been to hotels (major hotel chains) where the WiFi signal is so weak in the room that sometimes you need stand by the open door in order to send an email. That is not very convenient, so I needed a quick solution in such cases. By creating a hotspot using your laptop's Wireless adapter, you can have a very strong signal anywhere in the room to access the Internet from any other devices you may have with you (e.g. mobile phone).

I am assuming that your laptop has both an Ethernet port and a Wireless adapter. Before you start check Windows Updates to make sure you have all the latest security updates and the latest drivers for your Ethernet card and the Wireless adapter (consider rebooting if needed).

Reverse IP Lookup under Windows

Yes, dig is an amazing Linux tool, and yes, you can do reverse lookups by typing:
dig -x [IP Address]

However, if you need similar functionality under Windows, you can do:
nslookup [URL]

or for reverse lookups:

nslookup -type=PTR [IP Address]

ALL YOUR PICTURES "ARE" BELONGS TO US

Back in 2003, on a rainy night, an idea came to mind regarding the extraction of all the pictures from a host; ..and the title was inspired by the famous .."all your base are belong to us". [1]

I was looking at the thumbnail view of one of my folders and started wondering how does MS Windows® OS store information about thumbnails within each folder. Obviously that was the "thumbs.db" file which it was introduced with the release of W2K. (Note: Actually Win98 had the functionality of displaying thumbnails but you had to know the trick to enable this feature. In Windows Millennium the functionality was included but there was no thumb.db file).
