Skype is doing that from start. But for MSN, if you login from another device, you would be forced to logout from the first device.

Now MSN live supports login from multiple devices. This is a very nice feature as many people have PC/Laptop/Smart Phones. The chat can be seen in more than one place and thus the chatting history can be saved into multiple locations (unless you exit MSN from one of your devices)

Not all software that works on Windows XP/Vista will work on Windows 7. Mounting ISO files can be difficult if you’ve been using Daemon Tools to do it so far. There is an updated version of Daemon tool available but it is not official. You need to search bittorrent for with.

Currently we have found two utilities that support windows 7.

There are many reports on the “Cannot copy files required for installation error” (with error code 0x80070017). There are many reasons:

1. When you burn the ISO image to a DVD, you need to choose the lowest speed and verify it after burn.

2. Do a memory test. You can get a tool from

Any errors reported need to be ironed out.

3. Reload your BIOS settings to default and make sure you are not aggresive to overclock your system.
Compared to Linux or XP, Windows 7 is very poor in terms of overclocking. We had a over-locked system running Linux for a couple of years but Windows 7 freezes from time to time so we have to undone the overclocking.

You can also disable things you do not need (such as onbard wifi for a desktop, firewire etc..)
