Windows 8

Νέο κενό ασφαλείας των Windows διευκολύνει την εύρεση του κωδικού σου
If you use Windows 7 or the newly released Windows 8, and like to password your account, this might be worrying news for you. It's been revealed that recent Windows OS' store password hints in such a way that makes it almost effortless for a remote user to decrypt them, potentially making it easy for them to guess your password.
According to an article at Ars Technica, Windows stores the password clues in the OS registry in a scrambled form which can worryingly be converted to a straightforward and readable format. This specific vulnerability would be useful for a remote hacker who has perhaps intercepted a cryptographic hash of the targetted computer in question.
The vulnerability was recently found by a SpiderLabs researcher named Jonathan Claudius, who posted an automated script and posted it to a website called Metasploit, which specialises in Penetration Testing Software. He says that "although this stuff looked a bit unreadable on the surface we can now see that it can clearly be decoded and could be used by tools that extract the information from the SAM."
To put this in perspective, the security flaw allows a hacker to gain access to the password hint that a user has set, only through initiating a different attack beforehand. The user's actual password is never decrypted, but this vulnerability does make it easier to guess for a remote user wanting to gain access. It is worrying however, that the information was apparently gained through an only eight-line Ruby script which decoded the text.
Microsoft have yet to comment on the discovery of this latest vulnerability to Windows account security.
Με μόλις 8 σειρών Ruby script καταφεραν και το σπάσανε! Νομίζω η τελική έκδοση των 8 δεν θα πρέπει να βγει αν δεν διευθετηθεί πρώτα! Crucial το κενό...

Να διαβάσετε το review του co-founder της MS για τα Windows 8 καθώς να δείτε και videos στο youtube με πραγματικούς χρήστες και όχι απλά να διαβάζετε τις "έγκυρες" σελίδες!

Bill Gates: “Windows 8 και Windows Phone 8 είναι κρίσιμης σημασίας για το μέλλον της Microsoft”
“Πρόκειται για απολύτως κρίσιμα προϊόντα, καθώς φέρνουν τη Microsoft στον κόσμο των φορητών συσκευών αφής και προκαλούν τον κόσμο να ζήσει την καλύτερη εμπειρία σε tablets και PCs. Η Microsoft συνδυάζει όλους τους διαφορετικούς τρόπους επικοινωνίας. Το Surface είναι η απάντηση στο ερώτημα ‘Μπορείς να έχεις ένα ακόμα καλύτερο tablet, αλλά με λειτουργίες που περιμένεις από ένα PC’”

Windows 7 to Windows 8: The system's biggest improvements
http://www.pcworld.com/article/2012834/windows-7-to-windows-8-the-systems-biggest-improvements.html
Free Xbox Music Pass now live for Windows 8 users
Microsoft sweetened the deal for all its potential Windows 8 users a few days ago when it announced that adopters of the new OS would get an unlimited free Xbox Music Pass. This is a good way for Microsoft to promote both its new OS and, perhaps more importantly, its new music service. The new Xbox Music rises from the ashes of the old Zune offering but brings much more - and it's consistent across the entire Microsoft ecosystem.
So if you're a Windows 8 user you might have noticed all of the updates for the first party apps that have been going on recently. One of them is for the Music app and if you haven't already updated you definitely should. Why? Well because this update brings the free music subscription that Microsoft mentioned a few days ago.
All you have to do after updating is to open the app, log in to your Microsoft account (in case it doesn't do it automatically) and start listening to music. There are no extra steps to go through which is really great - just open the app and go! The music you stream can also be added to your own music library of course, and you can also create smart playlists that incorporate both your own music and online offerings similar to what you're listening to. The only sign that you haven't actually bought these tracks is the cloud icon which you can see in the screenshot above. It actually resembles the Skydrive logo.
Being able to stream unlimited music out of the box is pretty awesome and should definitely sweeten the deal for those who are considering, but haven't decided yet on, a Windows 8 upgrade.
Xbox SmartGlass will "add to" rather than "distract from" Xbox 360 gaming
Free app coming 26th October alongside Windows 8
The free Xbox SmartGlass app will launch on 26th October alongside Windows 8 and Xbox Music, enabling touchscreen control of a wide range of functions on Xbox 360. It's part of a broad push towards cloud data sharing which will see Xbox become an umbrella brand for music, games and movies, seamlessly fed out to all the various media devices in your possession.
Speaking to CVG, Xbox Live product manager Pawan Bhardwaj discussed various gaming applications for SmartGlass. Among other things, you'll be able to view an interactive map on your tablet when driving around in Forza Horizon, and sneakily doctor Just Dance 4 playlists using the touchscreen while others are busy doing the Macarena.
"We really want to offer an enhanced experience for people playing games on Xbox," Bhardwaj told the site. "We don't want to distract from it, we want to add to it. It has to be a genuine accompaniment, so we're looking at games that will be enhanced and not hindered by second-screen tech." Here are seven other ways to make use of SmartGlass at launch.
Microsoft community pillar Major Nelson has more. "When the Xbox SmartGlass app launches on tablets, PCs and smartphones, it will include key foundational experiences for interacting with your Xbox 360, such as dashboard and app navigation and Internet Explorer control, like text input, scrolling and pinch and zoom.
"Additionally, you will get SmartGlass experiences with Xbox Video and Xbox Music starting this week. Xbox SmartGlass will be a free downloadable app that takes your Windows 8 tablets and PCs, Windows Phone 8, iOS and Android devices, and converts them into a smart second screen for the entertainment you are enjoying through your Xbox."

alex4444 έγραψε:να ρωτησω υπαρχει τροπος αναβαθμισης απο 7 σε 8? Σε τι κοστος?
Kαι βέβαια υπάρχει! Αν μάλιστα έχεις αγοράσει Windows ή PC τώρα πρόσφατα, μπορείς να πάρεις τα 8αρια με πολύ χαμηλό κόστος!
Οι τιμές που θα ισχύσουν στην Ελλαδα, θα βγούν από την MS Hellas!
