Some downloads on the site are not safe. While it is not intentional on their part, still if you're unlucky, some "upgrade" has a chance to crash your computer forever (ok, until you reinstall Windows).
I own both PC and Mac, and I use Windows and Snow Leopard.
Bad experience with Microsoft software, sometime to work with PC become nightmare.
I wonder why Windows can't use RAM memories at full capacity, and why fragment all the time HDDs?
Microsoft makes better and better programs. I love Windows Vista and Windows 7, because they have good firewall and Windows Defender. Also, Microsoft took care about appearance of Vista nad Windows 7. I don't want to say Windows XP is bad, but I must say it has got poor firewall and IE 6. If you have got XP, I recommend you to download some better firewall (e.g. ZoneAlarm or Comodo) and then turn off Windows Firewall, Windows Defender (however, it's possible to install it only if you have got a legal copy of Windows) and, what is most important in my opinion, IE 7 or 8 (maybe it's better to install IE 8). They are more safer than IE 6, and also they have got phishing filter (IE 7) or Smart Screen filter (IE 8) which are very good, plus SmartScreen in IE 8 checks your downloads. Though this, it's a good idea to open Windows Update when you have some free time and check are there some fixes and patches for IE. If you want, you can even download some toolbars and add-ons on IEAddons. Ok, if you don't like IE, you can download Firefox , Opera or Google Chrome. They are also excellent.
Seit einiger Zeit gibt es auch Visual Studio Express zum kostenlosen Nutzen, das finde ich, wenn man Hobby-Programmierer oder ähnlich ist, ganz gut. Für einfache Anwendungen reicht es vollkommen, wenn man Anfänger ist.
Ansonsten gibt es doch noch hin-und-wieder nützliche Infos und Werkzeuge für Admins und Benutzer.
Ich selber rufe die Seite nur gelegentlich auf.
