NEW YORK (TheStreet) -- Microsoft's (MSFT) - Get Report highly publicized release date for the new Windows 10 was July 29. I have six PCs ready and waiting for my free upgrades to the new operating system. So far, nothing has happened.

Of those six personal computers (laptops, notebooks, a netbook and tablet), all are running a combination of Windows 7, 8 and 8.1, and two are testing the beta version of Windows 10. All have been officially registered and approved for the upgrade, but so far no upgrade.

What gives?

Plenty of other people besides me haven't received the upgrade. At the top of Microsoft's Community Q&A page, to answer more than 13,000 complaints so far is the post "Where is my upgrade? It's Coming!". The very brief answer is "With your reservation, you are in the queue for your upgrade. Watch for your notification to arrive in the coming days or weeks. At that point, you can upgrade immediately or pick a time that works for you."

Making the wait seem even longer, on Thursday morning I was witness to another computer that has already been upgraded to the Windows 10 release software. It's even cooler than the beta version I've been running.

Microsoft listened to all the user complaints about Windows 8 and 8.1, and has offered a delicately balanced compromise. Windows 10 brings back a lot of the familiar features of its beloved Windows 7 and has thankfully downplayed a number of the not-so-well-liked features of Windows 8. 

The best thing about the new Start menu is that it brings back one-click access to your favorite/most-used programs and destinations, and offers Windows 8's boxes interface in a much smaller setting. The silly "Charms" menu, which used to slide out from the right-hand side of the screen and get in the way, has been replaced by a new "Notifications Center" that keeps you informed of system messages and any housekeeping you might need to do.

Windows 10 also offers a new Web browser, known as Edge, which is amazingly fast. It's lean and mean compared with what Internet Explorer had become. It's not perfect, but should be able to keep pace with Google (GOOGL) - Get Report Chrome and the rest of the competition.

The other major Windows 10 improvement is the addition of Cortana, which is Microsoft's voice-activated assistant. If your computer's hardware can handle it, Cortana will add a new layer of human interface with your PC to help get things accomplished. Microsoft has also added a major level of compatibility for Xbox One and Xbox Live as well as a set of standard apps (such as an improved Mail program) and an overhauled Microsoft Store for all sorts of application and game downloads. 

Microsoft has done a better job adjusting the new operating system for use on tablets and tablet/keyboard portables. Aside from not having to navigate back and forth from a two screen system (even more painful in Windows 8/8.1's touchscreen mode), you should find that Windows 10 is much more tablet friendly. 

From what I've seen so far, Windows 10 is a huge improvement over the last two releases. But, if you're anything like me, you're waiting for the new version.

Just hang in there.
