Have a burning Windows 8.1 question you want answered that wasn't addressed in our recent Windows 8.1 editorial? If so, Microsoft has you covered as they will be hosting an Ask Me Anything (AMA) session on Reddit today starting at 10:30 a.m. and running through 12 p.m. Pacific time.

Redmond announced the AMA session in a tweet published earlier this morning. The company promises that several engineers will be on hand to field questions about the incremental operating system update which just went live today at 7 a.m. Eastern time in the states.

The update includes a number of features that customers have been asking for ever since Windows 8 hit the market a year ago including improved search functionality, the return of the Start and the ability to boot directly into desktop mode. The latter addition will finally allow a PC to simply be a PC in Windows 8 and was one of the top complaints of the new OS.

Windows 8.1 is available as a free upgrade for everyone that is currently using Windows 8. It is possible to jump directly from Windows 7 to Windows 8.1 and even install 8.1 fresh on an empty hard drive or solid state drive but you'll have to pay for the opportunity. The standard version retails for $119 while Windows 8.1 Pro commands $199 - the same price Microsoft was already charging for Windows 8.
