If you're running Windows 8.1 in your business, the chances are it's sitting alongside Windows 7 systems as well. Forrester analyst JP Gownder points out that this approach is likely to be messy if you don't also have an up-to-date System Center deployment.
In a blog post, Gownder says that interest in Windows 8.1 has been increasing in recent months. The tablet-centric nature of the original Windows 8 interface and the need to retrain staff meant that many businesses chose to stick with Windows 7 instead.
Gownder suggests that situation is gradually changing, but also points out that managing a mixed environment will be tricky if you don't also upgrade your server infrastructure:
In most cases, enterprises with an interest in Windows 8.1 devices are running hybrid environments -- adding Windows 8.1 tablets (for example) into a largely Windows 7 environment. This is best accomplished using System Center 2012 R2; prior editions don't offer full deployment capabilities, making them onerous for I&O personnel to manage.
