Hello Everyone,

In My Organization We Have Recently Implemented IT Infrastructure To Windows Server 2012 R2 and

Client Site Windows 8 Pro. We want to Upgrade All Client's From Windows 8 Pro to Windows 8.1 Pro.

I Can not Download 8.1 on all Client's and Upgrade As It Will Utilize More Bandwidth At Time.

Request You To Please Help Me How Do I Upgrade Multiple Windows 8 Pro To 8.1 Without Downloading On Every Client.

Please let me know Even if there is any tool or service from where i can upgrade my client's on single time.

Thanks & Regards,

Suraj Dudhane

Hi,

You may need to know the following when you upgrade to windows 8.1 enterprise:

Upgrading from Windows 8 Enterprise to Windows 8.1 Enterprise:

• Download your Windows 8.1 Enterprise media from the Volume Licensing Service Center (VLSC). Please note that Windows 8.1 Enterprise cannot be updated from the Windows Store; it can only updated using media obtained from the VLSC. Use this media to either:
• Perform an in-place update of existing Windows 8 Enterprise installations.
• Refresh existing computers using MDT 2013 or System Center 2012 R2 Configuration Manager*, or burn the media to a DVD or copy to a USB key for simple installation.
