OIS Motivation
• Windows 7 pilot project was started at CERN in December 2009
• On 31st March 2010 Windows 7 support was officially started
So we want to share:
• Experience from the pilot phase• Our subsequent deployment plans

OIS Current Windows 7 status
• Already over 430 Windows 7 installations• Default OS for new desktop machines:
– 32-bit version of Windows 7• Very few support cases to helpdesk• CERN Windows 7 distribution tested on all HW
models for which Vista was previously available (currently 11 different models of laptops and 7 models of desktops – available at CERN from 2006 up to now)
• Windows 7 available for installation on all hardware (which satisfies min HW reqs)

CERN facts and figures
• 6000 managed Windows PCs (mostly XP)• Microsoft Extended Support for Windows XP
stops in April 2014• Importance of starting the migration to
Windows 7 early (big effort)• 3 months of Windows 7 availability resulted
in more installations than we saw during 4 years of Vista availability

Windows 7, Engineering and Controls
• A large number of engineering applications are supported at CERN: AutoCAD, Inventor, ANSYS, Mathcad, Matlab, Mathematica, Cadence, Altium, etc.
• All these applications were tested by IT-PES group and are now available for Windows 7 (32 & 64 bit).
• The only engineering product which is not yet supported by the supplier on Windows 7 is Catia/SmarTeam ( should be available in Q3 2010 ).
• PVSS is still not available for Windows 7

Hardware requirements
• For Windows 7 32-bit:
(*) Equal or less than for Vista
Microsoft CERN Recommendations (*)*)
Memory 1 GB 2 GB (**)
Disk Size 16 GB 60 GB (***)
CPU 1 GHz 2 GHz
(**) 1 GB memory is enough if Windows 7 is configured without the AERO user interface
(***) 60 GB disk space for typical set of CERN supported applications

Hardware requirements
• For Windows 7 64-bit:
Microsoft CERN Recommendations
Memory 2 GB 4 GB (*)
Disk Size 20 GB 60 GB
CPU 1 GHz 2 GHz
(*) Main motivation of installing a 64-bit OS is to support higher memory configurations

OIS CERN Roadmap• 2009Q4
– Validate core office applications on Windows 7– Validate most recent CERN standard PC models– Windows 7 installable over the network
• 2010Q1 – Validate remaining applications– Update documentation and training offers– Start Window 7 service (32- and 64-bit)– No new Windows Vista installations
• 2010Q2 – Windows 7 as default Windows version for new installations at
CERN on supported hardware • 2010Q3
– Phase out Windows Vista at CERN• 2010Q4
– Define roadmap for ending support of XP at CERN

OIS Summary
• Windows 7 deployment proceeds according to plan
• The user feedback is very positive• We get prepared to define roadmap for
ending support of XP at CERN
