Microsoft Hotfix rollup and updates to attack Slow Boot / Slow Logon in Windows 7 SP1–plus some other things to help out

I get asked pretty often in my day job to help people troubleshoot / analyze / attack slow boot and slow logon issues they face in their Windows client or Windows terminal services environments, whether they be physical machines or VDI instances.  I wanted to share a few of the very quick and easy plans of attack that I take when the client endpoints are Windows 7 SP1 or servers are 2008 R2 SP1.

1. Install the latest enterprise hotfix rollup for Windows 7 SP1 or Windows 2008 R2 SP1 on all of your endpoints involved in the boot or logon process – that includes DCs, file servers, infrastructure servers, virtualization hosts, etc:

Using xbootmgr to trace boot, shutdown, and reboot performance issues

Microsoft has created a toolset called the Windows Performance Toolkit, or WPT, to help developers and users visualize and troubleshoot performance issues.  One of the tools in this toolset is specifically designed to assist with capturing traces of boot, shutdown, or reboot cycles, and can provide insight into drivers, services, winlogon, explorer, disk and CPU utilization, and even help with seeing things like disk fragmentation and driver load order.

Installing the tools

Before gathering any data, you will first need to download the installation packages necessary to install the Windows Performance Toolkit on your Windows 7 machine.  The Windows Performance Toolkit is a part of the Windows 7 SDK, but you won’t need to install the entire SDK to get the WPT installation files if you follow this guide.  First, you need to download the Windows 7 SDK, which is a 500K web installer (click the “Install Now” link).  Once you start the installation, you only need to check the “Windows Performance Toolkit” checkbox under the “Redistributable Packages” section – uncheck EVERYTHING else:
