About this tag
The Shuttle SG45H7 is a small form factor PC model discussed in the context of Windows 7 boot performance issues. A user with a Shuttle SG45H7 system (4GB RAM, Intel quad-core 2.33GHz) reported a significant increase in boot time to about 5 minutes after upgrading from Windows 7 beta 7000 to RC 7057. Analysis using xbootmgr showed that drivers such as CLASSPNP.SYS, partmgr.sys, and others were consuming excessive time during startup. This tag covers troubleshooting slow boot times on this specific hardware model, particularly with Windows 7 builds.

    Hi, I have just done a clean install with the new RC of windows 7. But the problem now is the boot time has increased a lot about 5 min. This was not the case with the first public beta (7000). I have done some xbootmgr performance logging and I will attach some screen shoots of my findings...
