I just installed Soluto and found that "Microsoft .NET Framework 4 Extended" is taking 177 seconds to boot. Why does it take so long, and is there any way of speeding this up?

It turns out that .NET Framework 4 Extended includes an app called PresentationFontCache.exe. This was causing the slow boot and also using a lot of my CPU. I found a fix here - just delete the Font*.dat files from C:\Windows\ServiceProfiles\LocalService\AppData\Local.

1Was this the first reboot? If so, it was probably NGEN'ng the assemblies still. – None – 2011-06-14T09:24:01.450
The .NET Framework 4 is just a framework, it doesn't really do anything to "boot" (unless it was the reboot after installation as @leppie suggested). Are you sure this application isn't mistaking it for something built using the Framework? – vcsjones – 2011-06-14T09:25:05.640
@vcsjones: well the OP states he installed some app called Soluto. – None – 2011-06-14T09:26:43.103
1@leppie: Soluto is a boot benchmarking tool and I am just wondering if it is getting confused about something. – vcsjones – 2011-06-14T09:30:42.390
Not the first reboot, and yes it's entirely possible that Soluto's reporting incorrectly. I was just wondering if anyone else was seeing a similar problem. – parsley72 – 2011-06-14T10:17:20.803
