I used "ProcessMonitor" to find out what the heck explorer.exe was doing.
»technet.microsoft.com/de-de/sysi···645.aspx

It turned out, that explorer.exe made millions of reads on a TrueCrypt encrypted file named "private.dat", that I placed on my desktop! I starded a shell with cmd.exe, shot down explorer.exe with the task manager and renamed the file to "private.cr".
When I restarted explorer.exe it was at 0% CPU :D!]]> http://www.dslreports.com/forum/Re-WIN7-explorerexe-high-cpu-usage-22732370 Sun, 19 Jul 2009 09:17:46 EDT Re: [WIN7] explorer.exe high cpu usage http://www.dslreports.com/forum/Re-WIN7-explorerexe-high-cpu-usage-22536974

I had a problem awhile ago with IE7 slowing to a crawl replicating itself with multiple instances that remained even after I closed all IE windows. I had to manually kill them off from the task manager to restore speed.

Not sure what caused that, but later updates to IE7 or java or something seems to have resolved that.

I currently have IE 7.0.5730.11 in XP Home. Updates tried to install IE 8, but I cancelled that because it did not work in a Vista PC at work (could not print and Help, About was blank) and I think it is more difficult/impossible to uninstall from XP with service packs.]]> http://www.dslreports.com/forum/Re-WIN7-explorerexe-high-cpu-usage-22536844 Thu, 11 Jun 2009 19:59:43 EDT Re: [WIN7] explorer.exe high cpu usage http://www.dslreports.com/forum/Re-WIN7-explorerexe-high-cpu-usage-22536331 http://www.dslreports.com/forum/Re-WIN7-explorerexe-high-cpu-usage-22536331 Thu, 11 Jun 2009 18:17:36 EDT [WIN7] explorer.exe high cpu usage http://www.dslreports.com/forum/WIN7-explorerexe-high-cpu-usage-22536234 http://www.dslreports.com/forum/WIN7-explorerexe-high-cpu-usage-22536234 Thu, 11 Jun 2009 18:01:14 EDT
