Enable AHCI support in Windows Vista/7/8

If you have installed Win7 on an existing PC, and suddenly find yourself needing or wishing to
take advantage if the enhanced performance from ACHI (over legacy IDE)... 

In regedit, go to HKLM:SYSTEM:CurrentControlSet:services\msahci

Click on Start, choose MODIFY, and set the value to zero.

Shutdown regedit, shutdown Windows, power cycle PC and go to your system BIOS setup
and enable your controllers AHCI support and save the config.

Boot into Windows, it will load an AHCI driver.  Reboot again and the machine will be
running in AHCI mode.

AOL webmail crashes with IE 11

For those of you still paying AOL to get email (why I don't know) and if you are having
issues where IE crashes as soon as you login to AOL Mail... where it says "IE has stopped responding"...  remove IE11 and go back to IE 8... it seems to be the only IE that works
with AOL Mail.

I had tried resetting IE back to factory, clearing caches and all that, updating Java, modifying compatibility settings, disabled helpers and plugins... all on a fresh install of Win7 Pro... nothing worked. I noticed on another machine that IE8 would bring up AOL successfully.

So, I removed the update that installed IE11, ran IE8.. and it worked... AOL Mail now
comes up without crashing.

Itunes crashes with R6027 Pure Virtual Function Call or Itunes has Stopped Working

I have had numerous issues with Itunes 64 bit 11.1.38 (and other previous versions) locking up and crashing upon start with "Itunes has stopped working" or "R6027 pure virtual function call".  I have researched the answers around the forums as well as having tried some extensive and repetitious troubleshooting myself and thought I'd list them here... in order of troubleshooting...

1. Install all Windows updates and reboot.  This seems to clear issues from time-to-time... I suspect Itunes expects the latest-and-greatest as far as Windows is concerned.. see if this clears your issue.

2. Remove the contents of your "Iphone photo cache" (or other related product)  directory...

3. Try editing the shortcut properties and configure the shortcut (for all users) to run as Administrator.

4. Try editing the shortcut and configure it to run in Compatibility Mode for Windows 7 (for all users).

5. Uninstall all Itunes and Apple products; reboot, remove their directories, remove lingering Itunes registry entries, reboot again, reinstall using "RUN AS ADMINISTRATOR" to install the Itunes executable. See if this allows Itunes to stabilize.  Please be sure to use the following guide from Apple as far as removing the apps and directories are concerned...

NOTE: If you are having issues with accessing ITunes STORE, try reinstalling the latest QuickTime player.

6. a.Try using MSCONFIG to locate a potential conflicting application or service using the following...


6. b. Remove the last recent software application(s) you may have installed... in my case removing GREENSHOT  stopped my Itunes from crashing on startup and it stabilized after driving me nuts for weeks.
