Sounds like advice for previous MS operating systems!
I gave up on Vista Ultimate two weeks ago, reformatted and went back to XP Pro and installed SP3.
THAT's how to speed up Vista!
All these MS suggestions date back to Windows 95/98 era.
Now, my homebuilt PC (2.667 ghz Core 2 Duo with 4 gigs DDR2, P35 Chipset, NV8600GT and all SATA II drives) seems like a real computer instead of a Windows 95 box on a PII.
In fact I built the dang pc to be at the high end of the "Vista Experience" range (5.4 out of 6).
Boot time on Vista was 60 seconds just to the login, now around 20 seconds (including all programs) w/ XP Pro.
Nag time with UAC on was infinite. Turned UAC & "Offender" off and then got an "automatic update" that fried folder permissions system wide (Mr. Gates, the Documents folder is MINE and I don't need your frikkin permission to open it!!)
My drives churned the whole time the PC was on. Tried all the suggestions made in your article and they did nothing to speed up operation or boot. Okay maybe turning off indexing helped a very little.
Windows update (on Vista) cannot be prevented from installing stuff you did not ask or give permission for. In fact, as long as you have a connection to the internet, it will use your internet connection before you have finished setting up the OS. Now that is scary.
Even worse was the continuous scanning of all files and folders for copyrighted material and the phoning home to Mother MS of what was found. (Too many outgoing packets on a clean install to be anything else)
Driver support sucks for last years hardware even with all updates and hotfixes applied. Intel chipset and SATA AHCI drivers overridden by Microsofts crud at every turn. Damn, I could have sworn I had a dual core processor! (Which I did, but Vista could not figure out at setup)
Driver & program protection is way too tough for it's own good! System refused to recognize AVG Free, Zone Alarm Free & Spybot S&D as allowable programs.
God forbid you should want to use Windows Explorer to look in any of your file folders. I still see "You do not have permission" burned into my retina's. I tried logging on as Admin with Ctrl + F1 to no avail, then found a reg file called "Take Ownership" and tried that which worked to some extent. Do I really need to "Run as Admin" when I AM the frikkin ADMIN?!?!
I should not need to jump through hoops to have "permission" to print documents or edit my printers settings (took 2 evenings to find which permissions needed fixed)
All in all, there were things I liked in Vista, particularly the installation and drive partitioning during setup, but the rest just sucked beyond belief.
The very last straw was trying to load Service Pack 1 for Office 2007 and getting the message that I did not have permission to access the required network resource whatever that meant.
FWIW, Office 2007 and Outlook 2007 works just fine in XP Pro. Programs just snap open
