What exactly does KB2952664 do?

Mike, have you never installed a fix from Microsoft, only to find that the fix had a problem and resulted in a subsequent crash or blue screen .... causing you to waste time figuring out how to remove the errant fix?

Yes to the first part when I have installed a fix which pretty much matches the problem encountered. But as it says on any Microsoft Fix page, unless the problem exactly fits what the fix is set to resolve, it shouldn't be used. So, we give it a go anyway.. whoops..

System Restore is reliable and fast in Windows 8, one of the features which Windows 7 users may appreciate having, so little is lost..

KB2592664 isn't a fix per se. It is an update and may just make the upgrade process quicker or add an extra line of instruction to make something clearer. Does it really matter? No, it does not..

I do know this. I encourage my local clients to install all Microsoft updates (including KB2592664) other than for hardware, and I do it for the three computers here that run Windows 7, and so far, none of us have experienced any problems which can be accredited to Microsoft updates..

I used the term "fix" in my last response, when I really meant "update" ... sorry for any confusion I may have caused.

You are very fortunate to not have experienced any problems that were accredited to Microsoft updates.

I realize that you stated "other than for hardware" ... but consider the update KB2862330. This was a security update that came out as part of MS13-081 and would have been automatically installed by anyone who had their Windows Update setting on Automatic. The description in MS13-081 does not mention hardware, but says this: "The security update addresses these vulnerabilities by correcting the way that Windows handles specially crafted OpenType Font files and specially crafted TrueType Font (TTF) files, and by correcting the way that Windows handles objects in memory." Many people who installed this update subsequently experienced a blue screen.

Below is an excerpt from Microsoft's description of known issues with KB2862330. While not everyone who installed KB2862330 experienced the known problems described below, many did .... my point being that someone with Windows Update set to automatic could end up installing an update that subsequently caused a blue screen ... so before I install the monthly updates, I prefer to wait a few weeks (except for updates that address zero-day issues) and do some research to see if any of the monthly updates are known to be causing problems after being installed.

I have used System Restore on my Windows 7 computer, but I find that mitigating a problem like the one shown below is seldom as simple as going back to the previous Restore Point ... I'd rather do my due diligence up front and avoid problems like this:

[excerpted from KB2862330]

Known issues with this security update

Symptoms

After you install this security update on a computer that is running Windows 7 SP1 or Windows Server 2008 R2 SP1, you may receive a D1 or 100000D1 stop error message that resembles the following:

*** STOP: 0x000000D1(parameter1, parameter2, parameter3, parameter4)

DRIVER_IRQL_NOT_LESS_OR_EQUAL

Cause

The installation of security update 2862330 should update all the drivers for the USB 2.0 core stack. However, in some specific computer configurations, the Usbport.sys driver is not updated. After the USB 2.0 core stack is in a partly updated state, a D1 or 100000D1 Stop error may occur.

The stop error is observed in any of the following situations:

• When the computer is transitioning to or from a lower power state (Sleep or Hibernation)
• When a USB port resumes from "selective suspend" mode
• During the installation of the update itself

Hello,

Thank you

Ratandeep,

You did not read all of the posts in this thread. You did not even read the original post that started this thread.

You only read my last post (June 8, 2014), and even then .... you did not understand that it was off-topic.

In my post of June 8, 2014, I was having an off topic discussion with another person. In that off topic discussion, I stated this: "my point being that someone with Windows Update set to automatic could end up installing an update that subsequently caused a blue screen ... so before I install the monthly updates, I prefer to wait a few weeks (except for updates that address zero-day issues) and do some research to see if any of the monthly updates are known to be causing problems after being installed."

My off topic discussion was NOT about a blue screen or Stop Errors, my off topic discussion was about how leaving ones Windows Update settings on "automatic" and always installing every monthly fix (without doing any due diligence) can result in system crashes. I provided an example of one such update that caused a blue screen ... but the off-topic discussion (and the topic of this thread) is not about blue screens or Stop Errors.

The link you provided only pertained to a Stop Error ... and Stop Errors were not the original topic of this thread, nor were they the subject of my off-topic post.

My apologies for confusing you with the off-topic posts that I made .... you apparently did not take the time to read this entire thread and understand the issue being discussed.

The topic of this thread is update KB2952664.

I am requesting that you read this entire thread, and then answer these about the topic of this thread. Microsoft has described KB2952664 as follows: "This update helps Microsoft make improvements to the current operating system in order to ease the upgrade experience to the latest version of Windows."

This description is very vague.

Please answer these questions about update KB2952664:

1. Exactly what is wrong with the current upgrade experience that warrants a fix to ease the upgrade experience?
2. In what ways does KB2952664 improve the process of upgrading to Windows 8.x??
3. What impact/consequences would one experience by initiating an upgrade to Windows 8.x without previously installing KB2952664?

I can tell you what i think it did to my pc although i am, not 100& my pc user score was 7.1 for my processor and after i installed this it was 4.9?? i uninstalled it and now its back to 7.1 could this be a ploy to make your computer seem old so you upgrade? im not sure but one thing i do no is i wont be putting it on my computer.
