    Critical Updates (Home)

    Today I installed critical updates #823980, #821557, and #819696. The first 2 show in my add/remove, the 3rd. #819696 does not. Rechecked with updates and it says all 3 have been installed. Just wanted to check with you guys here to see If this one just doesn't show in add/remove for whatever reason. I want to make real sure this one is installed. <img src=/S/grin.gif border=0 alt=grin width=15 height=15>
    Thanks for your time.

    Victoria--

    I'm not sure why some hotfixes don't show up in Add-Remove. But I believe without exception they have to register in the Registry. Try going here:

    Hive: HKEY_LOCAL_MACHINE
    Key: SOFTWAREMicrosoftWindows NTCurrentVersionHotfix


    HKEY_LOCAL_MACHINESOFTWAREMicrosoftUpdates

    There will be a subkey for each hotfix that has been applied. This registry tip applies to NT, W2K and

    Windows XP Patch: Qfecheck.exe Verifies the Installation of Windows XP Hotfixes

    Hotfix Check Tools

    If you can't verify it still, let me know.

    From MSKB 819696:

    You must be logged on as an administrator to install DirectX 9.0b or the security patch.
    ( ... )
    To verify that the DirectX 9.0a security patch is installed on your computer, confirm that the following registry key is present and that it has a value of 1:
    HKEY_LOCAL_MACHINESOFTWAREMicrosoftUpdatesDirectXd x819696IsInstalled

    Re: Critical Updates (Home)

    Thanks.

    So in addition to the other registry keys/hives for Hotfixes/Updates if you had Direct X 9(a) in, and you put in the hotfix of course, you could just put "dxdiag" in run to see you were updated with the patch, or from the KB on the MIDI buffer overun correction built into the Direct X9([img]/forums/images/smilies/cool.gif[/img] patch you could check the value 4.09.00.0902:
    and the key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftDirectXVersion.


    If you had any Direct Version prior to 9 (a) you would just download Direct X 9, and if you had 9 (a) as you pointed out the other day, you could do it with the patch. But either way you do it, you'll get 9 ([img]/forums/images/smilies/cool.gif[/img] because I have tried it both ways with 9 (a) in.

    Re: Critical Updates (Home)

    You know, Victoria, I didn't look up what the patch was for. But Kaplinb has reminded me now that it's for the recent buffer overflow flaw in MIDI within Direct X so besides the registry keys for Hotfixes/Updates above, since this is both a security patch for part of Direct X and an update to Direct X 9([img]/forums/images/smilies/cool.gif[/img] if you have 9(a), then all you have to do to verify it's installation is to go to the run box and type in "dxdiag" and you'll see that you've updated from 9 (a) to 9)[img]/forums/images/smilies/cool.gif[/img] with the security patch as Kaplinb reminded me in Lounge: Windows: Direct X 9([img]/forums/images/smilies/cool.gif[/img] Out 24 July '03.

    I believe the bottom line is this: In addition to checking the above registry keys, you have two simple ways also to verify that you got in this patch which in simple words (that I have a chance to understand) corrects a Direct X vulnerablity that has to do with files for MIDI music playing and will give you Direct X 9([img]/forums/images/smilies/cool.gif[/img].

    Two additional ways to verify it's in since it's a Direct X patch/update:

    1) At the run box type in "dxdiag" and look at the version of Direct X on the box. It should be 9([img]/forums/images/smilies/cool.gif[/img].
    2) In addition to the reg keys/hive I pointed out above: From the KB 81986:

    Confirm that the following registry key is installed:

    HKEY_LOCAL_MACHINESOFTWAREMicrosoftDirectXVersion

    and that the value is 4.09.00.0902:

    Re: Critical Updates (Home)

    Thanks everyone for the help. Guess what..All I needed to do was run Belarc. <img src=/S/bingo.gif border=0 alt=bingo width=15 height=22> It listed it. Totally forgot about all the things it can do. <img src=/S/clapping.gif border=0 alt=clapping width=19 height=23> . See my attachment.
    I wanted to ask one other quick question. Its not on the same topic, so if you feel I should start a new thread I will <img src=/S/smile.gif border=0 alt=smile width=15 height=15> . If, I have a power interuption that gets past my surge protector, (should get a UPS, but here in Canada they do not come cheap !!!) Should I run a chkdsk immediately after?? Had some bad power problems for a few days about a month ago and whether this messed up my computer or something else entirely, for whatever reason, I had to do a restore to factory and lost everything (so sad).
    Thats it for now..
    Want again to thank you all for the help today. You guys are the best. <img src=/S/bravo.gif border=0 alt=bravo width=16 height=30>

    Re: Critical Updates (Home)

    Victoria--

    Thanks for the followup. Very resourceful! I clean forgot all about Belarc, and an even neater and more extensive type of free app that everyone should have called AIDA 32--you want the Enterprise EXE on the right (they have so many choices--it will work best even on a home/small business desktop--the zip doesn't always open up once it's downloaded) which is free and great and you'll see what I mean if you download it--these screenshots show what it does.

    2) I don't know the exact answer that would definitively connect your power-out or surge to needing chkdsk,but look at it this way--running chkdsk every once in a while is good maintainance. I can't define every once in a while, because as threads past have emphasized, that depends on what's going on with your disk. For what it's worth, I'd run Chkdsk/R the most complete from the Recovery Console--the most effective powerful way to run it. See Post 277452 this thread on Chkdsk. But it's not going to hurt. As to UPS--Tech TV has done whole shows reviewing them well. Should I Buy a UPS--Reviews--see the nice related links under "Related Articles" at the bottom and you'll get to be expert--if the right surge comes along, it can blow through anything--but you still of course should protect and odds are the UPS system you end up with will.

    3) Now you know how to get a tool that can spit out your hotfixes from the command line or go to the registry keys that will list them. I'm sure that somewhere there are apps that do that specifically, but using Belarc is a nice idea/tip.

    Re: Critical Updates (Home)

    Chkdsk or if your Flavor Has It Scan Disk After Power Interruption--Yes Run it!! "These power searges can wreak havoc on a hard disk"--Microsoft Press Insider Power Techniques Windows XP p. 264; and Run Defrag on All Drives As Well!

    None of the articles in a search give you the why and I like the why, but they all recommend running it with comments like "these power searges can wreak havoc on a hard disk." They don't tell you the anatomy and phisiology of how such havoc is wreaked, however. There is a lot of debate on which chkdsk to run, and some of it's been in the lounge, but the concensus of Tech Support at Exec Soft (Diskeeper) is to run chkdsk/r and run it from the Recovery Console-- I'm a fan of the RC because it has solved problems including dirty bit for myself and others that running gui chkdsk or dos prompt did not--and any source including the Windows XP Resource Kit will tell you that chkdsk/r "implies" chkdsk/f which means includes it.

    Also--these articles on recovering from power surges all recommend running a defrag and why not?--I manually defrag every other night and to me it makes a big difference and only takes a couple minutes with Diskeeper, 30% free space and I get a performance hit from doing it.

    Re: Critical Updates (Home)

    One last compelling reason to get a good UPS/BPS besides the disk, Victoria is that most people don't know that spikes can damage a computer chip down to the quantum level. The damage can be cumulative and incremental at even 10,000 times the voltage (5V) that a chip uses and one day a small spike can be the straw that breaks the camel's back.

    Re: Critical Updates (Home)

    What on earth is the "quantum level" in respect to a computer chip?

    FWIW, 1.1 times the rated voltage of a chip can destroy it, let alone 10,000 the rated voltage (which is not necessarily 5V).

    And what on earth has this got to do with the original question?

    Thank you so very much for all the information. Your research is appreciated. As I thought, a chkdsk should be done, when there is a power interuption. Perhaps it would have saved me from having to restore. But, as I said previously, it could have been something else entirely that messed up my computer. I will check out all of the links that you have so kindly supplied.

    One helpful resource is Drive Savers and they allude to impact of power surges and worse spikes on hard drives Power Outage/Surge" when they say that

    [i]"Why? Extreme power fluctuations can damage electronic components and cause the drive

    __________________________________________________ _____________________________

    Taking your second question first: It has everything to do with one of Victoria's questions in the thread--not her original question and I'll put it up here for your convenience. If you count 6 posts down the thread to Post 278526, she asks: "I wanted to ask one other quick question. Its not on the same topic, so if you feel I should start a new thread I will . If, I have a power interuption that gets past my surge protector, (should get a UPS, but here in Canada they do not come cheap !!!) Should I run a chkdsk immediately after?? Had some bad power problems for a few days about a month ago and whether this messed up my computer or something else entirely, for whatever reason, I had to do a restore to factory and lost everything (so sad).
    Thats it for now.."

    __________________________________________________ _____________________________

    The more I see and read about power supplies, I think a significant amount of time, (no idea of how often) when computers go bad, the problems may be due to power surges and much worse spikes that might have been avoided by a good UPS. I knew that it's often said that you should run a chkdsk when you're recovering from or after you have had a surge or a spike, but I wasn't sure why.
    They happened to have a guy from Drive Savers on Call for Help: Prevent Extreme Data Disaster July 28, 2003 today. This show is available in Europe, and I think the UK as well and John Christopher alluded to this. One reason to chkdsk and to be concerned about power fluctuations is that they can damage even very small chips and electronic components and cause the drive's read/write heads to write erratically to the media surface and cause hard drive corruption.

    When I did a search for chkdks/power out I got link after link that said "yes--run it by all means" but none of them told me the anatomy and physiology of why and I've had a lot of years of having to look for that why when something doesn't work well or someone feels it isn't.

    In going for the "why" I pulled out O'Reilly's PC Hardware in a Nutshell, 2nd Edition, Chapter 27 "Backup Power Supplies" to get some help. The husband/wife team of authors made the point that I believe is true and important and a compelling reason to try to have an uninterruptable supply (I can appreciate costs up in Canada, the UK, and they are going up here for all kinds of reasons)--they make the point that surges and particularly spikes can cause undetectable (or if you prefer undetectible) damage that is cumulative and incremental.

    Most of the spikes are 50,000 volts are more and of very short duration--milliseconds and can be stopped by the surge protector component of a good BPS/UPS. Of course if the duration becomes seconds, and the voltage more, it can be high enough to be unstoppable (lightning). <img src=/S/cooked.gif border=0 alt=cooked width=50 height=46>

    The point they were trying to make and I passed on was that electrical damage to chips and hard drives can be minute, and symptom-wise invisible until it gets to be a big problem that stops the computer from working, so that if there is a surge or spike and you have no protection, just because you see no immediate problem, doesn't mean one isn't incubating over time. They said that invisible damage to chips can occur down to the "quantum level." Here they must be referring to tiny chips IBM, Toshiba, Sony Team on Tiny Technology or even tiny chips in quantum computing that could have tiny but significant damage--again I think they were going for the importance of damage that was small and hard to detect but could finally push a chip or computer over the brink. They said damage could leave a computer "teetering on the edge" and a tiny spike could push it over. I don't think they were talking about a quantum spike, but rather a quantum chip in a quantum computer.

    Re: Critical Updates (Home)

    Hi I am back again..Regarding hot fix #819696. It showed up in Belarc (I discovered after posting this Q.) But not in my add/remove which was the reason for this post originally. On another board, there was a question by someone about the fix and a screenshot was posted WITH this fix in their add/remove. Now I am ever so curious as to why it showed up in someone elses add/remove and not mine. My head is spinning <grin>..I am now totally confused. Hope someone has an answer for this. FYI I have Dx 9.0a.. I have also att. the screen shot of this other persons add/remove.
    Thanks

    Re: Critical Updates (Home)

    Don't know where in Ontario you live, Victoria, but if you have a Costco close by you can pick up an APC UPS for under CDN$70.00. If you don't consider this "cheap", consider this: how much would it cost you to replace your computer?

    Cheers,
