Microsoft is investigating the so-called 'black screen of death' problem that was highlighted by security firm PrevX following its latest round of updates for Windows.
The PrevX blog discussed a problem it had seen from users of its software, where running some programs following the Windows 7 update would cause the computer to go to a black screen.
Microsoft has confirmed to TechRadar that it is indeed 'investigating the problem'.
Statement
"Microsoft is investigating reports that its latest release of security updates is resulting in system issues for some customers," said Microsoft in a statement.
"Based on our investigation so far we can say that we're not seeing this as an issue from our support organisation.
"The issues as described also do not match any known issues that have been documented in the security bulletins or knowledge base (KB) articles.
"As always, we encourage customers to review the security bulletin and related KB articles and test and deploy security updates. If customers do encounter an issue with security updates, we encourage them to contact our Customer Service and Support group for no-charge assistance.
"Customers can contact CSS using the information at http://support.microsoft.com/security."
The inevitable Black Screen of Death moniker obviously references the infamous Blue Screen of Death seen when Windows PCs went catastrophically wrong.
Lock down of registry keys
"…the cause of this recent crop of Black Screen appears to be a change in the Windows Operating Systems lock down of registry keys," says Dave Kennerly, the PrevX engineer that blogged about the problem.
"This change has the effect of invalidating several key registry entries if they are updated without consideration of the new ACL rules being applied. For reference the rule change does not appear to have been publicised adequately, if at all, with the recent Windows updates.
"In researching this issue we have identified at least 10 different scenarios which will trigger the same black screen conditions. These appear to have been around for years now. But our advice is try our tool first. If it works great. If it doesn't you are no worse off."

Yeah, good riddance, glad to see the back of you, you seem to have forgotten your little diatribe against Apple's products, in particular the iPhone some time ago.
Best of luck with your 'research' wan*er!

Spin it how you want, your a self confessed windows hater, you jumped the gun, making yourself look a fool in the process.
"As for your denial that you keep copies of all my previous posts, I think you might be lying"
I read the article in question with some amusement, remembered your, lets face it, memorable user name and did a bit of, whats called, research, to make sure I didn't jump the gun also. But if you haven't the intelligence to respond in a mature manner, I'll say goodbye, let you have the last word, and leave you to what will probably be the insult of the week. Or you may surprise us.

And your point is? That comment was still not laying blame at anyone in particular. Get a grip, Microsoft does issue 'dodgy' and bloated updates, that was indeed a general comment that you have conveniently taken out of context to further your pointless argument in defence of Microsoft.
As for your denial that you keep copies of all my previous posts, I think you might be lying? Are you at home now looking through them all, while simultaneously touching yourself in an inappropriate manner? Weirdo!

THAT, my friend, is laying the blame. And don't try to tell us you were talking about updates in general, you jumped in feet first, like prevx.
Also, the Mac OS X has been hit a couple of times this year, by a couple of minor malware problems. If this trend takes off with the script kiddies, will you slate apple?

Forgive me if I'm wrong but I don't recall laying the blame at anybodies door with regards to the black screen problem, all that I stated was that I dislike Microsoft products, Windows OS and that I think they are a waste of time and money. I also feel that if Microsoft were doing their job properly, inexperienced users shouldn't have to deal with problems like this.
I am led to believe that the problem stems from malware infecting a proportion of users systems, why is this? Does Windows 7 not come with protection against this type of threat 'straight out of the box?'
However, whichever way you try to dress this issue up, it seems to me that Microsoft either directly or indirectly should be responsible and carry a proportion of the blame.

None of the above. I just happened to remember reading your contradictory post. But you still haven't got the point yet have you? Try and be neutral for a moment, read this

Your blinkered mind still hasn't grasped what the rest of the world already knows, has it? Prevx were WRONG, let me say it again, WRONG. They wrongly stated that it was two windows patches that were the problem, have since stated that the problem is associated with a piece of malware such as daonol, and have apologised to Microsoft for jumping to the WRONG conclusion.
By the way, here's a quote from one of your other posts.
"However, it always irks when people see an Apple article, get all angry and then steam on in, making the usual inaccurate and cliched statements, without, in most cases, having read the article in question anyway."
Substitute Microsoft for apple in that statement, and you've just described yourself. Well done.

15. I've used three different incarnations of Windows and to be honest I hate Microsoft and it's Windows operating systems. I find them annoyingly slow (a little like you lovlid) very unpredictable, they never do what I want them to do, when I want them to, and thats the reason why I switched to a different system, a sensible move in my book... simpleton? get a grip! I know my way around a computer very well but still feel that the vast majority of consumers using these windows systems are inexperienced and shouldn't have to be dealing with issues like this so early on into their user experience. As for apologising? Why? Surely Microsoft should be doing that?

Some people (prevx) mistakenly blamed microsoft and two windows patches outright for the problem, and have since apologised, but only after the world has gone on its usual rant against MS. Even this site has been slow in updating the story.

12. People should learn how to back their files up. That is the most important thing they should learn before they learn about anything else about the pc.
Inexperienced users can learn by simply searching on google or even windows help.
There are so many help resources out there that to say inexperienced consumers shouldn't be able to do it is codswollop.
It's a little embarrassing for microsoft for this problem but it can't be that huge a problem otherwise they would have known about it earlier. Instead some people blog about the problem and everyone thinks the world is screwed.
Microsoft has done a huge service with their software, increasing productivity and entertainment in the home and office by more than any other software developer in the last decade.

You seem to be missing the point. Microsoft is the devil!
Don't forget the fact that these operating systems and their dodgy updates are aimed at a lot of inexperienced home users who wouldn't have a clue about back-ups, formatting and re-installing, why for that matter should anybody have to do that with a brand new OS that should be working correctly anyway? It's wrong of you to try and blame consumers for not being experienced enough, your defence of Microsoft and it's s**t products carries no weight here.
I fail to see the relevance of bringing the Government into the equation but granted, the Government are also doing a s**t job, the phrase 'two peas in a pod' springs to mind!

8. Is anything in this consumer world of ours rally perfect? My brand new car doesn't like cold mornings, my new cooker keeps trying to light it's self when hot,my PS3 doesn't like WIFI all the time and my kettle dribbles more than a retard. They all cost a lot of money. Considering how complex a OS is I don't think Microsoft are doing a bad job. Any PC user worth their salt would have backed the whole thing up, formatted and reinstalled. Not a massive issue really.I wish all the (Microsoft is the Devil)band wagoners would find a new target like the government. Look what they get paid and how screwed up our countries are.

They said customers, not consumers. It is common and good practice for businesses to review updates before rolling them out to their whole organisation. Obviously it would be straight forward for individual home users to simply roll back an update after it has been installed if it causes problems.
