As a result, IT security vendor Prevx has withdrawn its original blog posting blaming security patches for the black screen issue - which caused a flurry of reports on the subject - and apologised for any confusion.
The big question, however, is - what causes the black screen that has plagued users of Windows this last few weeks?
As reported previously by Infosecurity, users have reported their operating systems booting up normally, but when they log in the computer screen turns completely black.
Some users have also reported their machines running through a constant reboot sequence.
But Windows 7 isn't the only operating system affected, with Windows XP and NT users also reporting the black screen. And Microsoft has denied its security update has caused the glitch to occur.
"We've received questions about public reports that customers might be experiencing system issues with the November Security Updates (which some are referring to as "Black Screen" issues)", Microsoft said in a statement.
"We've investigated these reports and found that our November security updates are not making changes to the system that these reports say are responsible for these issues."
Several security firms - as well as Prevx - have released fixes for the black screen glitch, which are available online.
Unconfirmed reports suggest that the black screens may be due to malware, but with so many users reporting the problem on IT forums, it remains to be see which malware caused the problem.
Security concerns cause delayed software updates
Symantec, meanwhile, has revealed that over a third of European businesses delay desktop software upgrades citing security concerns as a major barrier.
In fact, the IT security vendor said, worries over hackers targeting newer desktop software to find vulnerabilities were highlighted as a major concern for more than a third (35%) of European businesses when considering upgrades.
The survey, which questioned 1400 IT decision-makers in the UK, France, Germany and Italy, highlighted that security concerns are being driven by media coverage of new software launches.
Almost two thirds of all European businesses (62%) admitted that negative press coverage played a role in influencing their decisions to upgrade.
Robert Mol, Symantec's principal product marketing manager for EMEA, said that the main finding from this research is that European businesses are nervous about making the move to new versions of software.
"It is interesting to see the cultural differences in where these concerns lie and how far it will delay their investment. A quarter of European businesses (27%) stated they will hold off on upgrading for at least another 12 months", he said.
"However, German companies are feeling more optimistic, with fewer than one in five (19%) planning to hold off investment."
