BSOD Again: Microsoft was one of the first companies to release updates to them Meltdown and Specter vulnerabilities on all versions of Windows that still receive support. But as it turns out, at least two of these updates are more bad than good.
The error caused by the KB4056894 collective update in Windows 7. The known BSOD that reports the error is displayed: 0x000000c4.
Windows 7 users are already discussing this issue on TechNet, and some reportedly believe that the BSOD is caused by problems συμβατότητας με το εγκατεστημένο λογισμικό protectionfrom viruses. Microsoft on the other hand says that the Meltdown and Specter fixes are only sent to systems running a compatible antivirus.
However, there are also some Windows 7 users who report that they do not use any software security by third parties.
Some publications on Reddit and Forums Microsoft's tests show that it is a widespread issue and uninstalling the patch that causes the BSOD is the only one choice, although this means systems will remain vulnerable to Meltdown and Specter attacks.
To remove the update on a system showing BSOD, you should use the “Repair your computer” screen from startup (either by pressing the F8 key or the corresponding key depending on the manufacturer devices).
Open a Command Prompt window and run the following two commands one at a time:
dir d: dism /image:d:\ /remove-package /packagename:Package_for_RollupFix~31bf3856ad364e35~amd64~~7601.24002.1.4 /norestart
Φυσικά η Microsoft θα μπορούσε να κυκλοφορήσει κάποια ενημερωμένη έκδοση που διορθώνει το πρόβλημα στο αυριανό patch tuesday.

Dear George, I personally found that my computer running Win7pro x64 has done this update automatically, and I had not noticed until today. Essentially, the result I observe is, unlike in the past, a half-minute delay in the transition to the desktop. In the opening of Windows let's say. I have not finally decided whether all this is good or bad.
What do you think; Should I leave it like this?
If I tried to uninstall this update, would I have another malfunction?
Thank you, John.
Good evening John,
normally there will be no problem with uninstalling, except that your PC will be left unprotected, as long as it does not bother you, it would be good to leave it as it is. Besides, they have already mentioned that these patches will have performance issues, especially in older systems.
Whenever it is something you can probably avoid
Thanks a lot for your time.
The truth is that apart from this delay, I have not noticed any other impact.
My PC has good data, which is probably why. 250αρη SSD Samsung pro, i7 at 3,4, 8gb ram… ..
So I will be satisfied and safe with a simple delay in starting for half a minute more.
Good continuation, happy new year!
She is excellent
