When I saw the "Blue Screen", not sure which sub-forum to post on.

I had just installed Bitdefender Internet Security 2016 (aka. BIS-2016)
- to replace BIS-2015 -- BIS-2016 required all other BD products to be removed/uninstalled
- which I did with the official BD uninstaller_2016

Every year AV renewals always cause problems ...

On another machine (64bit Win7 PRO) new BD has sabotaged "OpenWith" assignments and locked opening TXT files to Notepad.
Brink's REG file solutions Restore_Open_With.reg and Default_TXT.reg did not resolve the issue
The only way I could change the file-association for .TXT was with File Type Manager by Nirsoft
-----
This 32bit Win-7 Home Premium laptop was screwed up by Kaspersky install in March last year and I have not had email on this machine ever since, despite clean re-installs (of mail client) and trialing other mail clients.
-----
So my faith in AVs is very strained to say the least. ​

End of rant

Since the alert on this machine everything is operating fine, and the temptation to-fix is strong... but now it ain't broken.

From the above "results" can anybody interpret what the problem might have been ?

------------
ADDEND:
Last year I screwed up the TXT and VBS file associations and Brink's .REG files rectified my screw-up.
Thanks Shaun ​

You may have not had a blue screen of death, but technically you did have a crash, it just wasn't bad enough to lock up your machine.

The sub-forum would have been: BSOD Help and Support In any event you would be asked to run the utility: http://www.sevenforums.com/bsod-help-support/96879-blue-screen-death-bsod-posting-instructions.html, and post the results.

As to your code revealing anything; The line BCCode: 1000004a indicates a memory management problem, I'm not sure what the other four arguments refer to.

• STOP 0x0000001A: MEMORY_MANAGEMENT

• Bug Check 0x1A: MEMORY_MANAGEMENT

If you wanted to move this thread to the BSOD forum for better visibility go to the

in the upper right corner and kindly ask one of the Mods if they would move it over to there.
