Windows blue screen fix

I installed MIKTeX 2.9.5105 64 Bit on my Windows 8.1 64 Bit OS. Then I installed TeXStudio 2.7.0 as my favourite TeX Editor.
Starting up TeXStudio, it did not find my MIKTeX Installation and therefore refused to compile documents.

How-I-fixed-it:

I found some hints here:
http://tex.stackexchange.com/questions/71073/i-installed-texstudio-and-miktex-in-the-wrong-order-how-can-i-do-a-clean-instal

Close TeXStudio. In Windows Explorer navigate to: %APPDATA% exstudio (Alternatively you can navigate to C:UsersYOUR_WINDOWS_ACCOUNT_NAMEAppDataRoaming exstudio).

Delete texstudio.ini file.

Restart TeXStudio.

This fixed it for me.

I wanted to switch my contact management from OpenXChange/Outlook to Outlook.com/Outlook.  Im using Outlook 2013 (15.0.4615.1000) on Windows 8.


I followed the steps described here: http://support.microsoft.com/kb/2844991/en-us and copied all contacts from local Outlook folder to the contact folder of my outlook.com account.


I turned out, that the contacts were synced, but the birthday date for all of them was gone. Even manually entering the date in Outlook did not fix it.


How-I-fixed-it:
- Export all contacts to a csv-file from Outlook
- Manually import the contacts from the csv-file in outlook.com


Today my firefox 33 did not start any more. In task manager the process was shown, but with memory = 0 and CPU = 0. But the HDD usage of my computer went up to 100% and it was fully blocked for everything else. Waiting for a couple of minutI es did not change anything, also rebooting did not help

How-I-fixed-it:
Since Internet Explorer since worked on the computer, i went to https://www.mozilla.org/de/firefox/new/ and installed the latest version of the firefox browser. After this, firefox worked fine again.
