How to fix: Windows 7 loads default instead of user-modified profile wiping off all settings, files, email accounts, bookmarks

I repeatedly run into the “default user profile instead of my user settings” problem with Windows 7. Once in a while when I log in onto my user profile on my Win 7 computer, it logs into default user profile and all my settings in web browsers, office files and other software is gone! MS Outlook asks me to set up all the email accounts over again! My documents directory is empty, but all files still can be found in C:\\Users\myusername… So what is the problem and how to fix it quickly? Last time it happened I googled solution and quickly learned that this is pretty common problem for Windows 7, and the only fix is to edit Registry. Now as it happen again this morning I could not found exact instructions on the web again, so after frantic searching for solution (and finally fixing my PC), I decided to post it on my blog in IT tips section… 

One of the people posted in a forum, almost as an after-thought, all tucked away where, if you didn’t take the time to read thoroughly, you’d miss it:

“I solved my problem by going into the registry and delete the effected profile’s subfolder under:

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList”

Note: HKLM refers to “HKEY_LOCAL_MACHINE” in the registry.

Formatting Array Input Data File in RES2DINV: surface electrodes for any geometry

pseudosection for 2D resistivity surveys

Example of electrodes arrangement and measurement sequence that can be used for a 2-D electrical imaging survey is shown on the left. Many different multi-electrode systems have been developed over the past 15 years using different arrangements of the cables and measurement strategies (Loke, 2011). This program is designed to invert large data sets (with about 200 to 100000 data points) collected with a system with a large number of electrodes (about 25 to 16000 electrodes). The survey is usually carried out with a system where the electrodes are arranged along a line with a constant spacing between adjacent electrodes. However, the program can also handle data sets with a non-uniform electrode spacing. RES2DINV program can be used for surveys using the Wenner, pole-pole, dipole-dipole, pole-dipole, Wenner-Schlumberger, gradient and equatorial dipole-dipole (rectangular) arrays. In addition to these common arrays, the program even supports non-conventional arrays with an almost unlimited number of possible electrode configurations (Loke et al. 2010). You can process pseudo sections with up to 16000 electrode positions and 70000 data points at a single time on a computer with 4 gigabytes (GB) of RAM. Besides normal surveys carried out with the electrodes on the ground surface, the program also supports aquatic and cross-borehole surveys.
