Hello Friends,

I have a nice collection of tips and tricks to make you life with computer & technology easy.

Do reply to keep this thread alive..

Thanks

Before playing with the regedit it would be good to have a back up of it. I remember that I had to format one pc after messing up the registry. To back up
1. Go to run
2. Type regedit
3. Go to file and choose export
4. In the export range section there are 2 radio buttons which say all and selected branch. Choose whichever U think is appropriate (the names are self-explanatory I think)
5. Give the .reg file a file name and Save it in the location that U want.
After playin with the registry if sth happens U can restore the .reg file U just saved by double clicking on it.

Thanks sami and whiz. Speaking of registries ...
For IT guys,
When malicious software infects a pc, it almost always infects the registry. This may sometimes prevent you from logging into the PC and fixing the problem itself. Fortunately, there are ways to access the registry without logging into the system.
Option A - just take the harddisk to another PC and load the registry of the infected machine on the clean one.
Option B - boot from a live XP cd on the infected machine and load the registry from the live system.
I am sure there are more options that I am not aware of.
I have tested this techniques only with Windows XP. But I feel that they can also work on Win2k and Win2k3

To load the registry, you need to know where the registry files are stored. These files are known as "hives". The registry hives for HKEY_LOCAL_MACHINE (HKLM) are stored in
C:\windows\system32\config
(Assuming windows is installed in C:\windows)
The files are system, software, sam, and security (notice, no filename extensions).
So system refers to HKLM\System and so on. The ones we need mainly are Software and System.

The registry hives for HKEY_USERS are stored in the individual users' "Documents and Settings" folders with the name ntuser.dat.

Now, follow these steps to load the hives onto the registry of the uninfected machine (Option A) or live cd (Option B).

1. start regedit (Start>Run>regedit) - this may be slightly different on the live cds
2. click on HKEY_LOCAL_MACHINE
3. click on the menu File > Load Hive
4. Browse to the system32\config folder of the infected machine and load the hive you want (say, software)
5. When prompted, give the key a name different from those under HKLM (say, SW)
6. Now the infected machines HKLM\Software is accessible under HKLM/SW
7. Hack all you want and fix the problem

You can get live XP cds online (or i can burn one for you ). The one I use is known as MiniPE. There are also others known as BartPE, Ultimate Boot CD (UBCD), and Hiren's Boot CD. I will probably post another tip on fixing the problems themselves.
