I just rebuilt my laptop last night, and after 10hrs of installs, I’m finally back to a ‘usable’ state.  One of the things I had forgotten about, that I take for granted was all of the registry hacks that I was used too. Basically, these hacks were ones I made so that additional options would show up when I either right-clicked on a folder or a file, in explorer.

Modify your registry at your own risk. If you hose your computer, I am not responsible.

Ok, so here are some of the keys I just added, and a brief explanation of what they do. They point to additional tools and utilities, so you may need to modify the paths to fit your system. I’ll list all of the keys at the end, so you can create a .reg file, and import them.

1.)This key allows you to right-click on a COM dll, and register it, just like you ran regsvr32 against it, from a command prompt.

[HKEY_CLASSES_ROOT\dllfile\shell\Register\command]
@="regsvr32 /s %1"

2) Same as above, except un-registers the dll.
[HKEY_CLASSES_ROOT\dllfile\shell\Unregister\command]
@="regsvr32 /u /s %1"

3)Register a COM .exe
[HKEY_CLASSES_ROOT\exefile\shell\Register\command]
@="regsvr32 /s %1"

4)Un-Register a COM .exe
 [HKEY_CLASSES_ROOT\exefile\shell\Unregister\command]
@="regsvr32 /u /s %1"

5)Right-click on a .NET assembly, and install in the GAC
[HKEY_CLASSES_ROOT\dllfile\shell\Register In GAC\command]
@="C:\\Program Files\\Microsoft.NET\\FrameworkSDK\\Bin\\gacutil /i %1"

6)And most importantly, right-click on a folder, and open it’s path in a  command prompt.
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\CMD Here\command]
@="cmd.exe /k pushd %L "

Here are all of the keys at once. Do you have any cool hacks! Add them below in the Comments section.
Cheers!
