Windows 7: HomeGroup not working, broken Networks/Sharing Console

Windows 7 Home Premium
HomeGroup not working, broken Networks/Sharing Console

I plagiarized the following from "Vista giving you a Server Execution Failed? - Page 2 - Networking - Xoxide Forum Network" which was an old post for Vista, but it worked perfectly for the broken HomeGroup problem in Windows 7. Apparently, something corrupts permissions and ownerships of some vital keys in the registry, which causes HomeGroup to stick it's head in the dirt. It's bit scary to watch some of this run, but just cover your eyes. It works. I was at the point of reloading Windows 7, but talked myself out of it at the last minute with some more searching. I'd also noticed that the network map was not displaying properly in the Networks and Sharing window, so I decided to search for "no network map onNetwork and Sharing center" in Bing, and voila, the link above showed up. I'm still not exactly sure what was broken, but another symptom was that I noticed that it was no longer complaining about having no active AV software or firewall. When I ran the third command line in step 3, both of those warnings popped up, which gave me pretty good indication something was getting better.

In addition to the steps below, I uninstalled McAfee Internet Security suite, turned off Windows Defender, and turned off Windows Firewall (I'm hiding behind TWO routers, so don't worry too much about security while I'm fixing things.)

1. Back up the registry. (DUH! You're about to overhaul the permissions)

2.Download and install SubinACL from

Download: SubInACL (SubInACL.exe) - Microsoft Download Center - Download Details

3.As an administrator, run the following commands from a command prompt (switch to the install directory for SubinACL first. Default is "C:\Program Files\Windows Resource Kits\Tools\" for 32-bit, and "C:\Program Files (x86)\Windows Resource Kits\Tools\" for 64 bit):

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f /grant=system=f

The first two commands can take considerable time to complete, however each command can be run in a separate window to save time. But what's your hurry?

3. After completing all four of the above commands you have to reapply the default security template by running the following command:

secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose

4. Reboot.

My homegroup is back now, and I can go load my McAfee firewall and antivirus software.

Good luck
