You will also need to edit the following registry entries, if present. Please read the warning about editing the registry.
Renaming the registry editor
- Using Windows explorer, browse to the Windows folder (usually C:\Windows or C:\Winnt) right-click Regedit.exe and make a copy of it.
- Rename the copy of Regedit.exe to Regedit.com.
- At the taskbar, click Start|Run. Type 'Regedit.com' and press Return. The registry editor opens.
Before you edit the registry, you should make a backup. On the 'Registry' menu, click 'Export Registry File'. In the 'Export range' panel, click 'All', then save your registry as Backup.
Locate the HKEY_LOCAL_MACHINE entries:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
and remove any reference to any file you deleted.
Each user has a registry area named HKEY_USERS\[code number indicating user]\. For each user locate the entry:
HKCU\[code number]\Software\Microsoft\Windows\CurrentVersion\Run\
and remove any reference to any file you deleted.
Close the registry editor.
- Check your administrator passwords and review network security.
- To renable DCOM you can edit the registry, but it's better to use Dcomcnfg.exe. See Microsoft article 825750 for details.
- The HKLM\SYSTEM\CurrentControlSet\Control\Lsa\restrictanonymous = "1" setting does not allow enumeration of SAM accounts and names. The default is "0". It can be changed in Local Security Policy. See Microsoft article 246261 for details.
