hope this helps somebody, I found out what the issue was. Also, this
would happen with *ALL* .msc files, services.msc, gpedit.msc,
diskmgmt.msc, etc.



It seems some virus, spyware or some other malware substituted this
Registry Key [HKEY_CLASSES_ROOT\MSCFile\Shell\Open\Command] from a
REG_EXPANDABLE_SZ type to a REG_SZ, hence the "Access is denied"
because that wouldn't allow to form a proper command.



The solution is to remove the Key and recreate it by importing the
following into the Registry:



Windows Registry Editor Version 5.00



[HKEY_CLASSES_ROOT\MSCFile\Shell\Open\Command]

@=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00 ,52,00,6f,00,6f,
00,74,00,25,\

00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00 ,32,00,5c,00,6d,
00,6d,00,\

63,00,2e,
00,65,00,78,00,65,00,20,00,22,00,25,00,31,00,22,00 ,20,00,25,00,2a,\

00,00,00

Hi,

Simple solution to this problem ("Access Denied" for most .msc files) is:
(Re-associate .msc files to be open by mmc.exe).
Steps are:
1. Go to System32 folder in windows explorer. (Example: C:\Windows\System32)
2. Locate file "Services.msc". Select the file. Then Right click it and in
context menu, select "Open With...". An Open with Dialog will open.
3. In Open With dialog, select Browse, and locate mmc.exe (Ex:
C:\Windows\System32\mmc.exe).
4. In Open with Dialog, you will now see "Microsoft Management Console"
selected.
5. Select the option "Always use the selected program". Click ok. And your
are done.
Now,
Run Services.msc (Start->Run->Services.msc), and it should launch the
services without the access denied error.

Please let me know if it doesn't work for you.

Regards,
Hemant
