CTRL-ALT-DEL via UltraVNC not working in Windows 7/2008(R2)

By default, send CTRL-ALT-DEL does not work on windows 7/2008 at the login screen when using UltraVNC. This can be fixed by editing a group policy:

1) “Start menu” -> “Run…” – > gpedit.msc
2) Navigate to “Computer Configuration” -> “Administrative Templates” -> “Windows Components” -> “Windows Logon Options”
3) Double-click on the “Disable or enable software Secure Attention Sequence” parameter.
4) Check “Enable”, then select “Services” in the combobox.
5) Apply the modification

    Found that enabling Remote Desktop in Windows 7 systems and Windows 2008 servers allowed UltraVNC to work.
    Tested with severial versions of UltraVNC that did not work or did not work consistently.
    This fixed the Crtl+ALT+Del and other problems. Still researching why… Can any one else confirm this????

    Did not solve my problem on Win 7, 64-bit virtual machine. I edited the group policy per instructions. I also have remote desktop enabled and UAC turned on. All to no avail 🙁

    Run this from commandline:
    reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v SoftwareSASGeneration /t REG_DWORD /d 1 /f

    Worked for me on Windows 2008 R2.

  8. I love your blog.. very nice colors & theme. Did you
    design this website yourself or did you hire someone to
    do it for you? Plz answer back as I’m looking to construct my own blog and would like
    to know where u got this from. appreciate it

    When these appear, the negative content gets pushed
    back further and further, until it is so far back about the Google results list that nobody
    pays attention with it. Not only does Google’s robot ponder
    over it relevant, but humans do, too, and therefore are
    more likely to click for the ad. * Twitter isn’t just while using feature to assist users find
    additional information. The webpage features a slogan in support from the site that obviously inspired it:
    ‘When older brother stayed for older.
