Definitely that's had malware, then.

Rename the 3 attached files to have .reg extensions instead of .txt  extensions, copy them to the ill machine and import them into the registry.
Then reboot and see if those services start.

Possibly you'll need to replace their DLL files (i.e. they might be missing) on the ill machine with a copy from the healthy machine, too.

Sometimes you can find backup copies of the DLLs in the
BFE - Windows\winsxs\amd64_microsoft-windows-network-security_*
Firewall - Windows\winsxs\amd64_networking-mpssvc-svc_* and
Security Center - Windows\winsxs\amd64_microsoft-windows-securitycenter-core_*
subdirs... so using those copies would probably be better (the subdirs won't start with "amd64" if it's not 64-bit... you never really said what 'bitness' they are).

Microsoft Security Essentials still might not start after all that, but try to get those 3 services running, first. :-)

are they in the same workgroup

can the laptop ping the desktop

how is \\desktop done as that needs say local dns in a routers dns system to work

try instead of \\desktop        \\ip address of desktop

can you ping desktop from command mode

same homegroup, same workgroup.  Waiting for computers to be free and logon remotely and try recommendations.

It appears the major culprit is the desktop. Sharing turned off.   Go into network and sharing center.  On trhe advanced sharing, cannot set to share.  Change settings, log-off per instructions, log back on, sharing is stilll turned off.

I upgraded Win7 Home to Ultimate.  Still same issues, cannot share printer. cannot turn on Windows Firewall.  It is strange that on the other computer on the network can access shared folders on other computer but again cannot access the printer or share the printer on the network.

> cannot turn on Windows Firewall

That's a malware/virus symptom.

Click Start/Orb, type in services.msc
click the one that appears at the top, under Programs (1)

Near the top of the Services window, see if the Base Filtering Engine service is running, and also scroll down near the bottom and see if the Security Center service is running.

Ran malwarebytes, spybot.  Found a couple of things, removed.  Still did not correct issue of turning on Windows firewall or allow me to turn on file sharing, etc.

There is no firewall listed in service, nor is there Base filtering or security center?
