1. How can I check what Service Pack has been installed in an NT machine ?
Control panel - system only told me that it is NT version 4.x, but it did
not say what version of SP was installed.

2. Can I tell when a Windows Update or Service Pack was installed on an NT
machine ?

Thank you very much.

Use winver command. (in the Start>Run dialogue box)

No official way that I know of but you can check the timestamp on the
service pack uninstall folder
\%systemroot%\$NtServicePackUninstall$\spuninst

If the spuninst folder was deleted look for the timestamp on the
svcpack.log file. If that isn't there look at the timestamp on the
folders INSIDE the I386 folder, the newest date on some these folders
and files should be a good indication of the intall time.

Hi FNiles and JohnJohn,

there is actually a much easier way to get detailed auditing information on what
has gone on regarding SPs and Hotfixes.

Get a copy of PSInfo (part of the FREE PSTools pack from System Internals here:
http://www.sysinternals.com/ntw2k/freeware/pstools.shtml )

then from a command prompt type:

PsInfo -h

the programme will return a list of hotfixes and the dates on which they were
applied to the system. As far as I can tell, the programme does this by querying
the date/time stamps of the registry entries in the key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Hotfix

For a detailed run down on Service Packs, Hotfixes and Rollups and how they are
dealt with under NT4 see:

http://nt4ref.zcm.com.au/patch.htm

Hope this info helps.

Calvin.
