What About Uninstalling SP4?

You can uninstall back to SP3, as long as you opted to make the uninstall directory, by going to Add/Remove Programs in Control Panel and selecting Service Pack 4. But with some caveats:

• if you didn't have IE4 installed previously, you have to re-apply SP3 for cryptography to work.

• if you ever have to reinstall SP3 again, you can't opt to replace some of the newer files left by SP4 when prompted to do so:
  Samsrv.dll
  Samlib.dll
  Lsasrv.dll
  Services.exe
  Msv1_0.dll, and
  Winlogon.exe
  

  SP4 permenantly changes the database structure of SAM so that the older (SP3 and earlier) versions of these files will no longer work -- if you replace them with the older versions, you won't be able to log on anymore!

What about my Notebook?

There are plenty of notebook issues, of course: see the readme for specific makes and models of possible problem units, but basically any SystemSoft-supplied PC Card software should be updated to the latest version (post v3) before applying SP4, or your notebook will cease to function. Lovely.
