// This is BAD ! The Status bit was not initiazted to zero, which causes intermitent
// execution by this function. The problem is that even if the status bit is init'd
// to zero, then we can get the wrong behavior which will cause Office97 installation to
// go wrong.
// See BUG ID 412419
// Here is what woudl happen: Install any app ( say TsClient). This would cause
// an update to a Key in HKDU called Explorer\ShellFolders, just a refresh (no real change).
// Then, if Admin did an logout and login, the call from UserInit.EXE into this
// function (assuming by chance Status=0 was on the stack) would cause deletion of
// that key (ShellFolder). But once Explorer starts, it writes to the ShellFolder with
// a subset of original 19 values.
// The problem is that if then, you decide to install Office97, setup.exe would look
// in the same key for a value called "template" which is now missing. Explorer
// would then create it, but it would point to some other than default location.
// When all was done, our office97 compat script would be looking to where the
// "template" value used to point (the default location), not where it is pointing now.
//
// we decide to disable this func by calling return right here, and instead, rely
// on the TS mechanism to fault in keys.
// Oct 31, 1999
// I have decided to initialize the status var and let this func run, in addition to
// marking the Explorer\ShellFolders as a do-not propagate key tree.
//
// It was discovered that after installing Office2000, when a user clicks on the
// start-menu-> Open Office Docs link, MSI starts to run since user's hive is missing some
// keys.
//
// The reason MSI does not see the keys in HKCU is because MSI has the TS-aware bit set,
// which means that there are no faulting-in for any keys. The same is true for the Explorer.
// On the other hand, when an app such as Office runs, since it is not ts-aware, we
// fault in the keys that office touches. I verified this to work as expected.
// The problem is that when you click on "Open Office Documents", you do so from the
// explorer and when Explorer opens keys in the registry, since explorer is TS-aware,
// those keys are not faulted in. I have verified that if you mark explorer as a non-TS-aware
// app, the problem goes away.
// We made a recent change in TS code (B-bug 412419, bld 2156+) to fix a different
// problem which has now uncovered the reliance of the Explorer to get keys
// faulted in during login.
// Specifically, TS used to fault in all keys at login time,
// regardless of the need. Post 2156, TS faults in only keys upon
// access by non-ts-aware apps. This was to fix a bug based on
// what we considered to be our most informed and well tested opinion. That
// has turned out to be wrong.
// It is too risky to mark explorer non-ts-aware this late, so we must change the fix for 412419.
// This should also make Bruno Amice very happy, since the fix will be as it was
// advocated by him.
