Microsoft Windows startup Registry Settings

INFO: Run, RunOnce, RunServices, RunServicesOnce and Startup:

I believe this is pretty much a bulk of the information set by Xteq X-Setup. For those who don't want to make the purchase for a very simple edit, the following is the except from the Microsoft KB article

General order of loading:

1. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServicesOnce
   
2. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices
   
3. <Logon Prompt>
   
4. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce Not supported in NT 3.51 and ignored by XP and 2000 in safe mode
   
5. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
   
6. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
   
7. StartUp Folder
   
8. HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce Not supported in NT 3.51 and ignored by XP and 2000 in safe mode
   

However,

With the exception of the HKEY_LOCAL_MACHINE\...\RunOnce key, all keys and their entries are loaded asynchronously. Therefore, all entries in the RunServices and RunServicesOnce keys can potentially run at the same time.

Entries in the HKEY_LOCAL_MACHINE\...\RunOnce key are loaded synchronously in an undefined order.

Because the HKEY_LOCAL_MACHINE\...\RunOnce key is loaded synchronously, all of its entries must finish loading before the HKEY_LOCAL_MACHINE\...\Run, HKEY_CURRENT_USER\...\Run, HKEY_CURRENT_USER\...\RunOnce, and Startup Folder entries can be loaded.

Run Command Most Recently Used List Storage

At least for Windows XP, this list is stored in the registry:

My Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU

It looks like there are values \a through \z off of RunMRU, plus \(Default) and \MRUList. There is string value in MRUList: e.g., "nkvlsawbhczeyoijfugrtdxpmq", which determines the ordering of MRUList entries.
