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_MACHINESoftwareMicrosoftWindowsCurrentVersionRunServicesOnce
  2. HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunServices
  3. <Logon Prompt>
  4. HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRunOnce Not supported in NT 3.51 and ignored by XP and 2000 in safe mode
  5. HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun
  6. HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun
  7. StartUp Folder
  8. HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRunOnce Not supported in NT 3.51 and ignored by XP and 2000 in safe mode


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 ComputerHKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerRunMRU

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.
