  7. Minimo Cache: This is the cache folder for Minimo.
  8. NetFront Cache: This is the cache folder for NetFront v3.2 to v3.5.

  24. Internet Addresses: This is the list of recently typed URLs in the address bar of Internet Explorer. The entries are stored in "HKLM\Explorer\AddressHistory\".
  25. Boot Count: This is the soft reset counter. There seems to be no detriment in having the number big though.
  26. Bad Theme Registry: Themes specially designed for Windows Mobile 5.0 and above may install a new subkey into "HKCU\Software\Microsoft\Today". Each of these themes install its own subkey which remains in the registry even after changing themes, which makes the subkeys associated with unused themes useless.
  27. Bad Uninstall Registry: This is a list of subkeys under "HKLM\Software\Apps" that are identified as associated with software which are not installed on the system. Read each prompt very carefully before clicking on the "Yes" button to remove them. If you are sure that the reported software is still on the system, select "No". If you are unsure, you should also select "No". Otherwise, wrongly detected software will be removed from the "Remove Programs" list once this item is deleted, i.e. you may not be able to uninstall the affected program from the "Remove Programs" screen if you decide to do so in the future.
  28. Bad Uninstall Files: This is a list of folders under "\Windows\AppMgr" that are identified as associated with software which are not installed on the system. The same risks as "Bad Uninstall Registry" apply.
  29. Dead Shortcuts: This is the list of shortcuts under "\Windows\Start Menu\" that are detected as "dead", i.e. target applications could not be found. Read the prompts carefully if you don't want valid shortcuts to go missing.
  30. Startup Programs: This is the list of shortcuts under "\Windows\StartUp\" that are detected as "dead".
  31. Dead SIPs: This is the list of SIPs (soft input panel, aka input methods) detected as "dead", i.e. not uninstalled cleanly. Some SIPs may still remain in the SIP list even though they have been uninstalled, so they are added to this list. Read each prompt very carefully to ensure that the SIP has already been uninstalled and is no longer on the system. Once removed, you will never be able to use the SIP again. It may even cause severe system instability.

  1. Highlighted in blue: Low risk items.
  2. Highlighted in red: High risk items. Read every prompt very carefully to avoid unpleasant results. Answer "No" to the prompts if you are unsure.
  3. Highlighted in green: These items either depend on device/user settings or third party applications. Tick only those that you are using.
  4. Items highlighted in brown: These items are inconsistent and are not so important.
