Microsoft has added several registry values to be used by the Add/Remove Programs (ARP) system applet.
Software packages have to register to the following registry key to show up in ARP:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
An application can either use it's name or a generic product GUID. Known product GUID's are:
{00010409-78E1-11D2-B60F-006097C998E7} Microsoft Office 2000 Professional

Known bugs:
1.
If "InstallLocation" is not set properly Windows 2000 reports size of Uninstall folder instead !
“C:\Program Files\InstallShield Installation Information\{PRODUCT_GUID}”
2.
If "DisplayIcon" is not set properly Windows 2000 relies on information stored in the following registry path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Management\ARPCache
"SlowInfoCache"
"Changed"
SlowInfoCache stores the path to the icon source as well along with a checksum. If this value becomes corrupted
Windows 2000 diplays a placeholder instead of the correct icon (red cross along with name computer graphic).
