Windows 2000 with Extended Kernel transformed into Windows XP!
How I did make Windows 2000 with Extended Kernel look like Windows XP:
Modified most system files with Windows XP icons.
Modified welcome.exe to look more like Windows XP.
Used ObjectBar 1.6 + WindowBlinds 1.01 (Windows XP Theme)
Used BootSkin XP (Windows XP Bootscreen)
Windows XP sounds are used in
Replaced and modified most applications and control panel applets with Windows XP ones (1. some of them are from windows 2000. 2. ported Security Center and Windows Firewall from Windows XP SP2 to Windows 2000, but it is not-functional)
Windows XP Screensaver on Windows 2000 - I applied to it, but it is unused in video, but the video of it can be found here: https://youtu.be/Wkt3PWW-IXw
WVleft.bmp - Unfortunately, it is from Windows Whistler, since I couldn't find the XP version of the wvleft.bmp.
Used NNN4NT5.exe to think its running Windows XP SP3.
Replaced the Internet Explorer icon with the the one from Internet Explorer 7 and 8, but it is actually Internet Explorer 6.
Windows XP Tour ported to Windows 2000.
Windows Movie Maker 2.6 installed on Windows 2000
MSN Explorer and MSN Messenger on Windows 2000.
Notes:
Blue and Metallic variants of the Luna Theme are only used in this video, because I couldn't find a separate functional Homestead variant of Windows XP Luna theme for WindowBlinds 1.01. As said above, the XP screen saver is unused in this video and the screenshots can be found said above.
Bugs:
WindowBlinds 1.01 are buggy with third-party applications
