If you're like me and you rather dislike the Menu/Application Key on the keyboard and would rather have it be more useful (such as if you use an international layout), this registry patch may be of use to change the Menu/Application Key to the 102nd key, as found on keyboards such as UK, German or other European layouts.
If you try to view characters outside the Basic Multilingual Plane (Plane 0) in Unicode such as Emoji, extended Chinese (plane 2), or ancient script characters in plane 1 (such as Egyptian or Babylonian), you may receive two boxes where the extended Unicode character was supposed to appear. A minor tweak to the registry is all that is necessary to enable the display of characters outside the BMP under Windows 2000.
If you do a clean install of Windows Vista, 7, 8.x, or 10 on certain machines (such as an IBM/Lenovo ThinkPad T61 with an SXGA+, WSXGA+ or WUXGA display), the installer will less-than-helpfully select a larger global DPI setting than you might want or need (I tend to prefer 96 dpi on SXGA+ and WSXGA+ displays rather than 120 dpi, and 120 dpi on WUXGA displays rather than 144 dpi); these registry files will set the global DPI to your preference
After installing Update Rollup 1 (KB891861) under Windows 2000 SP4, you may experience an abnormal increase in CPU usage and temperature on a multi-core or hyperthreading processor (see KB919521 for more information) such as a Core 2 Duo, Pentium 4 HT, AMD Athlon 64 X2 or similar. This registry patch will correct the issue and restore normal idling functionality.
Under a default installation of Windows 2000 (SP3 or later; see KB305098) or Windows XP (SP1 or later; see KB303013), 48-bit LBA is not enabled by default; if you are using a hard drive of about 137GB or larger, run this patch in order to access the entire capacity of the hard drive without risks of data loss or corruption (notice: your BIOS must also properly support 48-bit LBA for this patch to work!)
Notice: rename from .txt to .reg before running; I assume no liabilities for any damages caused by misuse
