New ideas for U5R2:
 * 1) Windows® *PD, where * is a roman numeral (1011+101n where n is the number denoted by *)
 * 2) Windows® *PU (1101+101n)
 * 3) Windows® *UD (111+11n)
 * 4) Windows® *PUD (1111+111n)
 * 5) Windows® *UPDU (991+99n)
 * 6) Windows® *UP (901+90n)
 * 7) Windows® *MP (11001+1100n)
 * 8) Windows® I P to MMMCMXCI X P: 1051 to 400851
 * 9) Applicable after &minus; (&minus; I P→951) (extension ranges from 398849 BC(E) to 951.
 * 10) Applicable with other letter( combination)s (&minus; I L translates to 50000001)
 * 11) Windows® *-@ versions where @ is any above letter combination. (400900000001 BC(E) – 398900000001 (– 398900000000000000001 if assuming G-MMMCMXCIX-L).
 * 12) Windows® GMMMCMXCIXL (400900000000000001)
 * 13) Windows® Blackhole (5.06e91) (by then a black hole as dense as water will decay)
 * 14) SP1 (3.842e97) (by then a black hole as dense as aerogel decays)
 * 15) SP2 (6e98) (by then a black hole as dense as vacuous aerographene decays)
 * 16) SP3 (2.6652e135) (by then a black hole the mass of the observable universe decays)
 * 17) SP4, SP4.1 (6.97167e136, 5.57733e137) (SP4: by then a black hole (Schwarzschild radius the radius of the observable universe) decays; SP4.1: by then a black hole (Schwarzschild radius the diameter of the observable universe) decays)
 * 18) SP5 (5.1415e139) (by then a black hole (density that of the observable universe) decays)
 * 19) SP6 (9.88766e142) (by then a black hole (density 1 me/m3) decays)
 * 20) SP7 (4.42068e151) (by then a black hole (density max. sum of neutrini masses every cubic meter) decays)
 * 21) SP8 (1.74876e211) (by then a black hole (surface gravity 1 lP/s2) decays)
 * 22) SP9 (5.420624e272) (by then a black hole (G=(1/7.744e53) m/s2) decays)
 * 23) SP10 (4.55627e581) (by then a black hole (G=((1.616e-35)^3/7.744e53) m/s2) decays)
 * 24) EOL: 10^10^10^10^10^1.1, rounded up iff not integer
 * 25) Windows® SOE (2038-01-19, 3:14:07) & UOE (2106-02-06, 6:28:15)
 * 26) Windows® SOESE (214749-01-01), UOESE (429497-01-01)
