MS should bring out a Windows Classic Edition.
Basically an XP SP4 with bugs that are STILL in Win7 and Win 8, (or stupidity) fixed. File copy in Explorer is crazy limited compared with xcopy and ordinary users don't realise that it copies or moves depending on if explorer thinks directories are on same drive letter. They don't know about holding cntrl or shift.
Also the explorer views are buggy.
The Classic Edition should have only safe network clients on by default. It should have 32 bit (faster for some things and needed for old cpus) with NT4 Enterprise PAE on as well as 64 bit. No need to resurrect the long dead XP 64 for Itanium.
