Windows @ the MOD
There is a major problem that I can see in the use of Windows systems to "cut costs"; namely the replacement of technically competent, experienced network administrators with newly minted MCSE "Numpty tick box "administrators.
Yes, a numpty will cost you less to employ initially, but won't half empty your pockets in the long run.
"system crippling anti-virus parasitic-ware to dump on top of the Microsoft insecure bloat-ware."
Perfectly put Sir, Norton/Symantec/AVG/Mcafee are probably responsible for half the CO² production on the planet*. Think of all those zillions of PCs running the above cripple-ware, on-demand, then spending 5 or 6 hours a day doing a full file system scan.
* If a google search does, what's the cost of Norton/Symantec/AVG/Mcafee - anyone care to do a study?
