Back in the days of early Windows versions say 3.1 an acquaintance of mine was very miffed about Windows hogging very precious disk space, like back then you might have only had a 30 Mb [I truly can't remember] HDD. Back in 1990?
Anyway being quite a clever DOS programmer he wrote a program for himself which identified every file in the C:\Windows directory which had not been accessed in the previous twelve months - these were removed from Windows to an older drive he had spare.
Yes, Mr. Microsoft's Windows still didn't miss a beat, didn't notice the missing files, and the disk space recovered was quite substantial to disk size back then.
Then again as another friend once said:
"When they develop cheap 25 Tb drives for general use, and MOBO's will have 256 Gb of RAM - Microsoft will expand their latest Windows to consume as much as possible - you see it has always been that way. Microsoft is full of pointless bloat"
