vista slow to open large exe files? – fixed

Have you ever found that windows vista may take around 30 minutes – 1 hour to open a large exe file?

Most people will not notice this since it’s hard to find any programs that even come close to 1GB apart from those who like games – there are many free downloadable games on the internet some that can be several gigabytes usually MMORPGS or FPS’s.

So on topic: this slowness is caused by UAC (User Account Control) which is a supposed security measure which actually just annoys the user when they want to install a program. UAC seems to struggle with large files so you need to disable it.
– Control panel, user accounts, user account control – uncheck the box.

UAC can also slow down the boot time significantly; if vista booting takes more than 2-3 minutes try disabling UAC and that should speed up your boot.

Edit: Let it be known that microsoft admits “The reason we put UAC into the platform was to annoy users. I’m serious,” (David Cross, a product manager responsible for disigning UAC) Source
