MBL Community: How To Fix File Copying Problems In Windows Vista
I spotted a very useful tip on One Tip A Day to fix the problems introduced by Windows Vista when large files are moved, copied or deleted. Within Windows Vista this a very slow process, due to problems with Vista’s Auto-Tuning feature.
This was the only major outstanding issue I had with Vista. I have 5 HDDs in my main PC and I’m constantly moving files between drives. Not only would this sometimes take ages, sometimes the process wouldn’t complete as Vista would run out of memory.
Fixing this was easy after following One Tip A Day’s instructions. To Turn off Auto-Tuning:
- press Ctrl+Shift+Enter to open the Command Prompt. Choose run as admin
- Reboot
type in: netsh int tcp set global autotuninglevel=disabled
If you have any problems, then to turn auto-tuning back on type the following in Command Prompt:
netsh int tcp set global autotuninglevel=normal

Nice tip. Indeed Vista has a somewhat not stable behavior as far as performance is concerned.
