- Frequent Bluescreens
- Applications that stop working one day to the next
- WLAN stops connecting to any network one day to the next even after replacing hardware
- 5 reinstalls in 1 year with absolutely nothing but 3 games installed
- Biggest mess in configuration dialogs ever
- Tons of stupid questions
- Inconsistencies in what files are in a directory
Thanks Microsoft for the biggest crap a computer has ever seen. Windows Vista.
