Desktop shortcuts disappear in Windows 7:
Vote on this please: System Maintenance tool should not delete unused or broken desktop shortcuts | Microsoft Connect:
This will be one of the annoying rollout gotchas of Windows 7 I’ll be talking about at SMBnation East. I’ve hit this twice in our office. If you leave your computer on (and in SBS world we do) over the weekend, you come back Monday morning and your tax software icons are gone. People in the office are still a icon on the desktop world. I can change their OS out to anything and as long as the apps worked and the icons didn’t move they wouldn’t notice what OS I gave them. (Yeah I’d have to ensure the background image was the same).
For now I’m turning off the system maintenance option because I can’t have the tax software icon be gone on Monday morning. The shortcuts are not broken. Windows 7 is being a bit heavy handed in my opinion.
