睡不着觉怨床歪

今天收到公司IT部门一封信,立刻让我想到标题这句话.

Dear users,
Please do NOT do below things on your laptops:
1. Change the existing harddisk partition.
2. Install the "Fire-fox" Internet browser.
3. Install any "virtual CD" s/w.
4. Install any non-business related s/w.
We've seen several cases that changes to original laptops system caused the new laptops crash.

Please feel free to contact IT helpdesk for any questions.

还有一句话, 没有知识要有常识,没有常识要有见识,没有见识要会掩饰.
