電腦下載了禁止改日期軟件, 可惜日期忘記了修正而安裝了

你首先移除個禁止改日期軟件，然後修改日期。
你說次次開機都是2003.1.1 日子、是因為你部機主板內粒鈕形電池無電。
換粒新電就OK。

你可以還原系統...

Fix-----The easiest way is the run
restore in your PC. In XP, > start.> All programs >
Accessories > System Tools > System Restore.> Restore my computer to an earlier time.In the calendar, find a previous date in bold
number. Try the one just before 2003.1.1Click on it
and follow prompt to restore your system to that date.PC will run restore and restart again when
finished.After reboot, your computer
will roll back to the codition on the date selected. This should take that particular program out of you PC.Don't ever do that again.
Note: This will clear
all programs installed after the restore point selected in step 3.
However, you won't lose all your work done since that date. Good luck!
