May I ask how Windows 98/ME/2000/XP determine whether the previous shutdown was an illegal shutdown when booting, and then perform the self-check?

This is not difficult. There are multiple methods. For example, when the system starts, create a temporary file. When the shutdown program is executed, it will automatically delete it. If it is an illegal shutdown, such as power failure, etc., the system doesn't have time to execute the shutdown program, so this temporary file can't be deleted. When the system restarts again, it will check whether this temporary file exists. If it exists, it proves that the last time was an illegal shutdown, and corresponding processing is needed at present...

Then it's the same as the approach of MS OFFICE

I only know that if there was an illegal shutdown on WINDOWS2000 last time, then the startup this time is extremely slow

I'm not very familiar with WIN2000!

Practice makes perfect.
If you want to know, you have to practice. If you power off illegally many times, maybe you can find out~~
Hehe~

Probably!!

hehe, what the person above said is right, maybe it's like that, just because I don't know so I'm asking?
What exactly is going on?
May I ask the person on the 2nd floor, which file exactly is it?

The people who know which file are very few, only Microsoft knows best, after all, Windows is a huge system. By the way, zjktxwd, what on earth are you asking this for?

I have a machine here, and the C drive is protected by Lenovo's hard disk protection card (that is, the C drive restores after restart). I think since that's the case, the C drive is the same every time I start the computer. But sometimes the Windows self-check screen appears, which is quite strange.

I think it might be recorded somewhere on the hard disk. It shouldn't be recorded in that file because I installed multiple operating systems. After an abnormal shutdown of XP once, an error occurred during the process of installing a new XP in another partition, prompting something like a previous abnormal shutdown or hardware problem. After scanning in the original XP and then installing the new system in the new partition, it could be installed normally. So I suspect it's recorded in the hard disk rather than in that file.

If there is a Windows self-test screen, can't you turn it off?

The technology used by the protection card is hard disk mapping method. Simply put, it is to create a virtual disk

There is another situation: the first restart after reinstalling the system by formatting with CD boot after an illegal shutdown last time also requires self-check.

So I think it should be recorded in the boot sector or somewhere on the hard disk, not in a file.
