updates corrupt system files

Before a Macrium backup, I update the system and then check with sfc /scannow before and after the update. With every major update, sfc reports corruption where there was none before the update. Is this normal? Because it just increases the maintenance time.

I wouldn't say it's "normal", but it does happen a lot, to a lot of people.
As long as SFC can repair the issues, you are OK.

As for it being an inconvenience, there's not much we can do about that.

Personally, I don't run SFC before a backup. But I always run SFC after Windows Updates.

Thanks for the reply which was expected. This post is not aimed at the forum. It was aimed at Microsoft developers who regularly read and analyze user issues posted on this forum. I already discussed the use of sfc on one of the Microsoft forums but the reply didn't convince me.

I created various scenarios repeatedly, and your scenario is the logical choice, provided chkdsk /f/v (fix and verify) is executed prior to backup. This is more important than sfc, or dism, based on experience.

I would love to hear your, and the community's opinion on this issue.

Developers scout forums related to their work. I came across Firefox developers, in Mozillazine forum, and Microsoft professionals in MS forums who post links about issues and solutions outside of the Microsoft forums' sphere, something I never saw before.

I also can't recall any Microsoft employee identifying themselves on Windows forums which usually have a disclaimer they are not attached to Microsoft like this one does. Maybe they are on the "dark web"?

I have the same experience as you but not with every update and also on different PCs. Sometimes the log shows that it’s related to OneDrive since I always uninstall the app.

Unfortunately for most users the customizations and uninstalling of built-in features tend to get set back to an as-shipped condition with the twice-yearly Version Upgrades and sometimes with the more-frequent Updates. Most of the unwanted features I ignore them or when possible disable from loading in the background.

Windows updates are not necessarily complete as soon as the "100% - Done" message appears.

@kreemoweet, thanks. This is the logical and best explanation. Otherwise, if the corruption is permanent, it would have been noted on forums by professionals and other users earlier. I search before posting and would have stumbled upon the explanation. — Now, I will wait a few days after an update before using sfc.
