A little worried about a W10 update, its duration and the cleanup.

Thank you for all these explanations.

That being said, and without presupposing that it was you who made this mention, I would have preferred to decide for myself that the issue was resolved.

@Tessel75One must therefore be patient with the updates, and the message ''cleaning'' is very recent. I also understood that it's to compact (reduce the size of the update) the corrections of the update, which doesn't change the fact that some are long, but back in the day, it was a bit similar for XP and Windows 7, although the latter hasn't quite kicked the bucket, as there are still small updates available.

I didn't mark your post as resolved even though I could have done so.
It's the Moderation.

@pistouriRe-Good evening,
Regarding my comment, it's precisely because I didn't want to imply that I suspected so-and-so that I wrote "without presupposing". Moreover, I have had you as an interlocutor several times, or I have been able to read other interventions of yours, without ever having to witness such practices.

As for the core of the matter: for MS to do a little cleaning up is quite good, but given the current circumstances and all the hacking that's happening everywhere, I had some reasons to be concerned.

Thanks again, and have a good weekend.

@Tessel75Hello,

Disk Cleanup for Windows 10 Cumulative Updates

Microsoft is cleaning up:
To get back to the cleanup, Windows Update performs a disk cleanup during certain updates.
More specifically, here’s what Microsoft says:

Cumulative updates for Windows 10 mean that the content of previous updates remains on the hard drive and unnecessarily uses up space. This update forces the removal of obsolete cumulative updates and allows for regular component cleanup tasks to free up disk space.

Note: Disk space is not freed up immediately after installing this update.

After installing cumulative updates for Windows 10, you may find that the reduction in available disk space is greater than expected. A lack of available disk space can prevent systems from receiving future Windows updates or upgrades.

However, it should be noted that W10 and later have an automatic disk space cleanup (and not just for temporary files).
This option may not be enabled by default, so you need to check it.
To do this, go to Settings --►System --►Storage
Check out this CCM tip --► Configure reserved storage space in Windows 10

CCleaner (Not recommended) or similar software also cleans temporary files, but in the case of update cleanup, although it does the disk cleanup job, it removes obsolete update files, especially during corrections of patches, and that’s what happened with one of the latest updates.

I spoke a bit hastily when I said that the word "cleanup" was new in a W10 or W11 update.
In a sense, that’s true, but it should be noted that it existed in Windows 7.
==► What does "cleaning, do not turn off your computer" mean?
Although you can disable the message (in W7), I do not recommend it from W10 onwards and I am not sure that the registry key even exists, although one could create it or have it as a ready-made .reg file.

Microsoft has managed to make Windows 10 updates much less painful than those of previous versions.

==► Update files take up a lot of space on the PC disk if we don’t remember to delete them

As for hacking, you don’t need to worry; until proven otherwise, a hacker has never included malicious code in a Windows Update, but it is true that hackers have a lot of ideas and imagination behind their heads.

PS:
Regarding your note, moderation can mark a topic as resolved if they see fit.
I changed the title of your question to something more appropriate considering your trend (your question is now visible on Google, whereas before, with a basic title, it wasn't and will undoubtedly be read a lot).
Even if you read some of my interventions or I helped you, I don’t always remember the 'pseudos' of the respondents.
Here, you are posting as a 'member', I don’t know if you have a CCM account, but you could create one if you wish.
For example, this would allow you to add an image using the tool available when you respond or comment instead of using an image host.

Have a great weekend.

@pistouriHello Pistouri and Tessel75

By the way... Tessel75, you're not posting as a member (username grayed out)... but as someone who is not registered... or registered but not logged in. By the way, there is an account Tessel75... : https://forums.commentcamarche.net/profile/user/Tessel75

Apparently not used for a long time, it would just need to log in (if it's really theirs) to have the topic in their follow-ups....
