Windows 10: 40GB gone after an update?

Hello,I recently did a simple update on my computer. It was only a cumulative update, so I thought nothing of it.But when I restarted my computer, suddenly the free space available on my hard drive went from 100gb down to 60gb I have a 200gb ssd.I'm really not sure where those 40gb went, or what could possibly take up that much after an update.I did notice that in the storage settings, apparently 94gb are for "system & reserved". Most of that looks to be virtual memory 40gb, though I do have 40gb of actual memory so I can somewhat understand that and the hibernation file 16gb.Is that

:)

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

 

Windows Updated(16299.309).KB4088776 Restart is required to complete.

Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.

 

Is 40Gb normal for AeroGlass?


Just a quick question about installing the Anniversary Update.

My C drive is 120Gb in which 110Gb was used. The install prep said I need to have at least 20Gb free so I looked to move data temporarily to free up space. I noticed AeroGlass 10240 folder was nearly 40Gb alone so I moved that data to another drive. I have not moved it back to C drive yet.

I know AeroGlass is a theme that adds transparency to windows but 40Gb? Does that sound right? I don't like AeroGlass that much but maybe a reinstall would be less data.
