[SOLVED] Time&Date of Installed Programs doesn't display

[psi]

Recently a weird problem appeared in my Delete Programs - control panel well known function.

All programs "forgot" their time&date of install.

This is weird since function

sfc /scannow

says system is Ok.

2 columns just don't display anything.
Also Windows "thinks" that all files on USB drive have size 0 Kb, when prompted to delete one.

this is some odd thing so How do I fix it? Thanks for attention.

malware scan?

All I can is to run Windows Defender. I'll look what it does.

The only tricks I know about but haven't applied yet is Dism.exe restorehealth, that command, just a little bit longer. And Windows DVD booting and repair ("your files are not deleted").

This took me a while.
Did run sfc /scannow from recovery environment, and Dism from installation USB. The command was

dism /image:C:\ /cleanup-image /restorehealth /source:x:\sources\install.wim:1 /scratchdir:temp

(it's not exact typing from memory).
Data is still missing. Not that it prevents from using the system. Just - strange.

that stuff is all read from the registry so something wiped it out. did you use and registry cleaners or utilities recently?

Ouch it's possible, I changed value SilentInstalledAppsEnabled in one branch to 0. Setting it back to 1 didn't work. Though probably I did ran 1 such anti-telementry program, but can't remember.
Thanks for your expert comment.
