Windows 10: My windows applications are disappearing, what could be the cause of this?

System: Windows 10 A few days ago mspaint vanished from my computer. I do not know how or why, but one day I right clicked on an image which I wished to edit and scrolled to open with paint.

Windows 10 update: start up and sleep issues caused

Dear Vijay,

Thank you for your response: apologies for slow feedback.

Regarding step 1 - doing a restore point : I tried this twice and twice it failed. Now, the date of the update that caused the issue (13/14 September 2019) has disappeared from the history list. Is there a way of finding it, still?

Regarding Step 2- the list of updates installed: the two suggestions above do not seem to appear in the list in the window "Installed Updates".

There are two updates listed for 13 September - Security Update for Adobe Flash Player and Security Update for Microsoft Windows.

Could you advise what I might try next?

Thank you so much.

 

The 'Photos' app for photo viewing has disappeared.

I do not understand this, when I returned to the PC later today my original settings had returned to the start screen, including one other tile which I had also lost but had not yet re-instated. Also the original list of 'All apps' had returned to the start
screen, including 'Photos'. There is nothing that I am aware of having done that should have caused the original disappearance of some apps from the 'All apps' list and their associated tiles, or that could have caused them to return.

It has therefore been unnecessary to follow your suggested steps, though I have done so anyway and it works as suggested. Note that I had followed your steps 1 & 2 earlier which is why I knew 'Photos' had not disappeared from the PC but was simply not
visible on the 'All apps' list and hence my inability to re-pin the tile.

Thank you for your reply and understanding my frustration.
