Windows 10: Permmision issues on windows programms, not affecting mmost 3rd party programms.

So i dont know what happened i restarted my pc and now when i try to open applications i get this error "windows cannot access the specified path or file. you may not have the appropriate permissions". Windows start and nothing on the taskbar responds or they show preivously mentioned error. I checked all the permissions in regedit and all looks fine and i have confirmed that all the hives have deafullt permissions. My michrophone and headphones cant recieve or send anything. I can still open cmd registry edit and some other programmsalso as admin variants This concerns a win10 desktop. Any

Where are my programmes listed using Windows 10

I have just bought a new laptop with windows 10 and have downloaded various programmes. Where are they ?!

I can't find a list of them anywhere. They are not added to those daft boxes on the front screen and they are not in the list when I click on the Start button, just some are listed but not many and in an order I don't like, last purchased then frequently
used (not) and who wants 'suggestion for paid programmes' ?)

Thx in advance

 

Uninstalled programmes

Is there any way to list recently uninstalled programmes?

I'm using Windows 10 Home 1709

 

"none finding" of Windows 10 programmes.

Trying to update Windows 10, to version 1803.

Update reaches 49 %, then advises me that Avira AntiVir can't be uninstalled, and I have to do this myself.

I have tried " add/remove programmes from the control panel - not listed

Settings and troubleshooting - no programme listed.

Regedit and into local programmes - not listed

I have tried the Deep search programmes from "Revo unistall" - can't find it.

I have tried the deep search from "10bit uninstaller" - can't find it.

HELP.

What do I do next to enable me to run my Windows update, please??
