Windows 10: Search and start menu not working at all - Cannot Restore/Rollback

If I click on search on the taskbar nothing happens. If I go into the start menu and start scrolling to find an app that I want to use the start menu refreshes and does not open my app. I have to open the app by going into the store If it's a Microsoft app; Otherwise I have to open apps by going into my pc/os and through programs and activate the exe. I cannot do a system restore as I get an error 0x80071ac5 about one drive. I have since deleted one drive and tried again but still, I cannot restore. I am on Windows 10 2004 and I cannot roll back in settings as I am passed the 10 days limit. This is a 2-month-old Asus Vivobook laptop - So u can add that to the list of computers that Windows 2004 doesn't like.

start button Inoperative search partially working no rollback help


I foolishly upgraded to 10 from 7HP OA 64bit at the begining of the month and all appeared fine except for occasional unexplained desktop background changes until yesterday.
Suddenly the start menu dissappeared and search did not work.
On line info suggested this was common and suggested a fix using powershell
Fix failed
With no start menu I struggled to access restore or similar options
Found access to restore and selected most recent retore failed and no boot
Several Blue Screens later and promises to repair etc non of the restore points were viable. I had no boot
Following on screen suggestions I tried Reset ...... Failed due to Cortana problem ???? said Boot device inacessable etc etc
Eventually found access to safemode and managed to boot and restore worked on third attempt.
Roll back to win 7 failed due to all folders in win old being empty or deleted by MS before the month was up
Still no solution to start menu or search cannot rollback and cannot download an ISO as Gateway/acer product key will not verify
No Cortana because it is now not available for english english and no edge as I cannot find it and no other apps
I have a broken system but I have managed to restore some functionality although it is very slow.
Some one suggested a conflict with Avast so have removed Avast and Defender is running

Advice will be gratefully received
Thanks
Dave

WINDOWS 10 START MENU and SEARCH STOPPED WORKING - FIXED all -- BUT APPS DISAPPEARED...

• AUG 24, 2015:
• START MENU and SEARCH stopped working --(AND many items on the task bar disappeared or stopped working). Also the apps were no longer accessible.
• To fix, I tried all the fixes suggested by MS support that I found in the answers to others with the same problem--but none of it worked.
• I FIXED THE PROBLEM by using RESTORE ...(YAY!!!)... and restored my system to the state it was in before the last update I had received.
• It took forever.. (I went to bed and let it run overnight) BUT IT WORKED! EVERYTHING IS WORKING: start menu, search, etc. etc. Everything was back and working except for the APPS... no apps appeared in the start menu and the 'app store' icon was still
  missing from the task bar.
• After all was restored, I did a Windows 10 UPDATE, to get back the updates that were removed when i did a system restore--everything worked out fine!
• HOWEVER, all the APPS were still missing
  from the start menu and the MS APP STORE icon is still missing from the task bar.
• BUT I am able to add apps back to the computer (and to the start menu) one by one.
• ...... Anyone know of a way to restore all the apps to my computer and restore the "Store" icon back to my task bar?
