Trouble with my right-click START Power user (Context) utility menu

Hi I am not a sophisticated user. I've been searching help videos (sometimes difficult to understand and follow). Trouble happened when I was setting up an external HDD for partition and file backup purposes. Had not done it before and needed to repeat some steps. I also installed WD utilities just to look at what was included and then uninstalled, using Revo. It seems like after that, most of the right-click Start Menu Power (Context?) menu items like Disk Management, Event Viewer in top box quit opening. I suspect this somehow affected some links to these utilities in Power Manager box. I can access them using search or other methods. To rule out Avast, I uninstalled that and enabled Windows Defender, no change. Have run SFC /scannow; some files were repaired but no change with this issue. I have also run Dism /Online /Cleanup-Image / ScanHealth, (also RestoreHealth) with no issues.

More than a week has passed and I've tried many things, but the right click Start Power Context menu apps like Device Mgr, Disk Mgmt, Computer Mgmt, PowerShell, Control Panel don't work. I can still access them via the search window. Since then I thought Win10 2004 might possibly repair it, so I tried that. I've been dealing with some minor bugs in it, but the right click Start menu still is the same. I've been working on other things with it, clearing junk apps, creating a backup system, but from time to time I come back to this.

I just tried the old WinX menu editor and attempted to service the Group 3 list which I guess keeps the links to these utilities, difficult to work it and I had no luck with this. I even tried copying a Group 3 folder with the same default links in it from my other (much newer) HP i7 laptop, it seemed to make no difference. Greg at Microsoft Community tried to help me and I tried re-registering the menu with a refresh instruction in Administrator PowerShell with an instruction from Kapilarya; I probably did it several times, no change. This is the reason for the post: Is there anything left to try?

This PC is an older HP DV-7 i7 8Gb ram 1Tb drive, now about 8 years old. It's my daily driver. I'm not thrilled with 2004 and wish I hadn't fooled with it. But for the most part, I'm about where I was a little over a week ago except for the major update. I've had to do a couple of system restore procedures during the week as I made mistakes and then corrected them. I've postponed 2004 on the other laptop until I gain some confidence with this system and use of resources etc.

Hi Dalchina Thanks much, I will look at these options and report back. Have not tried the new user yet, will try.

Is there a tutorial on changing the username for a PC so that it is done correctly? I had changed it during this period, have changed it back, no effect on anything, really.

Thanks, Don

Hi I performed the user account step taken as administrator; it did not seem to make any difference. Previously I had copied Group 3 links over from another much newer PC I own but that did not work either. My right click Start menu
does have some functions, a few items work. Group 2 partly works, including Run. I did not know until now that I had lost some functions there as well.

I also was able to get the WinX zip and open on desktop as advised, and first deleted non working links and then dragged replacements to Group 3 in File Explorer. They looked fine, but those don't work either.

I am on v.2004, which I am still undecided on but I guess I am stuck with it. I didn't lose any important functions.
Cheers, Don

What are the results of this PowerShell code?

Code:

$Ref = gci 'C:\Users\Default\AppData\Local\Microsoft\Windows\WinX' -file -recurse -force
$Me  = gci "$env:LocalAppData\Microsoft\Windows\WinX" -file -recurse -force
Compare $Ref $Me -Property name, length -IncludeEqual

I opened PowerShell as Admin (using search window) and entered it at the path C:\WINDOWS\system32> (not in my user path, should it be there?) Entered as you pasted it; the same apps (like Apps & Features, System, Network Connections) work as before; the remaining ones plus Task Mgr (group 2) still do not work. It looked promising as I was setting it up! I did make screenshots of my work, since I only last week used PowerShell for the first time to run a different line which was supposed to accomplish the same thing I believe (guided by someone at Microsoft Community) and I was never clear whether PowerShell should be at Admin or User level:

Get-appxpackage -all *shellexperience* -packagetype bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + “\appxmetadata\appxbundlemanifest.xml”)}

I also was directed to or came across this link:
Enable or Disable Right Click Menus In Start Menu of Windows 10

I do not remember trying it and wondered if I should. Somewhere I recall seeing something about Win10 Pro as having group policy editor and I don't believe I have it in Win 10 Home. I've tried a lot of things now with no success (but doing some housekeeping too, along the way).

Thanks, Don
