Of the 8 PCs I've upgraded to windows 10, mine is the only one having problems, but I'm also the only one who does any "real" work on my PC
Since our last conversation, I've had to rebuild the PC again twice, after duplicating the original errors. The key error is "Extended attributes are inconsistent" with past windows versions, this is commonly tied to the UAC's sound, but I don't think this is the case in this situation.
One possibility, is the disk cleanup utility (and CCleaner) is stripping out the extended attributes across my file system, thus disconnecting my standard user account from being able to use the "run as administrator" feature. If so, this is not user error, this is a substantial flaw in the system.
The other possibility, when installing programs under the admin account, it is not connecting administrative type programs to the standard user account.
Normally I would troubleshoot extensively until I was 100% certain what is causing it, but I'm moving next week, and I've already lost 3 days messing with it, so for now it's up and running and working well.
On this latest install, I've installed all programs under the standard user login, using admin credentials.
