"Are you operating an Administrator account? What changes or modifications are you making, if any?
When you reinstall are you wiping all partitions off the hard drive or SSD which is the definition of a "Clean" install, with all other drives unplugged, selecting the Unallocated Space and then clicking Next to let Windows create and format the needed partitions - which makes it foolproof?"
Yes, I'm the administrator. Fresh install using the Windows 10 .iso from Microsoft's official site. Formatted and cleaned disk using fdisk in a command prompt during ISO USB boot then letting Windows create it's primary partition.
"Next time you install do this gold standard Windows 10 Clean Install which compiles the best possible Install of Windows which will stay that way as long as you stick with the tools and methods given, has zero reported problems, and is better than any amount of money could buy:*http://answers.microsoft.com/en-us/windows/wiki...*. Read over it first, take notes, ask back any questions so you're prepared."
I'm aware of this process. I've created many PXE systems to install Windows, and Linux OS's to multiple laptops and PC's at once at my previous institution, and have worked help desk for over 20 years. This problem is pertaining to my home systems, where I try to keep "work out." However, this is not a problem I encounter often, just once in a blue, as every year or two, I like to do a fresh reinstallation of Windows for security purposes and for a fresh start. However, this problem comes along usually when a new update comes around. And if you think I'm the only person with this problem, just search for "Windows taskbar calendar does not open," "search does not work in Windows 10/11," "windows mail crashed upon opening," as all of those problems are linked with this problem, and it has to do with privilege's regarding TrustedInstaller, and/or simply changing UAC to a lowered security level (to get rid of the horrid black background when installing non-Microsoft signed apps, like FileZilla for example.)
"You can even adapt it for Windows 11 as it's worked the same since Windows 7 for millions of consumers who have never come back to report another problem."
I honestly wouldn't touch Windows 11 with a 10 (pun intended) foot pole. Especially since I've been an insider for the past year, and now my previous OS is held hostage to the outdated dev version due to Microsoft's negligence being that you cannot do a direct install to the public release if you're using a developer version... But that's a story for another time.
Anyway, this thread is getting convoluted with mostly useless information between the both of us. Let's get back to TrustedInstaller, which is the issue, because once I changed the file permissions from TrustedInstaller to my Administrative account, which I use as my main and only account, all my issues were gone. Let's talk about that, since you're a Microsoft MVP, I'm wondering if you can tell me and thousands of other people why this is happening.
Look forward to your response.
P.S. I just made a thread about this with another account, and someone else recently is also having the same issue.
