Thanks for your response --- So to answer your questions....
1) exact version of Windows used (type: winver from a command line and list the version, windows home/windows professional and language)
2) "when manipulating files/attribute".. please provide steps and what to expect? Eg. change 10x hidden attribute and boom, or change 40x ...
3) what kind of files? Does it matter? .ico/.txt/...
4) how are you manipulating those files.. I take it that you are using Windows explorer, but are you going via the mapped drive or via "\\vmware-host\Shared Folders"
4a) are the files you manipulate in a subfolder? 1 level deep, multiple levels deep..
5) what kind of antivirus/antimalware product are you using in your Windows 10?
6) are you using an antivirus/antimalware product on your host?
Also one thing to try is to see if it still happens after you run Microsoft's System File Checker tool:
This all started happening when I moved my VM from my 2017 MB Pro to the 2019 MB Pro. I let Fusion update the VM to be compatible with 11.5 Fusion on the new machine. Hate to do it, but may have to build a new VM and see if it happens again.
Just can't figure out if it is an underlying VMware Fusion Issue or a Windows issue.
Wish I had more.
