I have attached details for Windows 10 patch/updates I received on 2/13/24 (KB5034685) and 2/16/24 (KB5034763). Both times, when Quicken was opened, Quicken went to "not responding" in Task Manager. On 2/14/23, I first tried current "mondo" patch with no success, then un-installed and re-installed Quicken several times on 2/13/24 and again, no success. After reviewing further, I discovered I had received the first windows "quality" update dated 2/13/24 (KB5034685, cumulative update for .net framework….) so I backed that out and after rebooting, Quicken began responding as it should. I received another "quality" update overnight last night, dated 2/16/24 (KB5034763, cumulative update for Windows 10 Version 22H2…) and experienced the same "not responding" errors again this morning. I backed that patch out as I did previously, and once again Quicken began responding as it should. All seems to be working as designed, at the current time. I have created new backups of my Quicken data as a precaution.
I am wondering if anyone else has experienced the same issue? I do receive automatic Windows updates but may disable for the short-term, to see if there are any updates/solutions identified by Quicken.
