Same here. WU still alerts me when updates are available for download and installation. My system is a Toshiba Satellite L300 running Windows 7 Ultimate SP1 x64. It has Intel Pentium T4200 dual core cpu x86/64. Originally this laptop was running Vista home Premium OEMAct. Thank you to @abbodi1406 and everybody else here who do this brilliant work.
Only a Monthly Rollup would disappear from the installed updates when you install higher / newer Monthly Rollup because all are internally chained by same package name similar to KB2952664, which got many many versions
KB5053620 March 2025 security monthly quality rollup for Windows Server 2008 R2 64-bit (Note: It updates Internet Explorer 11 to version 11.0.370)
Used WU to locate, download & successfully install March cumulative security update roll-up. 1 month closer to full Linux conversion. Sigh. ;>))
