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. ;>))
New updates for Windows 7 Pro SP1 64-bit / Windows Server R2 64-bit (already up to date to March 2025): KB5055171 security and quality rollup for NET Framework 4.8 KB5055561 security monthly quality rollup KB5056456 servicing stack update Note: KB5055561 will update Internet Explorer to 11.0.375 (11.0.9600.22512) and will reboot the computer twice.
I just typed a long post about repeatedly getting an error message when trying to install KB5055171. Then I remembered that it was a .Net4.8 update and I hadn't been using the .Net bypass. Sometimes I even surprise myself with how damn stupid I can be. I've now installed KB5055171 successfully.
My situation was a little bit like yours but I had enabled .NET 4 ESU Bypass from esu bypass v13f settings. I then disabled that setting, then rebooted, then re-enabled and rebooted again and finally I was able to install KB5055684 from Windows Update. So thank you for this! You helped me even if by just accident. =)
For what it's worth I was able to install ndp48-kb5055171-x64_8b54e011ef2523e03e43bcef1f306e5aa59b79f3.exe with only ESU enabled by TSforge.
