Microsoft's build 18362.356 (KB4515384​​​​​) for its Windows 10 May 2019 Update (version 1903) rolled out on Tuesday with security improvements for Internet Explorer, Microsoft Edge, networking tech and input devices – and a CPU usage fix that, for some, has broken desktop search.

The security tweaks address a variety of speculative execution side-channel vulnerabilities known as microarchitecture data sampling (MDS) for 32-bit x86 versions of Windows. Intel dealt with the CVEs at issue – CVE-2019-11091, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130 – in May.

The update, released concurrently with Build 17763.737 for the Windows 10 October 2018 Update (v1809), also includes security enhancements for assorted Windows components.

Microsoft says its update fixes a high CPU usage problem associated with SearchUI.exe reported by a small number of users who disabled searching the web via Windows Desktop Search.

But its fix has nixed SearchUI.exe for some. Those griping claim SearchUI.exe, a part of Cortana, won't launch after installing KB4515384.

"What a mess – I had the original issue with SearchUI.exe and it sending my CPU to unparalleled heights and showing a big black pane of nothing," wrote Reddit user cyrenaic101 in a complaint thread. "So I uninstalled that turd. And then here comes the 'fix' KB4515384. Search completely broken..."

    Simple explanation: their telemetry code entangles everything. Spooky action at a distance.

    That is scary as fuck to even contemplate. Let alone realizing you're probably correct.
