Overview
- Microsoft is trialing a boot-time preload of File Explorer in Insider Dev and Beta build 26220.7271 to address slow cold opens.
- Windows Latest measured a drop in first-launch time from about 2.0 seconds to roughly 1.3 seconds, with RAM use rising from around 32 MB to about 67 MB.
- The improvement is more pronounced under heavy system load, though elements such as the context menu remain sluggish.
- Coverage is split, with some calling the gain worthwhile and others labeling it a workaround that could add up if more components are preloaded.
- Microsoft has not committed to a general release, and the findings come from early Insider and virtual-machine testing that may not mirror wider use.
