(Seems to work anyway, but)
Log is spammed with

(sdk/lib/rtl/actctx.c:3072) Could not find dependent assembly Microsoft.Windows.Common-Controls (6.0.0.0)

Reporting code is:
https://git.reactos.org/?p=reactos.git;a=blob;f=reactos/sdk/lib/rtl/actctx.c;h=3768f7201b43ab1c92fff31945f0e9861ab5ad85;hb=HEAD#l3057

3058 static NTSTATUS parse_depend_manifests(struct actctx_loader* acl)

But no clue about which file(s) manifest triggers this.

Then, are "Microsoft.Windows.Common-Controls (6.0.0.0)" actually missing?
Should/Could they be included?
