[wpkg-users] Win10 20H2+ and WPKG slowness...

[Kris Lou]

Perhaps this?

<snip>
function scanUninstallKeys(nameSearched) {
var uninstallPath = new Array();
var scanKeys = new Array();
scanKeys.push("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall");
if (is64bit()) {
// scan redirected path as well (assures that 32-bit applications are
// found)
scanKeys.push("SOFTWARE\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall");
}

// try regular expression matching
var regularExpression = true;
for (var i=0; i < scanKeys.length; i++) {
var regPath = scanKeys[i];
/*
* recursive registry reading is very slow with WSH. Therefore supporting
Sub-keys in uninstall entries slows
* down uninstall key scanning dramatically. So I leave it off for the
moment. Please use registry key checks if
* you need to check an uninstall key defined within a sub-key of the
uninstall registry location
*/

Change your check to see if processing times improve.
