Building on @Krisz's and @a0z's I present this sick on liner to disable Quickedit right from cmd.exe shell or a .cmd script.

I need it for a .CMD script, however calling powershell.exe -Command with ', ", ~, | and & is absolutely impossible, not even half of it can be escaped properly in an .CMD. So in-between Base64 is the way.

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Command "$Type = [System.Text.Encoding]::ASCII.GetString([Convert]::FromBase64String('dXNpbmcgU3lzdGVtO3VzaW5nIFN5c3RlbS5SdW50aW1lLkludGVyb3BTZXJ2aWNlcztwdWJsaWMgc3RhdGljIGNsYXNzIENvbnNvbGVNb2RlU2V0dGluZ3N7Y29uc3QgdWludCBFTkFCTEVfUVVJQ0tfRURJVCA9IDB4MDA0MDtjb25zdCB1aW50IEVOQUJMRV9JTlNFUlRfTU9ERSA9IDB4MDAyMDtjb25zdCBpbnQgU1REX0lOUFVUX0hBTkRMRSA9IC0xMDtbRGxsSW1wb3J0KCJrZXJuZWwzMi5kbGwiLCBTZXRMYXN0RXJyb3IgPSB0cnVlKV1zdGF0aWMgZXh0ZXJuIEludFB0ciBHZXRTdGRIYW5kbGUoaW50IG5TdGRIYW5kbGUpO1tEbGxJbXBvcnQoImtlcm5lbDMyLmRsbCIpXXN0YXRpYyBleHRlcm4gYm9vbCBHZXRDb25zb2xlTW9kZShJbnRQdHIgaENvbnNvbGVIYW5kbGUsIG91dCB1aW50IGxwTW9kZSk7W0RsbEltcG9ydCgia2VybmVsMzIuZGxsIildc3RhdGljIGV4dGVybiBib29sIFNldENvbnNvbGVNb2RlKEludFB0ciBoQ29uc29sZUhhbmRsZSwgdWludCBkd01vZGUpO3B1YmxpYyBzdGF0aWMgdm9pZCBFbmFibGVRdWlja0VkaXRNb2RlKCkge1NldENvbnNvbGVGbGFnKEVOQUJMRV9RVUlDS19FRElULCB0cnVlKTtTZXRDb25zb2xlRmxhZyhFTkFCTEVfSU5TRVJUX01PREUsIHRydWUpO31wdWJsaWMgc3RhdGljIHZvaWQgRGlzYWJsZVF1aWNrRWRpdE1vZGUoKSB7U2V0Q29uc29sZUZsYWcoRU5BQkxFX1FVSUNLX0VESVQsIGZhbHNlKTtTZXRDb25zb2xlRmxhZyhFTkFCTEVfSU5TRVJUX01PREUsIGZhbHNlKTt9cHJpdmF0ZSBzdGF0aWMgdm9pZCBTZXRDb25zb2xlRmxhZyh1aW50IG1vZGVGbGFnLCBib29sIGVuYWJsZSkge0ludFB0ciBjb25zb2xlSGFuZGxlID0gR2V0U3RkSGFuZGxlKFNURF9JTlBVVF9IQU5ETEUpO3VpbnQgY29uc29sZU1vZGU7aWYgKEdldENvbnNvbGVNb2RlKGNvbnNvbGVIYW5kbGUsIG91dCBjb25zb2xlTW9kZSkpIHtpZiAoZW5hYmxlKSB7Y29uc29sZU1vZGUgfD0gbW9kZUZsYWc7fSBlbHNlIHtjb25zb2xlTW9kZSAmPSB+bW9kZUZsYWc7fVNldENvbnNvbGVNb2RlKGNvbnNvbGVIYW5kbGUsIGNvbnNvbGVNb2RlKTt9fX0='));Add-Type $Type;[ConsoleModeSettings]::DisableQuickEditMode()"
