Regardless of the 8.3 tweak being set or not, is a solution being worked up at Alwil?
Due to your own success, your users have placed their trust in Avast. A reboot due to a legitimate tweak made available in a normal windows environment, regardless if there are debates on its benefit, is unacceptable to the common user. Not everyone is going to come to the forum to read the "workaround". They will simply fall off the edge of the planet without saying goodbye.
For all of the machines that I have installed this on, my phone will be ringing to give them a different solution that will work in the 8.3 tweak environment.
Please think about your position. If you CAN make a quick and easy update that will FIX the ISSUE, regardless of the fault of the ISSUE, then please make it so.
