Addressing Slowness on a Win8 or Win10 Network

One of the strengths of LiquorPOS® has always been the speed it maintains at the point of sale.  Other functions throughout the software should also be fast and smooth.  However, this does require a network that properly supports the software.  Recent upgrades to the security features in Win8.1 and Win10 seem to have had quite an impact on network speed in a number of store locations.

Assuming you already have a solid network that was processing at the speeds you were accustomed to and has only recently showed a marked slowness, you might try the following:

Updates to Windows Defender seem to have made it far more aggressive in its influence on your system.  Two changes make quite a difference in improving the performance of LiquorPOS®.

Add the LiquorPOS® files to the Exceptions in Windows:

1. Type Windows Defender in the Search window and the option will come up, click on it.
2. Click on Virus and Threat Protection.

3. Click on Virus and Threat Protection Settings.
4. Scroll down until you see Exclusions and then click on Add or Remove Exclusions.
5. Click on Add an Exclusion and Select Folder.
6. When the File Explorer pops up, select the LPOSDATA, LiquorPOS and LPOSMgr folders if you are working on the Server for your system.  On the Workstations, select the LiquorPOS folder.
7. Click Yes to allow the changes to be made and you will see the selected folders appear. You will need to select each folder individually and click on Select Folder, allow changes made to your system and repeat for the next folder.
8. Once you see all the folders you need to be excluded, close out of the Windows Defender Security Center.

Add the LiquorPOS® application to the allowed applications in the Windows Defender Firewall.

3. Click on Allow an App Through Firewall.
4. A list of Allowed Apps will appear. Click on change Settings and then Allow Another App.
5. When the Allow an App Window pops up, click Browse and navigate to the C: Drive and then to the LiquorPOS folder. Highlight LiquorPOS.exe (also/or the LiquorSales.exe if you use the Sales Screen only version). Click Open.
6. Back at the Allowed Apps screen scroll down to make sure LiquorPOS BackOffice is checked and that there is a check mark in at least the Private column. Depending upon the setup of your network you might need to check the Public column as well but it would be preferable not to.
7. Click OK and finish by closing out of the Windows Defender Security Center. You should not have to reboot your system to see improvement.
