Several users of Sage 100 and Sage 100cloud have reported Sage100 slowdowns shortly after applying a Microsoft Windows system update. This doesn’t appear to impact all users which may be due to not everyone applying Windows updates at the same pace.
The issue has been reported by several users on the Sage City community beginning in June 2017 and described as:
Updated a few machines to 1703 and had some issues with Sage100 2016 being laggy. Windows would take 5-10 seconds to close or open. I then rolled back to the previous build and all was fine again.
Until recently the primary way many users dealt with this slowdown was to roll back the Windows update. Users report that there is a 10-day window within which to revert to the prior Windows version.
Now another potential solution has appeared and several users say this has helped to speed up their workstation running Sage 100 or Sage 100 cloud.
From the website Tenforums:
…here is how to fix it:
1, Hit start menu and type “Defender”, it should bring up “Windows Defender settings” entry, so open it.
2, Another juicy part – if you use another AV software, like for example in my case – ESET, then you would naturally assume everything Defender related is disabled, and you would be wrong. If you use Defender, you will be brought to the Windows Defender Security Center straight away, but if you don’t, you will end up on a Settings page saying that Windows Defender is not available because it’s turned off. Click “Turn on Windows Defender Antivirus” – don’t worry, your AV software will disable it again straight away.
3, Once you are in Windows Defender Security Center, Click App & browser control button
4, Scroll all the way down, to Exploit protection, and click Exploit protection settings text
5, Once on Exploit protection page, set Control flow guard (CFG) to OFF.
6, It will prompt you to restart your PC
7, After the restart, enjoy your smooth Windows experience again
Although this may not work in every case – it’s worth trying to see if you can bring an impacted workstation back to full speed. One user on the Sage City forum reports that the Spring Creators Update (due April 2018) may cure this slow speed issue without the need to perform the fix noted above.
