Updating microsoft works
Please read the entire post & the comments first, create a System Restore Point before making any changes to your system & be careful about any 3rd-party offers while installing freeware.Soon, when you buy a new PC, it won't support Windows 7 or 8.If you use Avast antivirus, make sure that it too is updated to its latest version.
It's not usual for old PCs to fall short of the minimum requirements of a brand new operating system, but in this case, the opposite is happening.
When you upgrade to Math Type 6.6 it will retain any changes you've made in your installed version of Math Type, including keyboard shortcuts, toolbars, preferences, etc.
Math Type 6.5 equations are compatible with Math Type 6.0 and 5.0 equations so you can continue to work with other Math Type users even if they haven't upgraded yet.
Math Type 6.5 will also retain any changes you've made in your current version of Math Type, including keyboard shortcuts, toolbars, preferences, etc.
If after upgrading to Windows 10, you find that some of your Office 2013 Word, Excel or Power Point documents do not open, then this post may be able to help you.
