A long time ago I subscribed to a notification from MS on their updates. Most of the critical ones come on the second Tuesday of each month, but they sometimes will show up on the following Thursday or even the fourth Tuesday. This is for both the OS and the MS Office products for my Desktop Win8.1 and the wife's Laptop Win7.0. I perform a manual install on each and both are set to notify me of updates, but allow me to select the install.
I have the GWX Control Panel installed on both machines to prevent any Win10 stuff from being installed. On occasion there are updates that I just "hide" because of the Win10 features. The remaining "critical" updates get installed, whereas I exercise caution on any "optional" updates. At one time I installed some "optional" drivers on the wife's machine only to have to restore everything since it screwed up her audio.
My process is to update my desktop first and make sure all were successful installs, then do the wife's laptop. My i7 machine takes the downloads quickly, whereas the wife's i3 laptop takes much longer. Other than that, there is an occasional slowdown only in locating the updates but no major issues once I elect to install them.
