    Click to Run may be a good idea on the surface, but deeper down, it’s a pain in the rear. The last time it decided to update my software (which was about an hour ago), it was hogging sometimes over 25% of my CPU for close to 30 minutes (averaging around 20%), plus using hard disk and memory resources all during that time, so anything else I tried to do — even just opening a simple text file — was slowed down to a crawl. It’s all well and good if it makes Office programs available sooner and all that, but if it makes everything else effectively unavailable while it’s updating, then what good is it? Reverting to MSI sounds great, but unfortunately Click to Run was installed as an update by Microsoft Update, so it is reasonable to believe that once I have reverted back to the MSI version, Microsoft Update would merely replace it with Click to Run again at its next convenience, and I’d be right back here again.

    I might be missing something, but it looks like there’s no “Download” option as listed in Step 7. I’m referring to the photo shown under step 5, which closely resembles what I see when I login with my account. Any help to find the MSI download would be much appreciated.
