If your computer has Windows 10, your computer probably is (or has been) experiencing lengthy updates. These can cause a computer to seem unresponsive. If your monitor is dark but the HDD indicator light on your laptop or tower is flickering or solid, your computer may be in process of an update. Updates may happen in two or more stages.
If you are using Windows 7 or 8/8.1, you may notice changes in Windows features as well. Microsoft is applying certain Windows 10 changes to Windows 7 and 8.1 as well. If you notice changes in the display screens or locations on certain functions, it may be due to these updates. As a result, it can be difficult to know whether something has gone wrong or whether it has been changed by design.
If you notice a loss in functionality - that means, if certain icons simply stop working - it may be due to an update process not being fully complete. Since these updates are downloaded and installed in stages, errors or omissions in one update may require a subsequent update to complete the process or to correct glitches in code.
In most cases the updates going on currently are related to the "Anniversary Update" and related update packages that Microsoft began rolling out recently. Be aware that these updates may cause changes in your computer settings and display. These changes will vary with each computer.
On my own computer equipment at home, the recent updates make the Microsoft Edge browser as well as Microsoft's "Cortana" search features more conspicuous. Also, the updates have relocated and sometimes "hidden" some of icons I use most frequently. These changes can be corrected fairly speedily to get your computer back to the way you're accustomed, or close to it.
Using Microsoft Edge and Cortana seems like a big leap at first, but with a little tutoring can get to be second nature. Chrome and Firefox web browsers still work fairly well on Windows 10. Internet Explorer however seems to get very slow and tends to freeze up with a lot of webpages.
If you've lost access to your usual home page, email or internet entry way, usually it's possible to retrieve these fairly speedily.
Whether you're using Windows 10 or and earlier version - 7, 8.1, or even XP or Vista - there are more a more ways to customize your computer to focus on the things YOU want to do with it - and ways to get rid of the clutter that gets in your way. It also is getting easier to migrate from an old computer to a new one, and easier to use more than one device to get to your email and your files, pictures and favorites.
Hope this information is helpful.
