Well...the first thing to do at any forum or other situation where anyone can say anything...is to assess the plausibility/reliability of the speaker/writer...to make the statements he/she makes. Although every member may intend to assist with their comments...not every post is headed in that direction.
My basic rule when participating in any forum...is to assess the creds of the members making comments. Any member can take a look at previous participation...individual posts by another member...and so on...and determine if such pass the most obvious tests. I also look at manner presented (preferring literacy and organization over rambling)...and I recognize that many members feel that obvious answers to that which they do not comprehend...lends itself to "quick fix" solutions and/or the assumption that "it must be malware."
I will also say that...comments by those with a record of providing assistance in the past...is a good indicator, IMO, while also recognizing that new intelligence/knowledge comes into the forum daily.
If you scan the various posts/topics in a given forum...you can quickly assess the quality of suggestions/comments that are made by those seemingly dedicated to assisting.
And...while not infallible or all-knowing...the BC Staff (notably the Advisors) are here to help and have proven track records indicating such.
Each person must find their own technique for judging/evaluating quality of suggestion/comment...I can only tell you how I do it
Lastly...you should try to remember...computers are very sophisticated devices, employing sophisticated programs. When things go wrong with a computer system, there could be hardware, software, or malware issues. When you state your sitution, you provide the minimal amount of information that may be necessary to give someone an idea of what the problem (assuming there's only one) "might" be...not what it is. For someone to read the data you provide and make an analysis (as opposed to guess) of what might be the problem...well, it's done without seeing the computer or having the ability to test this or test that.
Troubleshooting with hands-on is not a science. Troubleshooting without hands-on is more difficult.
It may seem to you as if there ought to be easy answers to computer problems...sometimes there are, sometimes there aren't.
As or data requested...members do request or review the same data in the same way. What one person thinks may provide clues...may not be useful to someone else, their experience/knowledge may lead in a different direction.
Generally...I think that...when members see a topic going down a certain path with the OP responding to another member...they sit back and wait for that path to be abandoned or concluded successfully before commenting in the topic. I think of it as a courtesy, but it may not be the best thing for the OP. It happens.
I butted in because I saw a comment as "bad advice", not because I can tell you why your boot time is slow
You made several comments hinting at malware, but you countered that by saying that you don't know much about computers. If your problems began with Windows Update...that's kind of a circle, IMO...since Windows Update and malware are not synonymous.
On the other hand...users having problems because of or with Windows Update...are ubiquitous.
What I would suggest...if your problems truly began with an update from Microsoft...try running the chkdsk /r command on your Windows partition.
Start/Run...type chkdsk /r and hit Enter. Type Y in new screen and hit Enter. Reboot your system, the command will execute a file check before booting into Windows.
If your problem began with something other than Windows Update and you suspect/know that your system is infected...you need to tell us that and we can move your topic to an appropriate forum.
