windows 7 - Win7, after prolonged usage weird keyboard "things" happening, caps lock stuck?

Ok, so bear with me, not sure how to explain this.

So after about 10 hours of constant running my computer/keyboard starts to act weird.

Its as if it has caps lock depressed continually, along with I think a ctrl key.

If I hit caps lock, It works for the letters as it would normally. But if I type . I always get the > symbol. No matter if caps lock is on or not.

It seems to effect mouse functionality to. For instance in gmail, I clicked on a email in my inbox and used the scroll to scroll down the message, but for some reason it closed the email and went back to the inbox.

Num lock and scroll lock are both off.

Any ideas..

It kind of hard to explain the situation because it only happens after a long usage period, and when it does it somewhat renders the computer unusable.

I think it is related to this post Caps Lock is mapped to Shift but it doesn't really make sense to me? How would I all of sudden gain a different keyboard mapping?

EDIT: I forgot that I should've put what solved it directly in the question. What solved it for me was pressing both the left and right shift keys simultaneously.

Answer

One possible reason could be some type of Malware. Use something like malabytes anti-malware to just check quickly. Malwarebytes is a safe program and free.

Else, you might have something messed up in your registry, try downloading Ccleaner. This is another free software that can help you. Ccleaner.

As another option you can go into 'control panel' -> 'region and language' and make sure your keyboard is the right setting.

If it is a wireless keyboard you may need to replace the batteries or make sure nothing is obstructing the connection. If it is wireless just conduct a little troubleshooting.

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
