uac - Cannot activate .net 3.5 on Windows 8. Can't activate from control panel and never got an installation CD or iso with my computer to use DISM with

I've been trying for about a week now to activate .Net Framework 3.5 on my computer to no avail. I've been trying to activate it via 'Turn Windows Features On and Off' in the control panel as well as separate downloads, including one that was supposed to have all the .Net 3.5 files downloaded with it. I keep getting error code 0x800F0922. My computer came pre-installed with Windows 8 and all I received with it is a Windows 8 Restore disc (Which I don't believe contains 3.5 anyways) with which I have tried running DISM with for sources/sxs several times The progress fills to 100%, hangs there for a minute or two and then returns with 'No operation was completed' or some such. I get the exact same error as well.

Here is a link to my CBS logs. One thing somebody else who was helping me pointed out was that the logs say I do not have presentationhost.exe, despite there being a copy of it and an accompanying .dll in System32 and SysWOW64. There are also a lot of errors for 0x80004005, which means I do not have the proper access to such files. I am an administrator and the only user on my system. On a related note, I cannot seem to do anything involving user accounts in my control panel. Trying to manage accounts, change account type or name and trying to change UAC settings does not do anything more than move my control panel to the background.

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...
