comment Would a longer PATH environment variable slow down a system?
Also, one thing that can slow it down, is if I had an entry referencing a network drive, and the network drive gets disconnected then it may just say not found file/command or it may take ages. So I put the network drive not too early in the path to lessen that when it happens. So, if a command isn't on the network drive, it should find it fast. If the network drive was early in the path, and got disconnected and it was leaving things hanging, then even commands not on the network drive, would get a slow or no reaction.

comment Would a longer PATH environment variable slow down a system?
re your q, Windows only scans as far as it needs to. Re a comment, Writing out the full path is a hassle. The whole benefit of having a path variable is to avoid that. You can have a directory with bat files that run programs(not sure off hand if that helps when launching straight from start). I have that. And a directory with some small executables. Those techniques can keep it shorter.

comment Using different java versions with different browsers
When you go to chrome://plugins/ and click 'details' do you see two java versions listed? if so, perhaps you could enable one and disable another?

comment Printer bat script
-1 Your first sentence makes no sense. And Your batch script does nothing much, it's the vbs files you run that do things. So it looks like not really a batch question. Maybe you din't set your variables at the top correctly or they refer to things inaccessible.

comment How to block all applications from accessing a connection in Windows 7 firewall?
@Red perhaps this is somewhat like it? stackoverflow.com/questions/11956291/… but it looks painfully complicated if like me one doesn't know powershell. It mentions a custom group name

comment usb port stop working
@muhanad if you updated the BIOS (paricularly if you find USB suddenly stops or in your case, stops completely while it was partially funny before then you shoudl know that )what can happen is USB can be disabled, so you should look for any options in the BIOS about USB to enable it. I'm not saying that'll fix it, but it's possible that whatever problem you had before, updating the BIOS(whether it also helped or not), also might have disabled USB. In case of that event, doing what I suggest there would help at least somewhat. It's possible. I have seen it happen after a BIOS reset.

comment Bash alias with Sed not working
a)you should use single quotes around the sed, as in your first example, and as for the double quote, what if you do \"? b)it's kind of cheating and too easy to be interesting but you could do something like \d22

comment usb port stop working
@muhanad if it was a desktop computer i'd suggest to try changing the power supply. for a laptop, i'm not sure if that applies as much but I suppose take out the battery(no harm) and try a different power supply if you have one.

@David when you have a very simple machine, simple usage, it narrows things down. I remember the Active X running automatically by default problem, and disabling it and having the option to ask for confirmation. And by Win XP SP2 that was gone(and if not then people addressed it then and it was gone). A lot of people use Web mail, no Outlook, and use Chrome even though it doesn't come with Windows. It's not that Chrome is a patch or fix, it's just avoiding a rubbish browser like old IE.

@David Probably a fair point regarding the active x problem with Outlook and the checking of email in IE. But pretty much any edition of Chrome has never had that problem. And in practice, it wouldn't be hard to get somebody to use Chrome.. the person is resistant to installing updates of service packs but nobody said he was resistant to using Chrome or a web browser other than IE.

comment Why is it bad for me if my computer is infected, if I don't notice?
I remember reading about the Windows 98 ping of death, crashing a computer remotely but even that wasn't malware, just a crash. And since windows 98 didn't have a firewall(and if it did then a terrible one I didn't even know of!) then yeah it'd have been worth upgrading 98 to 98 SE. XP has a decent firewall though. Your argument is basically. 'you never know' 'better safe than sorry'. But I am talking about -in practice- so XP, no reason for dialup and firewall not sanely configured and no NAT Router.

@David yes but my point was that nowadays people have NAT Routers not dialup. And even if his XP was an early release, he could still have the firewall configured properly. And I am saying he should make sure no ports are exposed onto the Internet, that rules out a ton of exploits. The fact that you had to pick one that was only relevant on a badly configured firewall and a computer on dial up with ports exposed, and does not require an anti virus or installing updates to defend against. Just the basics of a NAT Router.. and a sanely configured XP Firewall

@David A NAT Router should stop access to whatever port. And the Windows XP Firewall should be stopping that too. One can always go to grc.com or whatever online port scanning site and make sure they don't have ports showing up. Could be an early XP had a bad firewall setting, particularly bad if on dial up so directly exposed. But behind a NAT Router and XP Firewall properly set, that wouldn't happen. Very trivial to check no ports are exposed.
