I have been reading this thread, and many of you make good points. I have never disabled system restore myself, however I could see how you might want to reclaim disk space it takes up especially if you do regular backups. Most people don't backup their PCs. At least that's been my experience.
As for UAC, yeah, it looks like launching things as Administrator by default can NOT be done without breaking lots of Metro apps. You can auto-allow processes to elevate when requested, but several of you want to force everything to be elevated by default.
Proceed with caution! There are plenty of good reasons why UAC exists. But here are a couple of things you can do.
First of all, it's not the shortcut that you'd modify for "run as administrator". It's the 'properties' on the executable. This is an important distinction because it means if you set the "Run this program as an administrator" attribute on an executable, it doesn't matter how you run it (from command line, from shortcut, etc.) that program will run as administrator.
Secondly, you do not have to modify every program. A process will automatically be elevated if the parent process is elevated. So if you always launch your processes from one parent, make that parent run 'as an administrator' and you're set.
I can think of three likely UI entry points for launching new processes:
- The Metro screen "search" feature
- The old-school Run box which is still accessible via the [Start]-R key combination
- You might launch processes using a classic start menu such as 'Classic Start Menu'
In all three cases, the parent is c:\windows\explorer.exe.
Unfortunately, you cannot make explorer "run as administrator" because there are no "properties" exposed for explorer.exe in the UI. However, there are ways to run explorer.exe elevated. For example:
1. Launch an elevated command prompt (cmd or powershell)
2. taskkill /im:explorer.exe /f
3. run explorer by typing "start explorer" - or if you're in powershell, you'll type "iex explorer"
This kills the existing explorer process and replaces it with an elevated one.
I found a simple tool called "U Are in Control" which makes this a little easier. It will work in Windows 8 RT or full, as it is just scheduled tasks and CMD scripts. It lets you shift into 'everything is admin' mode when you want to run normally, and switch back into 'everything is normal' mode when you need to launch Metro apps. When in 'normal' mode, only new processes are run with normal privilege. Existing processes would still run as admin.
