Deleted programs from start menu?

Hm,my english is maybe not good enough to explain this but I'll try.
So let's start.
Maybe a week or two ago I was cleaning a junk from a system with revo uninstaller and have checked few more options then they are checked by default,and I erased some of the apps from start menu.That were apps which are in Accessories and System tools folders,and all Administrative tools folder.
After that I tried to approac them through Administrative tols in Control panel,but I was getting a message that a shortcut refers to a location which is unavailable,and that they are maybe moved to some other place on HD.Since I knew what have I done,and it was 3:00 AM,I decided to do a System restore,but some other day when I won't be sleepy.
Tomorrow and day after tomorrow I was kind a busy,and forgot to do a System Restore,but I was downloading some games and I was running out of a place on that partition.I was maybe a few hundreds megabytes short,and decided to delete all system restore points and turn off system protection,so I can get some extra place which was earlier dedicated to System restore.Off course,in that moment I forgot about the programs I deleted few days before but I remembered them in the same moment I turn off System protection and when restore points were gone,but a second or two too late.
So,my question is:
Is there any way so I can get back System tools and Administrative tools back?
Of course there is because I see some of them in System32 folder and in Windows folder(exe files) or maybe they are all there but I can't tell which one was where,and I don't know how I can get them back in Start menu,and reassociate Administrative tools with Control panel shortcut.
And of course,I don't have an image of a system.
I hope that you undersand what I was trying to tell.

I'd agree you may want to simply do a repair installation.

If you really just lost the start menu shortcuts, however, the folders for things like Accessories and Administrative tools are in the folder at:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs

(e.g., C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories)

... and the relevant programs then simply have shortcuts placed in those folders.

The calculator, for example, is a shortcut to:

%windir%\system32\calc.exe

The character map is in:

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\System Tools

and has a shortcut to:

%windir%\system32\charmap.exe

The administrative tools don't look like they'd be quite as easy to reassemble though, especially given their separate menu and presence in the control panel.

If it was me, I'd back up anything critical and try the repair install.

Yes,that is what scares me the most,because when I try to open Administrative tools from Control panel,I'm getting some message like"...shortcut referes to location what is unavailable",so I'm affraid that maybe Administrative tools aren't where they use to be anymore.
I also looked in start menu folder under Program data,and folder is there,but programs aren't.
Funny thing is that I recently tried to find paint through start searc and wasn't able to find it,but when I try to edit some icon or something,it suddenly shows up.Seems that I'll have to reindex C drive again.

If it was me, I'd back up anything critical and try the repair install.

It appears that I will do it that way too,but I will wait another build or official announcement that 7057 is RC1,what I don't believe in.
Thank you guys
